Very nice bud. Lemme know if I can help out in any way. At least as much as over the internet as I can.

That's pretty cool. I hope I can afford to do that to my Jeep eventually.

actually..... selling off my old trans and motor has pretty much paid for the big ticket items..... engine mount, fuel cell, exhaust headers and the shifter..... i think i only have $100 out of pocket (trans)
tomb raider..... i got a feeling you're gonna be my best friend thru this!

You going to run carb or injected? Is the donor from an injected vehicle? I just had a block handed to me for free, so with no injection parts I'm thinking propane, pretty cheap to build from scratch.

**jeepin1995** · 02-10-2008, 12:34 AM

it's actually a 350 out of a emergency generator from the local power co..... it got struck by lightning and fried the generator (also free)..... motor runs good, only 500 hours and runs off of propane..... not really my cup of tea, i'm ditching that for a carb for now.....gotta start off easy.....

What headers are you using?

Jeepfreak81 · 02-10-2008, 12:07 PM

Same exact swap I did quite a long time ago, good luck!

Don't skimp on the radiator, I bought a standard conversion radiator instead of going aluminum and have hated myself ever since for it.

I know you mention carb, if your buying a new one you can do a junkyard TBI for about the same price and have fuel injection, also worth it. I have a carb, and I love it most of the time though, but I have tinkered with carbs for a lot of years.

If your planning on buying an adapter to your t-case don't... Buy a 231C for $100 instead. You have to switch to a electric speedo (Autometers anyone) and you still come out ahead of the $500 adapter.

Keep an eye on the oil filter, if you don't have enough lift under full compression the driveshaft can make contact (also depends on your motor mounts), same with the exhaust depending on the headers you use. I kept the manifolds and got around this problem, though I have enough lift now, so if I ever need a new exhaust it will get headers.

I am sure you have already researched all that though. The upgrade is well worth it.

What are the advantages or diadvantages of the AA motor mount cradle set-up over their weld-in motor mounts? I know the cradle set-up is about $80 more but was just wondering if one way is better then the other.

Goo luck with the swap. I hope to start mine this summer.

The bolt in mount forces you to put the motor in a certain spot, the weld in will allow you to place it where ever you want it.

Very cool, I'm in the middle of doing the exact swap, with the same mounts (came with the jeep when i bought it). I'll be watching this thread closely, keep us up to date whats working, and whats not. Keep it up.

OK my experience with the drop-in cradle is that it places the motor very low in the frame. I also had problems melting motor mounts because that cradle put them very close to my blockhugger headers. I eventually wound up going to the weld-on style mounts to aleviate the motor mount issue and also to raise the motor to provide more clearance for my steering ram.

If you are using rear dump shorty headers/manifolds or you have long tube headers, and also have the clearance below the motor, the drop-in style mount will work fine. Personally, I prefer the weld-in style because it gives you more options in final position of the motor.
