TubbyZ28 returns?

[SSlowBoat]

Picked up this 94 vert Sunday, this is the car I should have bought in Feb but couldn't afford it at the time, so instead I got a 98 mustang vert. sold that Friday, worked a deal on this, and brought it home.

bone stock other than 4.10 gears, ebay longtubes, elbow, Cai, and aluminum rad. the previous owner definitely made it look the part. but it has a header leak (he used the gaskets that came with the headers) a slight rocker/lifter tick, and he wired the fan to a switch, with speaker wire, off the power acc fuse no relay smh.

those issues will be resolved in the next few days. even Ltconvert agreed, for what I got this for, even if it needs a bottom end, we have one and it's worth it. this is damn near as clean or a hair cleaner than the firebird. https://uploads.tapatalk-cdn.com/20240827/babd6775c7366d32200cf11ef4962593.jpghttps://uploads.tapatalk-cdn.com/20240827/7ec703798da7b9f78588fce25054835b.jpg

Dats more than just pretty. It's like a real pretty girlfriend that also has big tits.
NICE

[SSlowBoat]

already fixed the hacked fan wiring. he installed an amazon aluminum rad/single fan with nice shroud, but just cut the factory wiring off. i fixed the wiring and fixed the tune. also he had the tcc lockup turned off for whatever reason when he tuned it for the 4.10 gears, i corrected that, and made the shift tables and kickdown percentage less aggressive to drive a little better. took it for a ride last night, and of course the new water pump he installed has a small wheep somewhere, smh.

one other thing that is something i noticed when we looked at it is the oil pressure gauge reads low. he claimed he ran 10w30 mobil one in it, but it seems thinner than that, he also did have the cluster out though when he did led bulbs in it, so not sure if thats why (alt gauge reads high as well, and fuel gauge is a quarter tank higher than reality) but coolant temp and mph/rpm read correct per eehack.

i bought a mechanical gauge that im going to tap into the fitting above the filter after an oil change tomorrow, and also going to double check the pickup didnt fall off.

other than those few small things, it feels good cruises good runs so far good

[JOATMON]

The OEM oil senders are notorious about reading low. But then GM didn't set the oil pumps up for much pressure either. I've always said , if the lifters ain't tapping at hot idle, the gauge is lying. I had a '89 GMC truck I bought new that always read real low oil pressure. At about 100k and something miles the gauge drop to zero one day and the oil warning light came on. I was oh shitting til I realized the engine wasn't knocking and the lifters not tapping. Put a new sending unit on it and was shocked to see I had 40 at idle and 60 cruising.

I've always said , if the lifters ain't tapping at hot idle, the gauge is lying.slight tap at #1 exhaust and #2 exhaust, but it could very well be the header gaskets. changing them to some 1406 and red rtv tomorrow, along with a moroso 22459 oil filter and some 10w40, and a mechanical gauge ill put in the cowl old school

HMMM, Hope its not OP related. The '94 Z28 my wife used to have always read real low. When the warranty expired, I switched over to 20w50 Castrol GTX changed every 3k miles for the 30 years that we owned it. I went with the 20w50 because the factory tune runs the engine so fuckin hot the oil gets thin as water. It was never modified in any way, left it bone stock. Only had 120k miles on it when she let it go.

checked the oil pressure today. 18-21 psi at 650 idle. calling it ok. this is with with 10w30 mobil 1 according to p.o. so switching tomorrow to valvoline high mileage 10w40 synthetic and a moroso race filter.

Car is now also called patches. floors have been patched atleast once. oh well. win some lose some.

my daughter has expressed interest in this being her car, so it will get fixed. it's otherwise a really decent car. Just some bs to fix like wiring/replacing front speakers, redo passenger side plug wires, found 6 cut by the ac delete pulley and 8 arcing on header. atleast he included new plug wires [emoji23]https://uploads.tapatalk-cdn.com/20240831/af0e276c27e78c9dd108d72e53d807aa.jpghttps://uploads.tapatalk-cdn.com/20240831/fb3e291c2217b1e371655c15736ab582.jpg

suspension is stock height front with new stock parts, rear is stock spring with 1 coil cut.

new fleabay valvecovers coming today, I don't like the cheap spectre ones previous owner installed, the oil cap is loose and I do not like the open breathers with a maf.

