Installed on a 1965 mustang With a 289 engine. Took off a edelbrock 1406 600 CFM which was a little to much for a small 289. Cruises so much better

Excellent choice for lower rpm engine speeds

I've been a fan of the edlbrock carburetor for years. I replaced a 600hp fitek power adder on a virtually stock vortec 350 Chevy in a 83 square body that I restored. I realized the fitek was too big for my application, surging while idling, poor fuel mileage etc. the truck runs 1700 rpm at 60 mph, the 500 cfm carb is perfect for that. It will rarely see over 3500 rpm. Excellent choice for an application like that.

Would Recommend

Yes I should have got this first.
