New engine gremlins - frustrating

IMHO, that cam is not going to be all that torquey at low RPM's. At 20 mph, and the TC locked, then engine would be turning around 2600 RPM, assuming a 3.55 rear gear so it is making sense that things are starting to work at that speed; the cam is getting up on the curve.

Got any piston info for the new engine? CR is unknown at this point.

Sorry, I don't have the paperwork with me, but I seem to remember Mike (MRL) saying the compression is little over 9.0
I am new to this with performance upgrades.. I just want to make sure the TC is good for what I have and not causing any additional problems. It's mainly a weekend cruiser. The rear gear is the stock 3.23

We are on the right path with the carb lean and the squirter upgrade? Just increase the discharge size.