Oh, Those are Torq Thrust M's. They almost seem to have a satin finish. The ones on my car are the TT2's full polish.
I'm an old school Cragar S/S five spoke guy. The Chrome Cragars have always rusted as you looked at them. They make em in polished aluminum now but the price is stupid.
The American Torq Thrust is a decent substitute at a decent price.

back to the cah. today valve covers swapped, tidy up wires and such, replace the broke #6 wire, install catch can and pcv back to normal instead of the open breather shit. add a few clamps here and there on the rad lines/overflow line. changed oil to 10w40 valvoline high mileage full synthetic and moroso 22459 filter. cold pressure is now 50psi, tapers to 30ish hot. I'll take it. dash gauge is still low, so whenever intake comes off to get resealed the sender will get swapped.

the ticking is definitely the header gaskets. found 3 header bolts loose. I want to drive it today before shit weather so the header gasket swap and copper rtv all the slip fit connections will be another dayhttps://uploads.tapatalk-cdn.com/20240831/82d6f9cffb6f093678c3885f5e8cb5c2.jpghttps://uploads.tapatalk-cdn.com/20240831/c53e7788eecd85fde50a31178d7ece4a.jpg

cruises well just has a slighty poop idle at a light on the brake waiting. gonna order some new tr55's (has tr55ix in it of unknown age) but other than the exhaust rattling on the vert brace and the possibility of the muffler having something loose inside it all is fine. suspension feels tight other than the stock replacement gabriel shocks being soft. it'll eventually get bilsteins or konishttps://uploads.tapatalk-cdn.com/20240901/09ad178d486a4ae74b89bf3ea835d6c7.jpg

slowly working thru this thing. last weekend we took it to island dragway cars and coffee before the rain, then came home and taught my daughter how to replace header gaskets. she wants it as her car, so I told her she has gotta learn how to do stuff, her work and grades will be rewarded.

the cheapo speed engineering gaskets and bolts are garbage. felpro 1406 installed with arp bolts. refit y pipe, but something in this hooker aerochamber rattles when it gets hot, like a baffle is borked. still seems like there may be an exhaust leak ie header Crack between cylinders 3 and 5. oh well, that will get resolved over winter.

I noticed this week when it gets hot it kind of idled funny and a little rough, so decided to swap the ignition coil/icm with one I had laying around. p.o. used Amazon ones, so just figured I'd give it a shot and clean the maf as well. wellllllllll no matter how pretty something is, there is always some bs lurking. found the icm/coil wires as well as the maf wires were "repaired" at some point, ie stripped and twisted together.....wtf

fixed all that stuff and then reset the tb blades as he cranked them open but hot iac was at 0 counts. seemed to help with closing down from .67v to .55v now counts are at 30ish hot.

think next step is some suspension stuff, I want it a little tighter handling and a little less wandery on country roads. going to start putting together the spare motor for it with most likely a summit 8806 cam (summit hot cam) and LE1's just for some sound

today we went to Engines for Emma, a big local car show for childhood cancer. she wiped down the whole car and filled out her placard, proud dad moments.https://uploads.tapatalk-cdn.com/20240914/8c0ae377a3f3613b24c139f995bf71cf.jpghttps://uploads.tapatalk-cdn.com/20240914/22960e2957ab90711a1bbe923db6fbd4.jpghttps://uploads.tapatalk-cdn.com/20240914/6e302078ff732ec28e5392ff0fe93de3.jpg

actually had a post typed out the other day for this but didn't post it, passed out in bed phone hit me in face and closed my apps lol

see below pics for progress:

LE1 heads showed up. Should be more than enough for this combo, as well as a summit 8802 "hotcam" which is basically a gmpp LT4 hotcam with .560/.555 lift as opposed to .525/.525. Isky guide plates, comp .080 wall 5/16 pushrods, elgin 1.6 stainless rockers (think old pro mag knock offs), mahle 0.026 head gaskets, arp head bolts, my old sbe from my 94 T56 LE2 camaro that's freshish.

we started getting moving on it, but 8th grade means alot of school stuff for her, along with band and robotics. plus I had to go buy myself a truck to tow with, which I spent the last 2 weekends going nuts working on.

