With your setup designed for more rpm, cam wise and converter wise, I'd go with the Air-Gap,,, but its your choice, of course. Take care.

Yes. Alex gets sidetracked sometimes. He meant to describe the Performer as a no-power adder. This I know. I have one in a box around here somewhere. Unless I sold it back to the guy I bought the car from when I sold the motor back to him which he then flipped on Craig's List which is where I got the car to begin with...

Coming soon to a red light near you...

I have ran all 3 and the victor jr intake on my SBF...in your application the air gap is what you need... if it was a stickshift id go with a victor jr

I've run the Victor Jr. on my 302s and 351s but I had a lot more converter. 1500 isn't much on a sbf, maybe more like 2500 - 3000 for a street/strip application with a big cooler. The air gap sounds like a good choice though.

Correction: Stall on the converter is 3000-3200

That sounds better.

Why the solid roller cam? A friend in Albuquerque runs a hydraulic roller in his low 11 sec. 347 Fox body. Much easier to maintain. Sets the valves at the start of the season then leaves it alone. Car is street legal too. I could get you the numbers if you'd like.

A solid roller was recommended by a friend who is a local points leader and Ford technical expert. I was looking for higher revs, too. I've seen too many SBF run down by Cameros in the traps.

Air Gap is more expensive than Stealth, but at this point in the build a hundred bucks is a drop in the bucket.

Can anyone verify that the Holley dash number carb 0-80540-1 (600 cfm) is the legal one in GT. It's specs match the one listed for the 68 Cougar in the blueprint thing. Accepted Products states "All Holley dash numbers are accepted unless otherwise noted"

Thanks for all the input.

I talked with my friend. He didn't give me a part number but said it was a custom grind from Comp Cams. Hydraulic roller with a little over a .600 lift. A lot less up keep than a solid roller and he's the points leader in Pro at Albuquerque Dragway.

600 is max lift for the AFR 1399 heads. I'm at 586 or so and that's close enough for me with dome pistons. I have plenty of time to tweak my car so setting valve lash is no real chore.

A quick question to you; is this your first time racing in Super Stock GT?
Have you talked to any racers that run the class as regards to what is allowed or are you making your own interpretation of the rule book?

If you show up to race in Super Stock GT with the particular Holley carburetor you are referring to, you will be sent home before you even make your first run!

You either run the original OEM carb as shown in the spec sheet or run the approved carb shown in page 126 of the current NHRA accepted products list.

The accepted replacement carbs are shown in the link below:
