Is any body here running a caddy motor with a automatic tranny in there truck? Is a chevy tranny the same bolt patturn as a pontiac / olds / buick? If not does any body make an adapter to bolt up a chevy tranny to a caddy motor?
Any info would be great, I have a line on a free 472 caddy motor.
Thanks for the help!

I believe the Caddy motor will bolt to a chevy bellhousing. Although if the 472 came out of a front wheel drive toronado, I am not sure. If it does, I would jump on it since those motors are torque monsters at low rpms.

The caddy will bolt to a BOP Bellhousing. It wont bolt to a chevy tranny unless it is one with dual bolt patterns. MTS has adapters, but I wouldnt do it. :barf: The BOP is not that hard to find. Talk to your local race shops/clubs. Check out http://www.alaskaoffroad.com/newhybrid.htm for some pics of a caddy in my 76 Chevy.

I bought all my parts for my first engine from Cad500parts, but I will probably get the nex ones from MTS.

What tranny are you runniny behind yours?
:usa:

I am running a TH-350

http://www.alaskaoffroad.com/tech_2.htm talks a little about the tranny, but mostly about the transfercases. Might not help much.

I put in a Cad 472 into my Blazer. Love it. Went with a BOP (actually the original Caddy) TH400 that received a 4wd output shaft during the rebuild.

ryeguy,
How hard was it to swap the output shafts, did you have a second tranny or did you buy the parts some where?

Thats how mine got there! :smokin: next time I think I will do it my self

I thought that tranny cases were different between 2wd and 4wd, I did not think that you could swap the output. How hard is that to do?

I picked up a core Chevy 4wd TH400. The guts were fresh in it (cracked case) and were in good shape. So were the guts in the Caddy TH400. My mechanic mixed and matched between the two transmissions to assemble my TH400. So lots of parts were indeed interchangable. The housing flange (after removing the Caddy tailhousing) is exactly the same between the Caddy and Chev versions, so it "looked" exactly the same as a Chevy Th400 as far as the T-case was concerned. It meant full disassembly of the transmission to change the shaft, but that was going to happen anyway...

Marvel at the Unimog axles and reversed NP203 coupled to the NP205.
He's too modest to admit it but he's entrant #7 in the Fourwheeler TTC event. I think his Blazer has a very good chance of winning. It's fully street legal, has 19 inches of ground clearance under his lowest point, runs 44" tires, and will run at any angle. Oh yeah, it's frickin' tall, too. But thanks to the 'Mog axles, it's also flexible enough to crawl on the rocks. Best of all, it's a fullsize that's built for offroading, no street/show, which many of the past fullsize trucks seem to have been. This is one fullsize that has a very, very good chance of taking the trophy.

everyone here knows that a fullsize will kill jeeps
so the 'this is one' comment is misplaced.
