i would say to much lift and dur for stock heads intake, and exhaust manifolds..

best cam ive ran in something like that is comp cams 260 extreme enrgy cam..

speedway has some tough cams were you can get lifters plus cam for under 90.00


i had a stock 305 with i think it was a blue racer or wolverine cam i bought from advance auto parts for 79.00 for the kit and ran side by side with 413' 406's, and a 388 all night.. it is a copy of the 375 horse lt1 cam..most people always go way to far on cams. without compression, porting and polishing anything over 480 lift is a waste of money time, and fuel..

I agree with you sc1, I had a big 'ol cam in a pretty much stock motor and it was a dog, I took it out, and put a comp. 268 duel energy cam in,It made tons of more power,I could pull'em 3 car lenghts on restarts!

don't mean to but in on someone's post, but I have a cam question also! a 377 motor with bowtie ported heads, bowtie high rise cast intake, stock cast exhaust. the cam I had in it earlier this year was a 550 lift thats all I know (don't have cam card) it pulled very hard but was miserable to tune, can I go smaller without sacrificing performance too bad. Engine builder said he chose that cam because it was the most efficient cam for my motor. if so any ideas,by the way we do have a 14 lb a 1000 rpm vac rule but i have never been in a position to get tested lol thanks in advance

17j.....I like the last cam you listed way better than the others for your application, it is not too big.....I'm not sure about retarding it though, I would install it to the cam card specs.....i think the little extra $$$ will pay for itself in a few races... good luck

17j dont woryy about adv. duration. just look at dur at .050. that is what counts
with the set up you have, i would not go bigger than 234 dur at .050. something around 228/234 at .050 with no more than .480 lift should do fine. thats my input

personally i like your second cam. what did youe ex manifolds come off of. 88-95 chevy truck manifolds are supposed to be one of the best flowing sets out there

Check out the BlueRacer .488-.510,I think the duration is 234-244,it's cut on 107 and 117 centerline.This stick is awsome in low budget motors.
