okay lets say 88 roller with 351W heads, edelbrock preformer intake, holley 600, bbk shorty heaads, edelbrock preformer plus cam with a c4.. will this be noticable at all? estamated hp? whats a good set up for the money do u think? i plan on having atleast a 125 shot nos

 

well I'd up the cam and intake combo, but to give you an idea...my 66 has a 74 302 non roller block with flat top light weight forged pistons, .500/.500 lift cam rpm air gap intake and C9OE heads with 1.94/1.50 valves,lightly ported heads, roller rockers and full length headers and on street tires it ran 13.30's @ 104........my guess is rwhp is 260-270 ish??

 

If i did the complete same without the light weight pistons and just kept stock ones what are we talkin? and those are impressive times for what little seems done to it.. what tranny?

 

and what ratio roller rockers? if i used an 88 block stud mount right?

 

the D70EDA heads are no better than the e7's on the roller block probably flow the same or a little less as they are a 302 head d7= 77 302 head with a 69 cc chambber size so it would make the compression ratio dramatically less than a stock roller setup

they have a 1.78 intake valve
1.45 exhaust valve
