93 z28 Cam question

[IronOutlaw]

I warped the heads on my old car when my radiator was stopped up. It was barely even using coolant but it wasnt getting into the oil.
That motor was toasted a few times, and after machining the heads ran like a champ. These Lt1 motors are tough.
Id try to get him down to around 800 if you could. Even if the motor is bad you can find another one for really cheap these days.
What kind of shape is the car in? If the car needs paint or the interior is shot I wouldnt buy it.

So what type cam do yall recommend? I have CAI, catback, chip, and 6-speed. What all would I need with the cam without getting heads. What kind of prices am I looking at for Cam, springs, PR's, RR's, etc. A guy said a Comp XE 224 could get about a sec faster in the 1/4. What kind of performance can I get out of what cams? Thanks for your help, just lookin for personal experiences with diff set ups.

It's up to you what you want to replace, but I'd recommend at least doing Valve Springs, Retainers, Locks, Rockers, Cam, Oil Change, Timing Chain, Mail Order Tune. If your just looking for a little more power throughout the powerband I'd recommend a hotcam just because it's cheap and comes in a kit. It's proven to be pretty good, extremely drivable, and any mail order tuner can provide you with a pretty good tune for it. A hotcam'd full bolt-on (headers, throttle body, etc.) car should be good for 330 rwhp and run mid to high 12's at the track with decent traction.

I'd offer the guy $800 and tell him your mechanic quoted you pretty high for a head gasket swap and see if he takes it. Worst case scenario you could buy a used LT1 for $400-600 and throw it in the car. Personally I'd pull the heads, have them ported/shaved and spend a little money checking everything out and building it up so you can beat your brother.

A solid rolling body with a good title is worth $800 so even if the motor is completely trashed, you still got a decent deal.


Hope this helps, sorry if I wrote a book.

I have heard the hot cam is very mild and almost not worth it? What do you think?

You said you weren't looking for anything too extreme. It's a comparable cam to the cc503, cc305, etc. Is your brother looking to do anything more in the future? I was going to put a hotcam in my car and drive it until I got out of college (at which time, I'd be building my motor and changing the cam out assuming I keep the car) but decided against it. I thought it was perfect for what I wanted at the time. I simply wanted a bit more power throughout the powerband and a bit nastier sounding idle, while retaining great driveability. You may make a couple more horsepower with a cc503, but it's not worth the extra $$$ IMO.

How much difference in performance do you think there is between the CC305 and the CC503

[93z]

The 305 would be more of a nastier cam and the 503 more street am i right?

hotcam 218/228 112lsa .525/.525 (w/1.6rr)
cc305 220/230 114lsa .544/.544 (w/ 1.6rr)
cc503 224/230 112lsa .535/.544 (w/ 1.6rr)

IMO, cc503 is the best choice if your purely looking for the best power output. But if price comes into play, I'd buy the hotcam just because I'd personally spend an extra $200 in parts with the cc503 (lt4 valve springs are good for a max lift of .550, some people don't like running them on the hotcam w/ 1.6rr) and $200 isn't worth an extra 8-10rwhp IMO.
