Well I'm back at it again, I gave up on putting the muncie onto the lm7 I've got 2 good auto transmissions a th350 and a 700r4. I was told I would need a pilot bushing? From my torque converter to crankshaft to make up for the extra space anyone have a suggestion or any expierience with this thanks.

I run a 700r4, and a TCI flexplate. The TCI came with the spacer needed to run the 700R4 torque converter, and bolted right up no problem.
There is also a GM part number for the required spacer, should turn up with a search

Ok cool I'll look into that thanks. Have you built up the 700 at all? Im concerned about it handling the ls.

speedway motors sells the spacer for 19.99 that drives into the end of the crankshaft to use the dished flywheel.

I was told by an old transmission guy that the 700 was much stronger than the 350. In order to make a choice there are several questions to ask. What is your rear gear ratio? I would say about 3.5:1 (or higher numbers) for an overdrive transmission. Second, do you plan on long distance or in town. Love the overdrive.

A bit of both worlds really but long distance is the priority. The diff is currently 3.08. I'm driving the car now with the orig 350 pont 2 speed powerglide, I don't mind the 2 speed as much as I thought I would so here's another one in the mix u can get a chev powerglide also, which I'm leaning towards a little more for ease of installation. On the hwy I don't think it matters what tranny I pick ultimately cause all have a 1:1 final drive I do believe? Help is greatly appreciated.

TH350 is similar in strength to the 700. The 700 has an overdrive so final ratio is .70:1. For a street cruiser with limited highway, go with the TH350. For a highway cruiser go with the 700

Ok cool I didn't know that, thanks. Prob go with the 700 then, just need to find the spacer for between the flex plate and converter anyone have a parts # by chance? Just out of curiosity do you know the final drive of a power glide?
