Needing intake manifold advice

Post  Brandon D on February 9th 2015, 10:02 pm

Background:
1979 f150
460, 770 Holley vacuum secondaries, performer 460 intake
Stock C6
3.50 gears
38.5 tires

I'll be picking up a recurved distributor, straight up timing chain and headers in a couple days.

My question is will I benefit from a Weiand Stealth 8012 Intake Manifold?

Thanks, Brandon

I would look at the gear tire combination before the intake

ONLY at Wide Open Throttle and lose everywhere else.

5.13's and a full spool for the rear are on the list.

That's what I figured.

Would I benefit from any other manifold? Say, a Performer RPM?

Intake gasket is leaking so I figured I'd swap it while I had it off if I would see any gains.

The rpm would work fine IMO

Is it a stock low compression 460?

Yes, except for intake and carb, stock motor with D3 heads.

If you have no intention of raising the compression ratio from the factory 7.9/1 ... keep the regular Performer and just put a 2", 4hole spacer under the carb.
