ATI PG thoughts?
Looking to shift from my Art Carr TH400 to a PG and was looking at ATI and wondering what the thoughts on them were. I am installing a 632 BBC that made 1043 hp and 850 ft lbs trq on the dyno. I am looking at their High Impact Pro Glide to allow room for improvement. ATI Powerglide - High Impact Pro GlideŽ Drag Racing Transmission (atiracing.com) but like everyone I want reliability and sustainability.

Re: ATI PG thoughts?
My PG is still an OEM case and majority of the internals are still OEM. There are a few aftermarket parts inside to replace the parts that normally break but I still run OEM 1.76 gears even though some 1.80 straight cut would be better. I could easily spend $5000 for an all out aftermarket PG capable of working with 2000 HP but until mine breaks, I don't need it.
With transmission and torque converters, you really do get what you pay for. Inexpensive parts are not quality parts. Expect to pay around $1000 for a converter to match the engines powerband. The dyno chart will make picking the correct stall a lot easier.
With a high torque engine for drag racing, a multi speed transmission is not really required. You'll have more than enough torque to get you off the line with the first gear of a PG no matter what the ratio and with only one shift, it improves consistency.
