I’m putting a powerglide behind my 440 in 69 dart, while I’m at it I’m going to go ahead and throw a mid plate in it. I’ll be running an ultra bell, with a fti converter. I’ll be having a custom drive shaft made. My questions are what is the best flex plate to run, where is the best place to get a crossmember that will fit this, and what else will be needed to do this swap?
is this still in the planning stages? if so then a common swap is a th400 behind motors of most any make. they're cheap (er) to build a stout 'box compared to others too which may be why they're so popular.
neil.
