ive got a 1976 400 that I raced many moons ago ! It was a build just as yours ! Rings , bearings , oil pump home valve job , cam . Wiend intake 750 4150. 8.2 to 1 comp I think. 3000 stall 56 gear 10.5 slicks . 8.0’s 1/8 in 4000 lbs B body ! I was thinking about doing it again just as you are doing ! That same stock short block and throw a set of 240 trick flows on and trick flow track heat that I just happen have still in their boxes never been installed on anything !! I just wonder what that dude would do?? I know the compression will be higher do to the 78cc chamber ! It’s got 452 on it now !!
