Im runnin dual Holleys(with glass float bowls) on my 54 pickup. With Fenton dual exhaust.
Its a SWEET setup,,no probs. here.
On my 52 suburban, i have dual carters,,its working just as well also. running Fenton dual exhaust on that also.

On my 54 panel i have a Clifford intake w/Holley 4bbl. And early(53+54) corvette dual exhaust manifold. The holley 4bbl is just a bit too much for my 6cyl. I suppose i could jet it down and it'd prolly be o.k.
...........just my dollars worth.........

P.S. Have another corvette dual exhaust manifold....FOR $ALE......
