Its a 3.75 i believe with 26 OD. I tried shifting into od at 45 and 50 all the way up to 55. 3 low cruises all the way up to 55 no problem then i shift into OD and it drops to 50 ish and wont accelerate unless im on a decline. 2 high has no problem accelerating. I tried timing at o advance at idle as well as timing from full advance with 25 and 28 degrees. Im stumped.
