distributor drive

What motor you using and cubic inches
505" wedge w/ raised port heads, solid roller , 727, 3;73 / dana 60 w/ Detroit locker, 1200 cfm fuel inj. system.
Going to put a 5800 gov. in the trans next, then maybe mini tub it--------------Don't get around to doing too much in cold weather, and being 72 yrs. old !
Am thinking I still have some rings that aren`t seated-------------2 runs down the quarter, and a little hot rodding on the street, w/ about 500ish (guessing) miles, you`d think they would be seated ! Doesn`t seem to have any blow by to speak of tho.
