My latest swap, 92 Cadillac STS!
I finished this project last week and it took about two weeks worth of time to do. The car is a 1992 Cadillac Seville STS that originally had a tired 190K mile 4.9 slug, it kept overheating and didnt run the best so the owner asked if I could put an L67 in it. I thought about it for a week or two and said OK lets do this. The engine/ trans are from a 00 Bonni, Thanks Ed! It shocked me that really nothing from a bonneville would work in this car and I ended up using W-body stuff such as axles, one dog bone bracket, side trans mount, and a few misc other things. I had to make my own front lower mount bracket and a shorter dogbone for the top. The engine mods are 3.4 pulley, 2.5" downpipe, and fenderwell intake. For the size of the car it really runs well and pulls up top a lot better than I would expect. There was a lot of custom wiring involved in this swap also and I had to retain the stock pcm to keep the HVAC system functional as it relays data over the data stream. The dash also has a digital info center built in and uses pcm data for that also. All in all the swap went pretty well, most of my time was spent driving around finding things that fit! Radiator hoses were a real chore, after my third trip to Napa I just went in the back and started looking at hundreds of hoses and came up with a few that worked, W-body and H-body werent even close to working which suprised me. Here are some pics of the swap.
