converter

I agree. Give PTC a call.

I have a 2001 5.9 Magnum stock bottom end, aluminum 2.02 heads, mild cam (.215/.223 @ .050, .517 lift), Doug's headers, Air Gap and 650 AVS. 904 and 3:55's.

Filled out the spec sheet on the PTC website, then called and talked to them. Got their 9.5" converter. It flashes around 3500, but runs great around town..I forget it's a stall converter when driving around town.

Drove around town for over an hour yesterday. Only hammered it once since the wife was with me!!
