Thread: need help with 327

Tweet

thats a 2 bolt main block. Since it is Pre 1968 its small journal (rod and main journal is smaller then blocks manufactured after 68). HP is probly 250-280 i would say. (67 corvette 327's were 300hp), Compression would be 8.5 or 9.

Im not familiar with a 142 blower but a blower is a blower so you would need a 750cfm carb (most ppl run them on 142's and small blocks im told), headers, cam pretty lumpy if u are going supercharger, intake (get one to match cams's rpm range), raised compression (10.3 is nice to run on pump premium but u can run as high as 10.5 on pump premium), consider some heads (dart, vortec, 202 turbos, etc.), i dont know about a small main journal crank if they even make them :S, pushrods, valve springs to go with cam, ignition system maybe, the sky is the limit. but i would do all those before doing a blower.

if i were u i would take out the small journal block and either put a large journal 327 in its place, or a 357 (350 bored .040 over), or a stroker (383 (350 with a 400 crank bored .030 over) )

maybe consider doing a big block.
