750 Holley Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

LT-102 · 11-10-2002, 12:52 PM

I have a 350 in my 71' C20, it's built up enough that the 600 cfm Holley is not big enough for it's performance capability. I prefer 4150/4160 series but, the Avenger 670 cfm is out of reach of my wallet. Have not found a good 650, with vacum secondaries, that will work.

My question is, can the Holley 750 (3310) be jetted back enough to work on my 350? I'm planing on building the engine up even more when extra money somehow arrrives and the 750 will be just the right size, but for now can I make it work as a "happy medium".

Thanks in advance for your help.
