Tech, I fell the same way. He lives right next door to where I work and I look at the engine and found the rochester carb that was on had only 1 bolt holding it to the intake. The radiator is for the stock?(6 or 4) that came with the truck. The radiator hose was completely flat(no water getting to the engine) the intake I took my torque wrench to and found the first 2 bolts were loose and that is when he told me(I'll do it myself) so I know he hasn't done a damn thing with the intake gasket. I really think his problem is either the intake is warped or the gasket moved when putting it on. Believe it or not the engine sounds great, no rod noises to make you believe the bottom end is bad. Just smokes like crazy.
