I ran the old MP 175 and it was a good converter, but as I got more into the drag racing scene. I went with PTC.

I hae been tickled pink with them. I have bought three converters from them.

I currently run 3200stall 10" in my Dodge, and it works well, tight when around town, but flashes about 4400, when I get squirrly!

I also have ran one of their 9.5 converters on my old 1970 Dodge and it was a 4200 stall and people couldn't beleive how well it drove on the street.
