Hi guy's 54blackhornet here up in Northeast Oregon looking for some help
with my 68 GMC 1500 custom wide LWB.Gold with white roof, it is a 59000 original mile survivor.
I replaced the 250 with a 89 mexico block 292 bored 30 over, but the stock 3spd just does not work well with the extra torque of the 292! Can anyone suggest what trans i should try ? I would like to keep the three on the tree so as not to cut the virgin low hump floor.Also I would like to see some more threads from the stock 6cyl fans! come on with gas around $4.00 I know you are out there!
