I just saw an advertisement for a 95 1/2 ton 2 wheel drive P/U for sale locally for $700, 130K and supposed to run good. The ad got me thinking that it would be the simplest way to improve compression, efficiency, and general street manors... It seems to me that the engine and transmission could be swapped as one, and get an updated drivetrain w/out the hassle and added expense of finding bits and pieces here and there. To do the job, it seems that a timing cover, oil pan, Intake, and electronic fuel pump would handle most of the engine side of the swap... and figuring out how to control the overdrive, and converter lock up, would be take care of most of the transmission puzzle... Then to source a rear end that has something like a 3.55 or 3.73 gear ratio... What are your reactions to this line of thinking. Am I nuts to wonder if it is the easy and economical way to add 100 HP/100 LB-Ft?
