engine swap Kevin (10/18/2004 12:26:14 AM)
Im considering the purchacse of an 85 740diesel. How much should I set
aside, to swap in a gas engine? What would be the best choice for a
swap?

Why? Why not just find a 740 with a gas engine and buy that. The cost
to do an engine swap will be far more than the car is worth. There may
be emmission issues that will make the car unable to be registared.

My wife drives a 1985 740 that we bought which was converted to a V6
Buick engine. Since the engine used was a Service Replacement Block
engine with no VIN we only need what was on the car in the first place,
i.e. no AIR, EGR or cat. A loophole to be sure. It has GM TBI and is
driveable and economical, if not like the diesel. We are extremely
happy with the car.
