How did you pick your torque converter?

I just called PTC (http://www.ptcrace.com/) and chatted with them for a while. Very friendly and informative...they quoted me $475 + shipping for a 9.5" converter with a 3500 stall. Not too bad, I guess...

Does that diameter sound correct for a 904/stock flex plate?

They wanted to know the cam specifications...this is a dilemma since I plan to swap out the stock Magnum cam next year for something more wild....so what do you guys think: will I have to re-buy this thing next year?

I'm amazed at how much I have yet to learn about thse cars. I have been drooling over classic muscle cars since I was old enough to drool...but this is my first time actually putting one together so I feel like I have been starting from scratch!! :D


I think you'll be OK. I'm running a 9.5" converter that stalls around 3500-3800 with a Magnum 390 and a big *** cam. I'm also running 11:1 compression too, so that picks the bottom end back up a lot.
