340 Build Spec's

That was kind of where I was going. 1 5/8 keeps the 340s "limited" torque down where a street geared car likes it. Not max hp, but usable power low down. You can do the bowl blend, it will only help, but you dont have to..Mine was doen before I did any port work, so they were a 3 angle stone valve job, and no special anything. I would bump static up to 9.5-9.8:1, again, to keep the torque peak lower. I dont think this would be any problem with a properly curved distributor. I would avoid the Holley carbs all together, because i like Carters or Edelbrocks for idles quality and throttle response on stock or almost stock builds. (back to that emmissions testing..lol..Holleys are rough to get through..) Just different tastes for different guys.
