Will a 1 piece main seal flywheel bolt to a 2 piece main crank?

IE: 91 Flywheel bolting to a 79 Crank?

If not, what flywheel do I use?

I'm the kinda guy you bring home to Mother.

 

Nope sure wont. The 86 up flange is a smaller bolt circle, and it has a counter balance weight. If it is a 350 you need to get a early model 2 piece neutral balance flywheel. If your using a t5 make sure to get a 153 tooth. the 168 will not fit in the bellhousing.

true, the 1 peice rear main seal flexplates will not bolt to a 2 peice rear main seal motor. If you are using an older block (2 peice rear main motor) then you will need to use a 305 flexplate and starter on it. I just went through this with my wifes car and let me tell you it was a nightmair. I ended up haveing to put an after market minni starter on the car just because i didn't knwo that these cars only had the small 305 flexplates on them. Don't make the same mistake I did.

 

I found the solution, an 83 LG4 flywheel, 153 tooth, 12 3/4" diameter 3 5/8" bolt pattern like the 79 350

Looks like I may have a 350 in the RS sooner than planned....
