Re: Best late model engine for conversion?
My setup is a 1995 throttle body 350, with 4L60E it is practically a bolt in set up into these trucks. Yes you will have to spend time on sorting out the factory harness or there maybe an aftermarket harness to plug and play.
I did it myself with input from some conversion books out there mainly for the electrical harness setup.
Yes it is a time consumer and there are getting to be plenty of these trucks in the salvage yard to donate the complete setup into you truck. Shop around and you might get lucky and find a good low mileage one. Yes you'll spend some money to get it right, but IMO a lot less than doing a newer style gen 3 type engine.
I'm getting easily getting 17-18MPG can pull a sizeable load in OD and go down the highway unloaded at 1600 to 1700 RPM.
Next option is a throttle body 350, with a 700R4 less wiring problems but still a very good setup.
