Another newb question. I've got another one for ya'll that's probably a simple answer but I'm an idiot. If I were to get an OBD II engine out of a '96 model year B-body, is there any reason it would not work with the redesigned year 4l60e? I mean the year they did away with the one piece design and had seperate bell housings and tail cones as well as the 5 bolt tail. I think they did this in late 96. I was going to get said 4l60e from a '97 Tahoe.
Thanks!
Thanks!

im not sure on tahoes, but from what i understood, 96 and 97 year 4l60e were the same (at least on f-bodies). The earlier ones had a different shift solenoid.
I saw something similar in the impala forums, and they had a tutorial step by step instructions and a lot more details. They got it to work, there were just a couple things that they had to switch

Ok.. so I've been looking more into it, and it seems the '97 L31 Vortec engine is more based off of the Gen I SBC. Anyone have any experience with the L31? I may go that route instead... I imagine headers, CAI, and all the other bolt ons could bring the L31 up from 255 hp to near 300.

Appariently the valve cover setup makes for a much more difficult process of installing RR's
The intake has it's issues. Appariently with the wild *** fuel setup blocking air flow, or the 'spider' as it's called. 19 lb injectors? And appariently the poppet style injectors are bad about gumming up.
With those in mind, IIRC RR's and injectors are basic bolt ons. Plus, I am still not sure if height will be an issue. Is the L31 intake as tall/taller than the LM7 setup?

im not so sure about the l31, but dont believe everything you hear about the opti on the lt1. Yes it can be a pain in the ***, and its pretty expensive to replace, but the 96+ had a vented opti wich really helped out its design. My original opti lasted 197k miles and it wouldve been well over 200k if i hadnt sprayed it with water.
Id probly check on the aftermarket for both engines. As i said, i dont know much on the l31, but the lt1 still has a pretty big variety of performance parts, and can make plenty power for pretty cheap.

Oh, make no doubt I would still LOVE to use a good LT1 engine. No 4x4 can argue with peak torque in the mid 2k rpm. My main concern with the LT1 is whether or not it will bolt to the '97 Tahoe 4l60e. If I can find out that it will bolt up and to and work with that transmission, then I will jump on the first '96 B-body LT1 I can find.
The only reason I considered the Vortec was for three reasons really:
It's a truck motor
It may be the only engine to work with it's 4x4 mated 4l60e
The cooling system would more easily work with my XJ, since I wouldnt have to reverse the outlets/inlets/filler neck, etc for the reverse cooling of the LT1.
