I bought a 454, with stock compression and small oval port truck heads. I suspect the compression to be in the 8.0-1 range. the guy swapped cams, its an RV cam .500 lift, with .238 @ .050. I bought a used weiand stealth intake and 750 vac holley carb. With a set of 1-3/4 tube headers will this motor make 325 HP? i just want a daily driver i can run on pumpgas on the highway?
That is a lot of duration at .050 for an RV type cam.Quote:

If the duration is correct I.M.O. you have to much cam for your compresion.
With that low 8.0 to 1 comp. ratio.I would look at cams that are no more than 210 to 215 at .050. for duration.
how about this cam 500/500 22/234 114 #12031 howards this is close to a mercury marine cam this cam with no cr will make 330 hp in a 454 thats was mercury said they made so you should get that +they had a stock iron intake low rise type . i have us this cam in some builds i think it works very good with low cr
Ok the guy i got the motor from was guessing at the cam specs? I will have to get the grind number and look it up. Thanks for the reply guys, this motor is going in my 69 chevelle, as a daily driver.
