Pulled the worn out 6.5 out of o 94 suburban, putting in my trusty 6.2 out of My old 85. The 6.5 leaked everywhere and blew more smoke from the dipstick than the tailpipe. The 6.2 is solid. I've had it for 10 years. Replaced the db2 once.otherwise it's been flawless. We'll see how it likes the turbo. I've been following the ds4 to db2 conversion bible it's very good but, I'm having a hard time finding the correct wires for the cruise control. Other than that I'm almost ready to stuff it in the car.
