Re: tuned lt4 cammed lt1

Depends full bolt on LT1 on just a cam only car? I read in a camaro mag a few years back with a Hot Cam Kit he hit a little over 300hp. Not sure if that was RWHP or at the crank.

Re: tuned lt4 cammed lt1

hotcam kit will get you up to about 300 maybe 310 at the flywheel.

Re: tuned lt4 cammed lt1

Most dyno numbers over at camaroz28.com seem to put well tuned rebuilt hot cam cars at the 310-350 RWHP range. Just tossing a hot cam in a 100k miles car will be lucky to net you 300 at the crank IMHO.