Hopefully this Friday/Saturday evenings we will finish cleaning the sbe (it was assembled ran for about 1200 miles then taken down to shortblock, then assembled for the cutty, then taken down to shortblock again lol) and start putting parts on it. https://uploads.tapatalk-cdn.com/20241015/105135d568e0b40624bee6753faa0e74.jpghttps://uploads.tapatalk-cdn.com/20241015/f6a1b3b6023e9188005c8ddfc4eaea57.jpg

Well this one decides to piss me off. 2 lifters will NOT pump up or pass oil thru pushrod. #7 intake and #2 intake. all others are fine. I took those 2 out and cleaned them, soaked them overnight, put them back in different holes, and they still did not pump up .

the sucky thing is, there are limited options for new hydraulic roller stock style lifters now. the "drop in" morel 7717 do NOT work. the oil band is too tall and they cut oil flow completely off at partial lift.

ended up gambling and buying BTR Delphi LS7 lifters. allegedly they are the same as the gmpp lifters which cost nearly triple. they will be here tomorrow

had 60psi of oil pressure with 10w30 in it priming.

7.150 pushrods in. maybe a hair long but I like the pattern on them more than a 7.100 or 7.050 with these rockers. https://uploads.tapatalk-cdn.com/20241107/657b7289cae38fb8b789854109df1d01.jpg

That's weird, Black Cloud. (That's a nickname that was given to an electrician I used to work with that always had something go wrong with nearly everything he touched).
It's odd that Catmaigne and now you, have discovered that the lifter oil bands are not always in the correct position to work properly in a conventional SBC even though they physically fit dimensionally. I remembered I have a set of used Comp dogbone style lifters that I would give to you if you need them. But it sounds like your new ones are coming today. It also reminded me that I need to check them in the box and make sure they are not getting rusty.
Good luck with the new ones.

I guess you saw the specs I included. They are indeed +.300 body height so they can be used in original gen 1 sbc or in sbc roller cam blocks including gen 2 LT1.

well it's out. found some not so good shit the previous owner did. the front springs are cut, ok fine no biggie, didn't realize they were cut ON THE CAR AND THE CUT COIL WAS LEFT ON THE STRUT. like wtf. so now gotta order springs smh.

otherwise just a long day, lotta stupid little things that made us keep stopping and starting. I didn't pay attention to the shifter cable bracket and it got bent to shit. Hopefully that isn't an issue later. gonna plug away at it during the week swapping stuff over from the old motor to new.

the old motor, also had white on every plug (i just changed them), 5 had oil on the threads, and the motor with no plugs spins WAYYYY too free in my opinion, so good thing we are taking it out. either the springs are toast or the rings have like no compression. hard to believe it ran as well as it seemed like it did. https://uploads.tapatalk-cdn.com/20241110/73ef16d3188db63f55a2f35680d9f13f.jpghttps://uploads.tapatalk-cdn.com/20241110/993eda31f84ac412ee2e778887a0e4f6.jpghttps://uploads.tapatalk-cdn.com/20241110/d4edd51c9caa32784e8203df86ad101a.jpg

still plugging away. hoping sunday we can stab it back in and make some noise with it. had to donate my og fluidampr that frank cahall gave to me about 13 years ago, right about the same time my daughter was born. the jegs hub has a different od on the locating nub for the balancer, and a new jegs balancer pulley is 213 bux, last i got one a few years back they were like 105 lol.

i have to figure out how to weld up one of the driver side header bolt holes on the header flange then clearance. that was our constant exhaust leak after doing gaskets. since i rtv'd the gasket to the header it came off in one piece, and could see light from the flange side of #5 exhaust runner to the bolt hole in the flange.
