I'm pulling together the last few parts needed for my 426 HEMI build. I'm going with a vintage '67 block, 4.15 stroker crank, stage V aluminum heads and rockers, roller cam, headers. All stock accessories. My build is expected to be around 650 hp.

My goal us to keep it stock appearing with the exception of the headers. Car is a 69 GTX, 4 speed.

My question is will a set of original '69 carbs be enough to support this combo, or should I be looking at a set of clone 750 cfm AVS's?

What's your thoughts and experience's?
Thanks

Talk to Scott Smith on here, he can tell you what ever you need to know.

Stock carbs will work awesome on that combo.

I agree, stock carbs will work fine for that combo. So will clones (either the 600's or 750's should work fine, 600's if mostly street driven) I sell both, as well as 800's if desired. The 750's would likely give you more peak HP but you'd be splitting hairs on that one. The nice thing about the clones is that they use all of the Edelbrock jets and rods so tuning is a breeze. Originals have few jet options but can also be converted to the Edelbrock system if requested, no big deal.

Since the clones are built with vintage air horns and reproduction Hemi throttle arms the clones accept ALL of the factory accessory parts so nothing custom is required to run them, stock intake, air cleaners, progressive linkage, return springs, fuel lines, etc. are all 100% factory spec. I can add any choke style desired, electric (shown), manual, or the factory automatic O.E. style.

I highly recommend the stock, progressive linkage with either carbs on a stock intake. I have run both and the progressive is much nicer to drive and I think does way better for fuel mileage. Jetting is harder to hit right on but it's worth it.
