Here's the deal. I gathered parts to build the NP435/203 doubler. I needed to pull the tranny to have the main shaft cut and resplined. So as the back up plan I pulled the C4 from my parts rig and rebuilt it for duty in my trail rig. I let a pal of mine talk me into using a step-up from stock torque convertor(1600-1800). With the rig idling in gear with the brakes on, I can flash the convertor to about 1800-2000 on my cheap-o tach. Just as advertised. My peeve is that when I'm cruising at say 2200 rpm in high(without a detent) and mat the throttle it is flashing to 3K. My engine makes great low end torque and I believe it is blowing threw the convertor. It just feels weak to me. Maybe I should have just went with a stock one.
