Has anyone run a Holley 4150 style proform chokeless double pumper on a 5.3/5.7? Stock jets are primary 72/ secondary 80...just figured I'd ask since I just picked up this carb for free since I was running a vacuum 4160 750 Holley on my 10:1 L33 5.3 with performer intake and stock ls1 corvette cam..

Should run fantastic. If you have a wide band you can dial it in.

Forgot to ask zone, but I meant to ask what you thought about the mechanical secondary carb on a ~3100 lb camaro, with 4 speed manual, and open 2.73 rear? I've always thought that your car had to be light/manual trans/steep rear gear(3.42-up numerically) to run a mech secondary carb, and basically I only have 1 of the 3 lol..I'm goin to try it either way, but what's your experience been like with the mech secondaries?

Would be ok driving normal, being smaller than a 750 it may work better than you expect. But the gearing is the real issue. Would be a great idea to upgrade for many reasons.

Yea that's my first upgrade, but since I blew up the spider gears, c clips, and ring/pinion 10 bolt on my 98 z28 last Friday at the strip I gotta buy that rearend first because its on jack stands...them Mickey Thompson et streets aren't no joke lol

I have a 750 DP on my 3400 pound TA with a 5.3. The converter only foot brakes 2000 and it has 4.30s, but it does great at the weight it has.

That's encouraging, I'm gonna throw that baby on tommorrow and see what she got...I spent the night swapping in an eaton posi equipped rear in my 98
