Hey just had a question for you guys... Is a Holley 760 a big enough carb for my pretty much stock 454???
-
Yes
-
If I try wot it starts to die and miss.... Any ideas?
-
there is a ton of things it can be! for starters,
dirt in tank blocking pickup tube.
fuel pump starting to fail
carb needs to be rebuilt
distributor advance curve not right or shorting out
Thats just to start! what else is it doing ???
-
I know your boat ran right..... Now your asking about another carb. I'm assuming this isn't the carb you had on your boat when it ran correct ! If this is the case and your trying to mount a USED carb, not a problem, but ALWAYS spend the 50$ on the rebuild kit.
You'd might be surprised how much a dirty/ needed rebuilt carb could throw things off.
Good luck.

Well It would really run at all with the carb that came on the boat so we put another carb and it ran a 100 times better! It will one run for one pass but once you shut it of it won't fire back up?? And I'm gettin the carb rebuilt this week I'm hoping this is the problem... And it's got a brand new dizzy I just put in it last week and it has nine pounds of fuel pressure so it's gettin fuel.

Wouldnt*** really run

you might be getting to much fuel at 9lbs. You floats can be to high in the carb, your air bleeds on the carb may not be adjusted right, you can have a vacuum leak, the timing is wrong, the list will keep going. With 9lbs of fuel pressure would check the float bowl levels, and make sure the needle and seat are working.

you may need a fuel regulator with 9lbs of fuel pressure....5-7lbs is where you really want to be with fuel pressure on a pretty stock 454.
