Necessities for converting 4cylinder to V8

I have a 2.5L TJ with a 4inch lift and 31inch tires. This summer I want to put a hockey puck body lift in, some larger tires maybe 33?, and a V8. The V8 will come from an old truck my dad bought to replace body parts on his after deer damage. The truck is a 93 Chevy I haven’t checked but I assume the 5.0L. I was wondering if it was possible to use these - For the front axle - For the rear axle
instead of getting totally new axles. Would they be strong enough? Also the truck’s trans. Is an automatic (as well as my jeep) and I was wondering how hard, how much, and where to find a manual trans. For the V8. Since we have the whole truck minus some body is there any other things I would need to buy? I have a lathe and vertical mill for machining parts so I will be able to make things like motor mounts. How about engine cooling?

All you ever wanted to know about Chevvy compatibility.

I mean, how good a site is this!!!?

The dude needs to do some Google optimisation though. For the time takes on that site it does not search well

I think I'll do this once I fix my brake...oh and paint the logos on my tires white

Why not? A damn sight more chunky on other cars with more hp/torque than the TJ. He seems to know his stuff, thats for sure.

I really like the thought of a 'Vette engine in a Wrangler!!!

You might want to think about a suspension change in the front at least. That V8 will weigh alot more than your little 4 banger. Once you put that engine in your jeep might have the stance of a funny car with the hood angled down. I know you said you have a 4 inch lift you might want to see if that kit offers a heavy duty spring, alot of kits do.
