401 carb choice.

[leanz]

My 401 has estimated 11.5-12:1 compression, .520 lift cam-- I'm wondering what would be your first choice for a carburetor. This is in a Jeep, will be used for offroad, I'm not a big fan of radical inclines, so I dont really care about fuel injection.

I'm looking more for a CFM recommendation, not a carburetor brand because everyone has their opinions on which brand is best, yatta yatta.

Thanks! :wink:

I would use a holley truck avenger 770.

What kind of fuel do you run in that thing with that kind of compression?

[leanz]

well it fired a few times on 93 octane and a really messed up holley 750 , so it only ran for maybe 30 seconds on 40% throttle then would die, but i think for the break-in process wit my new carb, ill run whats left in the tank of 93 octane (maybe 2 gal) and just fill up with 100 octane or higher and see how she does :lo1l:

I'd say 101-103 octane and she'll run, providing it's mechanically sound... 93 octane on 11.5-12:1 cr.... Please let me know how you do it... my 360 is 10.5 maybe a little higher and she doesn't like 93 etc... 100+ and she's sweet!!!

with the right cam (something that doesnt build a lot of cylinder pressure) and conservative timing it should run but definately not to its full potential. :lo1l:
