461s on a 283 would be fine.make sure the chambers are 64cc. A little porting would not hurt.(little) nothing to not much on the intake side,leaning towards nothing.
What type of camshaft do you like using? what type of drive are you,generally speaking.
Quick recipe with out YET matching the parts,just a general recipe to start talking about,,,,
I would recommend or use,,, a 650 holley double pumper,or something similar size that you prefer(IE 650 edelbrock), performer intake, camshaft would be something like
110991-08 CL110991-08 275 275 221 221 .470 .470 108 104 Hyd. Hyd. 1
1700-5700 Good low & mid-range horsepower. Needs 4 barrel & headers.
this cam would let a 283 rev to 6400
9.2 ish:1 compression ratio,1 5/8 headers,roller rockers,1 5/8 long tube headers.
I would really like to see some improvements in rear gear ratio maybe 3.90 and a posi. a 4 speed with the lower 2.54 first gear.
lets start talking from here
