I'll admit, up until a few days ago I didn't know what a Powerglide was really was, other than they were popular with the drag racing crowd.
As I work on my Neon I'm planning out my Maverick build which will include a turbo LS (goal of ~600hp +/-). I've been eyeballing the "Pro Street" C4 by Performance Automatic which seems like it would get the job done and fit like stock (because the car has a c4 currently herp derp). It can be made to work with an off the shelf adapter bellhousing and a custom torque converter. Its $1800 but rated at 750hp and has a lifetime warranty. (Building my own c4 myself is also an option to save some dough)
But recently I was eyeballing the th400 which would work great but is huge, then the th350 which doesn't seem to be any stronger than a c4 and finally the Powerglide. It seems like guys with big power are making them work and they are fairly streetable, maybe I'd keep the rear end gears around a 3.20. You lose a gear but gain about 10whp across the board vs the c4. And even if the c4 has a warranty, it'll still be a huge pita if it breaks. I think most would say a well built PG would be stronger. If anything the PG is smaller too. WWCSI do?
Scott, I have the Neon(s) I wanna row gears. I kinda like the idea of the auto for the Mav, in fact the PA "Pro Street" is still fully auto even though it handles 750hp (probably why its $500/more than the fully manual version) I do want to do a lot street driving, supposedly guys are doing just fine with PG's but maybe I should just stick with the C4 (KISS). Keeping the shifter on the column will help keep a sleeper status too, bonus. I'll waiver 5 times until I have it put together. lol

I don't see the benefit of keeping a C4 behind ellis other than it's a ford trans in a ford car. For simplicity I would think a GM glide, three speed, or 4L80E would be better suited for ellis. I picked up a 4L80E for $700 from a junk yard, pulled and put on my trailer by the yard.
