Everything on the motor will swap out, but the I think the motor mounts are different

[Blazin]

Fly wheel on the 4.3 is a one piece isn't it. 79 would be a two piece?

[Captkaos]

Hmmm I think your right Blazin.

[hilton850]

is the 4.3 internal balance or external balance? 
Blazin, do you mean external balance when you say 2 piece flywheel?

[VileZambonie]

He means 2 piece rear main seal not 2 piece flywheel

ok thanks  guyes hear is one thing tho the guy wants bothe my 4.3 mortors an iv got a 389 out of a 66 catlina with a 2 speed powerglide behind it  most of it is junk but the power glide works fine any one know what the power glide is worth?

I sold a glide last year that had been outside for two years. Turned it over, dumped the water out of it and sold it to a guy for $100. He watched me do all of this but wanted it anyways.

Look for a speed shop or dragstrip/swapmeet to unload the glide. They are only good for resto or racing really.
