Hey I saw your post on the swap from a 2.8 five speed to a 3.5 five speed, do I have to have the 3.5 fltwheel? And what about flashing the ecm, chevy house said they cannot flash it because it is not an original engine trans combo. I'm not too familiar with chevy engines, I've swapped a million supras and Chevrolet plays a way more complicated game.
