Mainly just want to run down the interstate at 70mph comfortably. Right now I have trouble maintaining 62mph at redline of 3,600 rpm. The transmission was originally a five speed with single speed rear end. The previous owner switched to a 4-speed with two speed rear. The Y-Block runs smooth, and only used a little over one quart of oil on an 800 mile trip from St. Louis to Houston.
I've thought about electronic ingnition, aluminum intake, etc. to pump the power up. Mainly it suffer from very little torque.
