This, while very nice in theory is NOT as easy in real life, at least if you want a long lived, reliable motor. I have, right now, as i speak, every single part needed to make a seriously badazz stroker in the loft of my barn. Even with $2000 to throw at it and all the parts, i could'nt afford to build it. I really REALLY wanted to do a stroker, but the cost of the machine work is simply to much and with no job and no income i don't have many options.
I will probably snag a cheap 4.0 out of the junkyard for the time being just the truck can move under its own power once again. I contacted the place i will get the engine from and they said there is a 30 day garuntte, exchange or store credit. I also asked about the state of the engines when they buy the car/trucks, they said if its has "good engine" written on the windshield, the motor was in good running condition when bought. The only thing they do after purchase is to drain the fluids, and put it in the yard.
