Ok heres my current set up.

L98 350 switched over from TPI to carb

Edelbrock RPM performer intake manifold

Quadrajet 650

Everything else is bone stock other then a set of longtube headers. i would like to run deep into the 12's with this car so i'm looking for some pretty aggressive heads and cam. what do i get that will work with my intake manifold and block?

 

AFR 195 heads.

Comp XR288 cam.

750 Holley or Demon DP carb.

3500 stall converter.

3.73-4.10 gears.

Drag race tires.

Suspension/chassis upgrades to handle it all.

Or something like that...

 

The infamous Vortec heads and XE274 combo will get ya there but you'll have to buy a new intake.

 

what kind of intake would be the best with that cam and heads?

 

Performer RPM is what I have... I've seen good results with Super Victors too. You need a vortec-head specific intake manifold... they're a bit more pricy than standard intakes.

 

oh so i can get a rpm performer just specific to the vortec heads?

 

Yes, but the RPM style only comes in square-bore carb mount configuration. Edelbrock 7516 for RPM Air Gap, 7116 for regular RPM.

Of course, that's not a problem with my recommended carb.

 

i was looking into the air gap before is it really that much better then the normal rpm?

Obviously, not everybody is convinced. And, I don't know of anyone who has switched between them without changing something else.

You know how it goes: You pick something, and then defend to the death why it's better than what you didn't pick.

 

i could be wrong but i thought q-jet's smallest carb was a 700,
i have a comp 268/280 extreme energy cam with 2500 stall and a set of worked double hump heads, 2.02 1.60 valves, i plan on hiting the 12 with this setup

 

The iron lightening heads from RHS will get you there too.
Choose either the 180 or 200cc ports for a 350.
