I'm guessing you're somewhere in the 400-420rwhp range. What chamber volume are those 195s?

Compression isn't the issue, it's CYLINDER PRESSURE. You're pushing it with a stock motor on a true 200...

I ran that tune relatively untouched for 25k miles with my old stock shortblock. Got 27.8 mpg with the cruise on at 65mph, idled at 800 rock solid etc. Just make sure your constants are all setup...

I may have a tried and true cc306 and ported head tune for you to try

I've got a nice truck and trailer now, the Camaro has become a race car. No sense in spending more to go slower than with a big bore block... Right now I'm leaning towards a 15° tall deck 441.

Picked up a virgin 327 block with 643 heads last night to built a stock headed budget 355. I suffered some catastrophic bottom end damage on my 389ci motor, so this will keep me occupied while I...

Give the 6a box a try, but I think there's power to be had especially when you spray it.

I'm at 13.25:1 and I run a -8 plug NA. On E85 you DON'T want an extended tip plug, you DON'T want a hotter plug, and you DON'T want a big gap. I run .022" NA. E85 likes to be fat, if you're less than...

Probably 977s, need to put em on a spring tester. I think 977s have been used on the LPE stuff.

I wouldn't even push 12:1 on 91 octane. I speak from personal experience. Every tank of gas is different, if you want to push it with inconsistent fuel then budget for a rebuild.

I'd run a 1/2" supply

SHP blocks can be ordered with a BBC cam tunnel for no extra cost IIRC. Not a huge benefit but definitely one for the high rpm N/A guys wanting an SB2.2 setup. Just wishes and dreams now!

In regards to the different posted specs above, earlier IVC should read earlier ICL... more lift earlier in the intake cycle (before and shortly after TDC)

Still running a hydraulic with shimmed FACTORY lifters with about .017 plunger travel. 215/490 pressures with light valvetrain and stud rockers. I've been 7600 rpm all last season cam is 267/272 and...

Big springs and pushrods:

242/250
.660/.620
105 ICL
108.5 LSA

I think:

245/252 @ .050
165/169 @ .200
.610"/.600"
104.5 ICL
108.25 LSA

7500 is comfortable without needing hollow stem, 5/16 stem, or titanium valves. If we're talking 110 grams or less on the intake side there's alot you can do. Pushrods are as important as the...

Opti is good for 7640 rpm in mine... highest rpm I've seen with it. I don't worry about it one bit at that rpm.

Nothing fancy is needed for 7500 rpm with a SBC. I'm going 7500+ through the traps with a hydraulic roller, heavy cola crank, heavy 4340 H beam rods, and 434 gram pistons.

A valve on a 23° sbc cannot physically drop into the cylinder. What happens is the valve makes contact with the piston and bends, or breaks the head off the stem. An inner dual spring will not...

As if the light second spring would prevent piston/valve contact? Cmon guys...

114lsa is terrible for an LT1. ICL isn't mentioned but you can put it where you want it ;)

I tried looking but don't have the vids on my camera where we tried a higher tire PSI and it just spins at initial hit :( I can feel it in the car, when it hooks and spins, spins period, or really...

I'm 100% stock suspension up front except for the coil overs... seems like a double whammy that I'm so low up front, and the suspension doesn't move freely at all. Your car moves out in 60' dude,...
