Default Does This Seem Do-able?

Here in a few months I plan on swapping my '88s L98 out for a GM ZZ4. But the thing is Ive never done an engine swap before.
Though I really want to do this one. I will be doing it at this auto shop on base. Im going with the longblock and for now I'll most likely use the TPI though I might get new injectors. Ive been reading up on the engine and swap. Does anyone have experiance with this particular swap?-anyone done this is their 1st swap? Any problems I might run into?

Check how the new motor is balanced. Internal/external, depending on your transmission(manual/auto).

Pretty sure I read that the ZZ4s are internally balanced. And my '88 has the 4+3.

Default ZZ4 install

I had Exotic Muscle in Tempe, AZ replace the engine in my 1990 with a ZZ4 crate motor. No problems with the install. Then added a Pete auto trans, torque converter & 3:73's. I'm very pleased. Have Jesse. Ski_down_it burn a chip for your set-up. Good luck.
