What's wrong with the GTO motor? Why not just have GTO trans fixed. There are a few differences between Pontiac and Chevrolet motors.

The motor needs rebuilt and the transmission slips and needs rebuilt and I have never done either of those and don't really know how I am decent with body work but that about all

Sounds like you are doing this for all the wrong reasons. I say don't do it.

You'll need to swap out frame mounts and all the wiring is different because starter is on opposite side of engine as is alternator. Sell the Elco or it's drivetrain and put that towards rebuilding the GTO trans. Just my 2 cents, it's your car.

It is possible to do that swap, however, Pontiac and Chevy motors are different animals, meaning divisions. they purposely were built different from each other. Some others on here have gone this route. I doubt any of them would say its simple, though I could be wrong. But it can be done.

I only would plan to do this if it was easy but knowing that I won't and I'm fixing a n accord then selling that for parts for the gto but I'm going to do some reading on rebuilding the tranny and either rebuildit all or buy a new to me engine that is closer to the correct year instead of what is in it (was told it was a 76 or so Pontiac 400)

In the long run I think the car will be worth more even with an incorrect Pontiac motor than with a garden variety SBC.

I'm not real worried on price plan on keeping it and making it how i like it but one thing i would love is to convert this into a 4 speed but that looks to be expensive

Swapping to a small block isnt hard. But it does take the right means of doing it. Need frame/motor mounts and either re-route the wiring to the stock battery location or fab up a place for the battery on the pass side.

Looking back, I wish I'd spent my money on a pontiac. Seems theyre well under rated power wise. But I was also trying to get a cheaper build cause like you I'm not very mechanically inclined either, lol.
