chevy 350

my friend has a chevy 350 just rebuilt only 2k on it now. it is pushin 350 hp to the wheels it comes with (trans and drive shaft). for 500 i will be selling the trans and driveshaft. he is selling it to me for 500 dollars. what kind of transmission do i need for it to run and how much and what else will i need. can u give me a estimate and is it worth it. my jeep is a 05 x series/automatic.

See what trans he ran and use the same. . .Also think about an axle.

I'd say if you want a 350 Chevy, it's the more popular swapped motor and has great after market support for the swap.

I'm not too sure about an 05 wrangler, but I did it in my 83 cj. You're gonna need engine mounts, exhaust, adapter bell housing, possibly new radiator for different hose locations (mine were on opposite sides), and all components to make the engine run. Research your tranny, it might be strong enough to handle it. I went through Summit Racing for all my engine needs, and 4 Wheel Hardware for adapter needs. They both have excellent tech departments for any questions.

From all my research and my uncle doing same swap... your going to need a larger after market radiator to keep that beast of an engine cool. Depending on how much off-roading your going to do you might should get dana 60.... a good website for this conversion is

run a 700r4 or allison trans. if you can find the allison....keep it even after the engine dies.

also...if my chevy 7.5" can handle 450hp out of an lt1 383, i'm sure a dana44 will be enough for the 350. i had 450tq and launched at 2800rpm and never had a problem with the rear...and the dana44 is almost an inch bigger ring gear.

also, if you get a 3 core stock replacement you should be fine with some electric fans.
