Cam Centerline questions

Also check into PTC. I don't know a whole lot about them other than a friend runs one in his pro mod car and recommended it. Their 9.5" is $475. That seems cheap so I'm a little weary of that. But Tim at PTC did say it's a billet front with furnace brazed fins, etc which some other companies do not do and charge more for a similar converter. So it did sound like it was a quality unit.
