I have worked on this thing a good bit and have it running decent and drivability is good, the blower is making about 8 psi at 5500. The issue Im having is on the 2-3 gear change, rpms drop to about 3300 and its real slow getting back up to spin the blower fast enough to make power to accelerate. iths like it hits a wall at about 85mph. it has 37" tires on it so that is certainly an issue. Im not sure if the converter is locking at WOT in third, I made some changes that I thought would correct it but it is still sluggish. Any help is greatly appreciated.
