Im going from a 1 piece main seal 305 to a 2 piece 350. Had a centerforce clutch on the 305, I would like to keep the same clutch and starter, will this flywheel work? Im 99.9% sure it will just wanted to double check before I order it. http://store.summitracing.com/partde...N=700+&FROM=MG

 

Yep, that's what you need.
Hopefully your 350 has the two inline bolts drilled, otherwise you'll need to have the inner one drilled and tapped.

 

whats the inline holes so i can check before i put the crank back in? kind of off topic but the 350 harmoic balancer looks bigger can i use the 305 one so i could run my old serpentine set up from the 305?

 

He's talking about the starter mount bolt holes.

You should be able to use either damper. No more than they cost, you might want to consider a new damper for a 350 serpentine application.
