[What'saCobra?]

Use a NEW 850 Holley HP series, single 4 bbl with mechanical secondaries and double pumper. Use Holley recommended jetting. Call them, talk and listen.

I cannot stress enough the improvements in the new HP series. Don't even think about rebuilding a 3310 or regular 4500 series from the past, no matter how nostalgic you are about old is best. They were only so so at the bottom, at best, but very good on the top in those days.

That's why guys are comparing old Holley rebuilds to new expensive Barry Grants and Demons and saying how much better they are. Sure, than the old Holley, you bet. But the new Holley is just superb.

This will provide everything on the top and bottom, because the new HP series are excellent metering at low air flows, which allows mechanical secondaries on the street.

Dominator doesn't meter correctly at low velocity on the street, particularly when cold. Might be fixable, but not by me. Pops, leans out and then floods when warm at low rpm and WOT.

Install a choke if you live in the cold weather. Costs hp remember. Interfers with airflow around the horn. Florida doesn't need one. Learn to start hot and cold w/o choke. If it floods keep throttle on floor until it leans out and starts. Let it warm up a little before you nail it.

If you owned a ferrari in the 50's or 60's you would know to let it get warm first even before shifting and you would learn to live with popping and spitting Webers until they got a little warm and it took a while.
