Wait for it......another "what will it make?"
G'day Ash..thanks for the interest.
My head builder doesn't seem think the bore will need notching - although he's going to give it a look.
Comp will be around 10.2:1. Open chamber heads and pump gas will limit what I can get away with.
Re size of the cam - My 3650 lb car was MPH -ing at 111 with a smaller cam and worse flowing heads.....and I'm only looking for 450/460 HP.
DD2003 says 469HP..with the roller.....but I think that may be "optimistic" with my crappy headers.
