Just got 4l80e out of donor truck. Good news its re-manufactured(GM),guess good. I knew converter pattern was 6 bolt where as 454 In Panel is three bolt. Question any reason that bolting to just the three will not work just fine? Same pattern for 3 as 454 flywheel and heck thousands out there with 3 bolts. Heck my FED with 1500 hp is bolted to flywheel with 3 7/16 bolts as is most drag cars.
