Thanks f bird.
im going to lay down the total set up.
lets start on top
14" k&n air-cleaner 4" thick, holley 750 double pumper, edelbrock performer rpm air gap intake, world cyl.heads 200cc int.runners, 2,02 and 1.60 valves, 64cc chamber, comp magnum 280 cam,230degr.@050, 480 lift and 110 lobe seperation, installed using degree wheel "to be accurate" 1,5 ratio roller rocker arms, Je srp flat top pistons, 6"eagle i beam rods, eagle 5140 crank with 3,75 stroke, and this hei ignition, maybe i should switch to msd ? or get me this curve kit you mentioned, and should i connect the vacuum advance again ? it felt like she ran smoother with out it ?!
This engine is just recently assembled so there is allot of tuning and testing left, i jetted the carb with #73 front and 75 rear and used 6,5 hg power valve. You did mention earlier i should use 4.5hg valve ? ok
Then comes a th 400 trans with 3000rpm stall converter, 3;73 gear ratio and 26" tires, all this is now sitting in my 72 ss nova.
Thanks for your time and effort. Kristofer.
