OPINIONS ON BUILD
i posted this another site but no reponse
i have a dart block sbc 383 c1..13.54 cr.......super victor intake ported 4150 intake with a 970 cfm carb, one inch spacer........going to try a 1050 dominator on the dyno...afr cnc 210 heads and ported....roller solid 264-272 at >050 with .634 lift with 1 3/4 ceramic coated headers the motor dyno just under 600 hp anyways i am going to change the pistons and make the motor a 409 c1......4.165 bore x 3.75 stroke has 6 inch rods but the pistons depending on the head gasket thickness will be from 13.0 to 13.1....i am giving up some compression from old build how much will lose by going down half a point 7-10 hp and how much will i gain by going to 409 ci from 383 ci.....i am guessing it will dyno at 637 hp with the 4150 carb and 655 with the dominator.........am i close and what do you think............thanks
