Folks, I need some recomendations on a carb for my 351W. The motor has been bored 30 over, 10 to 1 compression, world product heads, Comp cams solid roller and Torker 2 intake. Cam spec's are Gross lift 586, advertised duration 288 I&E @ .050 244 I & E, lobe lift 366 I & E on 110 deg lobe seperation with 4 deg advance set in cam. I have had a Holley 770 street avenger on the car and it seemed to be a little to much carb. It was very rich even after jetting it down a couple of sizes on the primary and secondarys and would bog when full throttle was applied. I then switched to a 570 street avenger and it runs much better but it has a stumble anytime you increase speed normally or at WOT. I had a 65 mustang with a warmed over 289 and ran a 750 vac secondary with none of the above problems and also ran a 650 double pumper on the same car. I want to get this resolved so I can start putting some miles on the car with out fear of being to rich or to lean and hurt the motor.
Thanks in advance, Ray
