Default Motor swap

I am getting ready to swap motors in my '80 and want some practical advice. I've done plenty of motor changes in other cars but not any Vettes. I don't want to pull it with the transmission (auto) if I don't have to. Basically I don't feel like unbolting all of that just to put it right back. The trans seems to work fine, but I am putting in a new torque converter since I'm there. However, if you all think it is easier to pull the motor with the trans attatched I will probably go that route. Thanks

I just had mine done. The trans stayed. Even the radiator and hood stayed. Like I said I had it done. But the mechanic didn`t have any trouble doing it like that.

I've pulled the motor only. You need to remove the hood. Also most engine hoists aren't long enough to reach from the front of the car so you will need to put it in from the side.

he pulled the motor without removing the hood? that's amazing!

I've always pulled the motor sans transmission, the only real challenge is getting to the bellhousing bolts that mate to the rear of the engine block.

I have always pulled the engine and trans together for the following reasons:

The whole Bellhousing/torque converter/starter assembly is much easier to assemble properly and test outside of the car.

It's a good opportunity to inspect the trans, cooling lines, modulator valve, trans mount, drive shaft u-joints..you get the picture..and replace anything thats not up to snuff....nothing worse than getting a new powerful motor in, and breaking something in the DT soon after.

It come's down to personal choice of course, and how much time and effort you want to put into it. Just remember, being proactive now might save you a tow and frustration later.

I bought a GMPP 350/330 horse crate engine with the Vortec heads. At $2399 it seemed like a good deal. They put a Summit store about 50 minutes from my house so an easy pickup. I will try and post some pics of the swap etc.

I agree on that perspective, and thats what I did with my '69 Camaro. I swear though, that thing is easier to work on! I'm sort of being on the cheap side right now too, which might bite me in the A$$ later. When I scrape together the coin, I may yank the trans during the winter and have it gone through if I don't destroy it with the new engine. For the most part though, the trans seems to work perfectly. Shifts fine, no noise, fluid looks good etc. The drive shaft u-joints I just replaced, and admittedly, taking the straps off the rear one was a PITA. One day I'm going to actually buy something I don't have to work on!!

Excellent Choice...for $$ to HP you can't beat it. I have a friend who put that one in his 69 Chevelle in 99 and it runs strong!
