600 CFM, all I need. Check my math!

I ran a 750 Edelbrock on mild 340 with a dual plane intake in a '66 Valiant. I had problems with it being EXTREMELY rich and decided to try new jets/rods for it...that's when I discovered the factory had put the wrong jets/rods in it to begin with (HUGE...bigger than what they even list "factory" in the 800)! Ordered the set that should have been it in...plus a few above and below. What a difference...even got 18-19mpg at 80mph...with 2.94 gears of course. The guy I sold it too didn't believe me until he drove it from CO to NC. He called me and said 18+ every tank except one when he played with it....better than his 318 Duster!

Bought another new Edelbrock a few years later for another project and checked the jets/rods BEFORE I used it...wrong again! My advice...open it up, check what's in it, and play with the jetting. It should work just fine with a little tuning.
