Having had to fix quite a few of these gems I would highly reccomend continuing your search and finding something better. An ls engine comes to mind first especially if you want fuel injection.

They are NOT problematic engines. The 4.1's and 4.5's were. "Caddy electronics"? You do know it's just a GM built engine with 4T60e trans, right? 20k with reliability issues? I'm not worried. LS1 engine? Not quite original enough for me. Thanks for the advice, though.

Im completely aware of what this engine is. Aside from not being able to physically bolt the the engine to the trans. The stock computer cant control a 4l80e.The mounts are going to turn into a fabrication nightmare. The point is its a lot of hassle for little payoff in name of being different. Theres a reason certain things become popular and others dont. Its not because people dont want to be different its because some things work well and some dont. Its your time and money have at it. Good luck.

I can't wait to see pics of this. Sure it might be a pain and in others opinions not worth it, but if you already have the motor it will be interesting and different. So go for it!
The trans, a 4L60e will easily handle your power and torque. A 80e will just take more power to turn, doesn't have quite as low of a OD gear and it weighs more so it will hurt your economy and performance. Good luck and remember we love pics!

Good point. I actually have a 4L60e with extremely low miles on a rebuild. It's the 97-up style with 65 upgrades. I also have the ECM from it, and I believe I can piggyback the trans ECM to the Caddy ECM as I have done in the past. I don't think this one will be a "pain" so much as more thinking than most people want to spend their time doing. I have worked out the bellhousing issue. Okay, so I got some confimation and exact milling specifications from a guy in England where they actually use these motors for rear wheel drive English built cars with a 700R, tomato, temato. So, I guess it's not that this isn't a popular swap. It's just not a popular swap in America, and not on pickup trucks. This is not a pickup truck. It is a two door Cadillac in disguise, right down to the suspension. Or it will be, at least. I have black leather, 8 way bucket seats with center console, black leather tilt steering, CD with piggybacked cassette deck, all from 1999 Chevy's. Thank you for your encouragement, and an actual fact-based suggestion. That's what I was looking for, suggestions and advice about the build, not suggestions and advice about not doing it. LOL. I live in NC, where the weather looks pretty awful until Saturday. As soon as it clears up, I will start taking pictures.

I think I have the trans controller and bellhousing sorted. I pray that you're wrong about the difficulty of the motor mount issues, but I fear that you're right. Wish they had the same mount locations as the older engines with the same displacement. But, hell no, they're not even close. Very front-wheel-drivey. I also wish myself good luck. LOL. Thanks everybody. Keep it coming.
