If I were to do the swap (4bt) into a 91' ... 1) need a new trans? a) because the 91 is computer controled b) or because of the RPM's of a diesel c) or could I keep the trans (upgraded) and use a new (lowerstall) converter 2) Is the current engine, 350tbi, controlled seprately from the trans? 3) Can I still use the 241 TC, in order to keep the VSS (speedo, right?) 4) What could I expect for a top speed with 3.73 gears and overdrive? 5) would I have to change my gauges because I wont be using the TBI fuel tank or sending unit? Thank you.
