I built one last year for the shootout---I won fastest stock appearing with it.
I used a stock truck crank, stock SC rods, and a set of replacement hypereutetic pistons for a 98 mustang 3.8 V6.---Yeah I took the cheap route but I knew with the stock MAF, throttle body, and M90 I wouldn't be straining anything. I managed to run a 13.82 with a single intercooler and only making about 9 1/2 pounds of boost.--That was on a set of worn out 225/60/16 el cheapo tires too.
I am currently redoing the engine to pull a bit of compression out of it since doing what I did made about 9.4 to 1 compression. I am going to have a bit of a dish machined into the top of the pistons, also I had to have .200 cut off the center counterweights on the crank to clear the piston skirts because I used the stock SC rods.
I did manage to build the engine for about 1400 bucks so bang for the buck was pretty high.................Dan
