L98 heads on LO3 question
 

OK i got another question and im sure everyone can help me out on this....I know if i put the L98 heads from a Z28 i will Compression but they will flow alot better...i have a L98 cam to put in....would i see the best gains with the L98 heads and cam or 305 tpi heads and the L98 cam....My valve's are goin bad on my heads so im goin to get new ones and i figure i should put a new cam in to

My vote is for the 305 heads and the l98 cam, heads should be 58cc, the l98 are 64cc.

Get a set of LB9 heads. Theyll flow well and you wont loose compression.

aluminum L98 heads are 58 cc, if you are only considering the Z28 L98 heads then go with the LB9 heads.

what is the block deck on a 305? Could you make up some compresion by decking the block and/or heads?

The L98 corvette heads and then an LT1 cam....that should bring some flow and more power, right?

thx for the help guys...lol i got tired of messin with my 305 so i went to jegs and orderd a crate motor...i got me the 350 deluex 330hp....i went ahead and got a edelbrock perfromer air gap intake and a 750 double pumper for it...cuz i read in i think hot rod magazine that it bumps it to 377hp...so my lil rs should be a beast after winter

With lots and lots and lots of tuning. I got that setup and its still far from running right. I believe it has something to do with the intake manifold im going to be swapping back to a stock style manifold see if it clears some issues up... But be prepared to tune, or pay some1 for a chip that wont work. ASK ME HOW I KNOW!
