th350 to a gen3 ls
question, im swapping out a small block chev for a 1999 4.8 and will be running a th350.. now from what I understand is that I need a flex plate spacer which I have found through summit......... does spacing the flexplate back affect the alignment of the starter on the flexplate as far as how well the teeth mesh up? maybe im missing something but seems like it would be an issue?
thanks much guys

I dont think you will need anything if the engine came with the flexplate. I put a th350 behind my ls1 and had to go to junkyard to buy a flexplate off of a truck motor. The correct flexplate has the spacing in it. It will have an offset. Earlier style flexplates were flat. That wont work

I'm doing an 99 4.8 out of a truck to a turbo 350...... I'm wondering if my LS is different. From what I can tell there calling the 4.8 is a gen III. Not sure if that's correct, I'm new to the LS scene.
Summit is selling a spacer for gen III LS to a th350/400 700r4.

ls1 is an all aluminum 5.7, ls2 all aluminum 6.0, ls3 all aluminum 6.2
the 4.8 and 5.3 are the hottest thing going right now in terms of conversions. They are cheap, make hella power, tons of aftermarket support, reliable, efficient, etc
most people just refer to all gm v8's from 97 and up as ls motors. Now you have lt1's which in my mind are still ls motors because the most previous lt1's from 92-97 were still based on the sbc
