iam a auto tech so i think i can do this.just need any tips on any mods to body or frame or any thing that might be helpfull.it is a 93 modle motor.we will be keep the 700r4 trans with this change.thanks you for any help.i have read some on this so i know somethings that need to be changed.but please let me know what things that you had to do or know to do.

 

you have to notch the crossmember on the pass. side to make room for the a/c compressor. the mounts must be swapped around, and you have to use one of the new ones and one of the old, not sure which ones. wiring harness was a major PITA with VATS, but not impossible. custom p/s, a/c, and fuel lines. its not that hard, but its not a straight drop in either. good luck and take your time

I'm looking to do the same, ive had my stock 1987 z28 long enough.. time to push her a little harder.

 

I've done the exact same swap with a 93 lt1, I had many problems fabricating my power sterring lines and fuel lines, it was leaking all the time , I found some swedge lock fitting, it solved the problem, I had to get a 4th gen radiator to cool that beast but you can keep the old stock rad. Like texas said wiring is a real pita but I got something for you:

K is DK GRN and is the coolant temperature feed to instrument cluster.
J is DK GRN/WHT and is fuel pump replay control
H is empty.
G is DK GRN/WHT and is vehicle speed signal.
F is GRY and is fuel pump motor feed.
A is RED and is Alternator feed to instrument cluster.
B is TAN and is oil pressure feed to instrument cluster.
C is BRN and is oil level feed to instrument cluster.

on the mounts i was thinking that i would use the old mounts off the 305. if thats not the right way witch mount do i use from the lt1 and from the 305?i know that in some of the reading that ive done it gives a part number for the right side of the motor.called the dealer and they said the part number that i gave them from the hgsalavge swap.that the stock one from the 305 would work.please let me know more.we took the motor out last night.this is my buddys daily driver.we must have this done in a 2 weak time frame(he is using vacation time).i have been looking at pic of other installs and dont see the pcm.where are you people puting them at?

you can use the stock 305 motor mount, that's what I did, A little welding here and there, it should be fine...
for motor mount pictures go to:
www.hpsalvage.com --> swap tips and you will see [picutre about the cross member and about the motor mount

I did the swap in 8 days. average of 12 hours a day !!!and i was alone, I removed ethe drivetrain completly. By the way i'm 19... if you guys are 2 and you do know what you are doing it's doable in a week for sure ....all you need is some junk lying around to be able to work with any situations. My dad has like 2 cars is part in the garage, and 1 cube van full of scrap metal it was farely easy to find the parts I needed parts.

If I were you, i would go to GM dealer today & buy a 93 trottle cable , it took me 4 days to get one witch got me late in my project.

If you need picutes of anything , ask me ...my firend has a digital cam.

Just for your information the starter enable relay is located in the driver side kick panel and it's hidden in a rubber compound sticky sh*t. when you'll do your electronic you'll need to rewire that relay with your ECM
