just bought this carb today for $100 HOLLEY 750CFM Dominator Carb. list #80186-2565 will this work on a 454 bbc bored .060 over with 12 to 1 compression and a .629 lift cam

 

750 is kinda on the small side, i'd be looking to resell it and get something bigger, or research if you can make it larger by swapping parts.

 

does anyone on here know if u can make the cfm bigger with a dominator i was looking the throttle blades look the some size as a 1050 cfm on is it just jetting

 

You can't increase the CFM of a carb without fairly significant modification.

 

so i should just sell it and get a bigger carb

 

I think so. You're going to need a lot of air to feed that thing. I'm assuming you're going to be racing this engine?

 

yes it is going to be raced what cfm carb do u think i will need

 

Here is a carb sizing tool that may help. http://www.4secondsflat.com/Carb_CFM_Calculator.html

IMO, you should call or email BG, Holley, or a carb professional to get your sizing right.

 

If you only have $100 tied up in it then put it on and go for it it's better to be a lil small than too big. I've seen too many cars slow down by stepping up to what they were told is "proper size". As long as you already have a dominator flange intake, what do ya have to lose? It'll either run or it won't.

 

ok this might sound like a dumb question but i put my dominator carb up to a 1050 cfm dominator and it looks exactly the same as mine how do i find what cfm I actually have

 

Check the list number on the carb and look it up. The 750 should have smaller throttle bores than the 1050.

 

ok so yesterday i traded the carb for a proform 850 cfm carb brand new i hope this carb works out good for my engine

 

Maybe a little too late since you've traded, but the flow rating on the
Holley is a wet flow test. It would probably outflow and outperform the
850 Proform carb.

 

is a 1050 cfm car to big for this my set up can get a good deal on it

 

Bolt the 850 on if you already have it.
When you get to the strip, make a few passes to get a baseline, then borrow a 1050 and watch your MPH difference. I'll bet it wants the 1050 all day!
