The PO put a new 650 on this 350. I added a 700R4 and still haven't id'd my rear end yet. I am thinking about putting the Edlebrock 500 on my engine. It says it's the gas economical version. What do you estimate it will do to my MPG? Will the power be a great deal less? The engine feels over-carbed with the 650.
