PTC converters switches hands

My 418 vert is only 4900. It’s very likely 300-400 low, but at this point not gonna mess with getting it out and having it bumped up.
I have always figured about 300 above max torque is about right. It’s always worked for me using that.
Not sure where max torque would be on your’s. The cam is 254@ 50 on the intake?
I would guess peak torque wouldn’t be much over 5k, just guessing lol.
Maybe it will like 5800, worth a try. Have you ran the car yet the way it currently is configured?
Dyno shows peak torque at 5800. Yes I have run the car in both the quarter-mile and 1/8 mile. 6.63 @ 104 with a weak 1.52 60 foot. I appreciate the comparison with your set up, however, I am dealing with a very soft launch. My car leaves like a Yugo with a misfire. I attribute it to converter as well as a 1200 RPM drop on shifts. I’ve already tried everything else and everything continues to point to the converter.
