Holley 650 Ultra double pump to big for a 302?

yep those are nice! you can change the entire fuel curve and even tune the emulsion characteristics to whatever the combo prefers. Have you seen these dirt cheap knockoffs made by procomp, speedmaster, or whatever name the use now?

I would be very afraid of machining and even measure the bleed/jet sizes before bolting those on anything I cared about. Can't believe the price though. I bet some have decent luck with the quality when they choose to draw straws with their credit card.

 

Yeah I still have a few week before winter lets up here in Michigan. The guys that have the dyno are really decent guys. $80 an hour that,s me working with them. They build a lot of the rice rockets and ship them all over the country. I was over there last fall they had a mazda that they where dynoing at 1800hp, huge turbo,s on them. but they also love the american mussel also.

 

That's what we had to put on a friend's 670 Street Avenger just to try and get it to run right. That carb was completely upside down, it idled way too rich and leaned out under power. On another forum I frequent one of the guys said he was talking to a Holley rep that visits his shop. Talking about the Street Avenger the Holley rep said "I wish that carb would just go away".

 

Wow.
