I just did a heads cam 346 and realized it needed way more. I made a deal on a d1. My current combo is a -2cc diamond piston, prc stg1 ls6 heads in 58cc, and a 228r with a 114 lsa. Ive done several compression calculators and they have all been different, but i think its about 11.5:1. Im guessing ill have to change heads to something more boost friendly. I was thinking about some 317 heads? Can someone help me get a plan together? thanks...

 

317 heads would help. and a more boost friendly cam would help as well. something in the mid 21X to mid 22x with .56-.57 lift on a 114. I have some WCCH 317s for sale if interested send me a PM.

 

The cam will work good with a D1, it'll need a little rpm to make full boost. I would go with a set of ported 317's and let it eat.

 

just got a set of 317's heads from thompson. 71cc should get me right. now on to all the other stuff im going to need. anybody want a kidney?
