Re: Help Needed What Cab Is Good For My Motor
Do you know the 50thou duration figures,,from what you have said i,d probly go a 650cfm dp carb,,on my 351C in a zd i ran a 12.9 1/4 mile with a (std minus choke flap) 650dp holley and performer manifold 3.7 diff 3000 converter changing gear at 6000 into 2nd and 6000 into third plus it had plenty of down low seemed to be just right for this combo,,dyno tests on 347s have shown this size carb to have no problems supporting 400 to 500hp.
The 625 cfm carb you have shouldnt be to bad either but i dont think you need to go to a 750.
Feed my will to feel this moment urging me to cross the line..
We'll ride the spiral to the end and may just go where no one's been...
