After spending several months with the frame, striping, sandblasting, painting, power brakes I finally mounted the cab today and did a test motor installation.
I have a 01 LS1 motor with a 4L60E trans with 47K miles.
Here's what needed;
Motor mounts - Modify or buy S&P type plates
Trans mounts - Purchase needed, where to get it?
Notching the K-Member for Compressor and Oil pan clearance
Modifying the MAC headers or get new one.
Get wiring harness and PCM work done - Getting this done in the upcoming week.
I'm starting to feel a lot better now that I've actually put the motor in for the first time.
