Would the converter balloon even at lower rpm like 2000 to 3000rpm? Btw this engine is in my 86 Ram W250 right now. Built it to be a pump gas motor with good street manners. The idea was to run it in my truck until i get the old worn out 360 freshened up, then this spring, replace the cam with the 484" mopar hyd cam and a Performer Rpm to put in my 69 swinger to replace the 30yo solid lifter 340 so its a little more street friendly. 11..1 comp, mech cam and having to run leaded race fuel isnt as much fun as it used to be. Figured with the 4 speed and 4.88 gear, even a milder motor is still gonna be fun to drive, especially runing pump gas and not having to worry about lash adjustments.
