It will be a street and track car,right now i have a 9/11 3500 lock up on the 200r4 trans,3200#,i maybe looking to go to a 76 turbo later and a 400 trans and up the converter to 3800-4000 range. i ve been leaning towards a 224/224 cam but wanted some opions on exact grind i should use-maybe custom? also i may use the S2 aluminum heads i have later with a sheet metal intake.just want to get the basic lower end done and maybe next season go with some upgrades.
