Well I have an update after putting 1500 miles on it.
The new engine runs good. But it seems to lack some of the low end grunt that I want. It takes a bit of RPM and throttle to get it moving. And seems to always need a lot of throttle to keep it moving up hills. It seems that it sometimes has trouble getting into OD while cruising. Is this a product of my cam, torque converter, gears, maybe all three? It is fast from 3k RPM and up.
