that sure looks awesome I have ben playing with the idea for a long time now.

Thank you! Actually wasn't an intentional build, the 350 sbc blew up on the highway, rod went through the block, block was trashed and I was "forced" to get a new motor. Figured if you're gonna have to do it, might as well do it right.

Wickd, did you have any problems with the oil pan fitting?? If so,what did you go with??

WICKD 81

Actually, I bought the LS3 Engine with the Muscle Car Oil Pan Kit from Jegs, Part# 809-19301326K and the Engine Controller which also came with the pedal, engine harness, controller, Mass Air Flow Meter and mounting boss.
The Oil Pan Kit itself is Part# 809-19212593 from Jegs. No fitment issues.

Thank you Clint for the reply... I have been thinking of doing the swap myself..... I don't want to sink another dime into the crossfire I have now..

WICKD 81

Anytime!

Looks good. What transmission do you have behind the LS3?

There's only one caveat to putting an LSX in your C3.....
It leads to other things

That biatch ought to scream!

My wife has the LS3 in her 2008. I can't even imagine that motor in my '81. Looks like a lot work to get her installed but it should be well worth it.

Oh yea. Just curious what rear end assembly are you using to take the extra HP and torque?

I have been doing a LS3 in conjunction of a frame off. Good luck...
