750 Edelbrock issue

harrisonm said

I had an Eddy 750 on my 340 (modified to about 375 HP) and it ran great. It did smell very gassy when I drove it. I downsized the front (primary) jets 2 sizes and that made a big difference. It was still GREAT when I put my foot in it, but driving in town and in traffic was way better. After 10 years with the 750, I switched to the Eddy 650 Thunder. It is a great carb.

I had heard that, that a 650 would work just as well. On a street application.. I mean if I was flooring it for 1/4 mile with more cam then yes definitely 750. i may pick up a 650 just to have one and do some switching around when I get this thing back on the road. I'm not one to do calculations ( well I may do calculations, but i still would wrench on it) I'd rather just take the 30 minutes to swap it out and run it see how I like it. I do have a 600 holley that works well i ran it on my 318.
