A 750 isn't too big by any means. You might consider upgrading to a DP, but if you're more comfortable tuning Edelbrocks you can stick with one of those.

 

With 210 heads, 750 will be fine. I would personally run a Holley style as well though.

 

im not a carb head but whats the benefits of a holley over a edelbrock? and would my fuel psi change since going bigger carb?

 

Carbs don't care about pressure as long as it's not too high.

 

Aftermarket support. When you want to start tuning or modifying the carb, a Holley style is the way to go. There's lots of carbs out there based on the Holley design. Edlebrock is based off the old Carter AFB and nobody else makes versions like that.

They both have their own advantages and disadvantages but the Holley style is more preferred. Even looking at a basic 750 carb. There's probably at least a dozen different list numbers for a Holley 750. Not all are the same and they all perform differently. At least you didn't suggest the Holley 3310. They need to stop making that old carb.

Not sure if the Barry Grant Demon carbs are still available. They had a lot of good design ideas that Holley should have done decades ago.

 

will the 4160 holley model work for my application, or the 4150 series? i was also looking at the 670 street avenger, will that be better for street/strip? i race maybe 5 times a year and want street performance with help at strip

 

anyone got any advise?
