<< < (2/3) > >>

Mr.Pontiac:
Cliff, sorry , yes 110gpm behind the tank. I also have a return back to tank with a no. 10 hose. alot of cam, just trying to figure out why i lost the 3 mph. You stated you run 7.5 psi i am at 6.5 maybe a need for more fuel??? reason i asked

Sonny:
A decrease in pressure should increase volume.

Cliff Ruggles:
The later carburetors will easily handle high fuel pressure so don't be afraid to crank up the pressure some and see if MPH improves.

You'd think a bigger cam would make more top end power and MPH would go up some, especially if ET improved......Cliff

77cruiser:
Did the 1/8 mph drop off too?

Mr.Pontiac:
I believe  i found the issue, no.1 and 7 plug completely fouled. Hay i ran these plugs for just about a yr. guess i should not complain
