What about a bigger carb
 

620" BBC all motor on gas,14.8 compression-355 cnc dart heads,super victor intake.I have a stock 1050 HP dominator on and was wondering how much power you think it would gain if i went with a bigger carb or maybe a Custom built carb.Thanks

We had a 1150 out of box holley on a 565 sent it to apd had them redo it, bolted it on and gained .15 with no other changes. I think you need a 1150-1250 anyways.

I have a 1250 on my 447 SB2. I would go bigger if it didn't escalate in price, requires a custom carb. I may have to try two carbs on the 460 SB2 we are building... :shock: On a 620 I would get a 1250 at least.

I ordered a carb from Pro-Systems and now see that everyone says talk to Patrick.Well the guy i ordered from wasn't Patrick it was another guy.I hope that doesn't matter does it!!!!

Re: carb
 

shouldnt matter all built sameway pretty much. I doubt Patrick does all the carbs anyways.
