Pete and all, The crank and rods would have no problem handling the blowers. They did not put out a huge amount of boost, if I recall right The blower on my E is limited to 5 pounds of boost. Forged pistons would be a good idea. Correct fuel ratio would be critical, as the otherwise stock engine in my E expired because of a burned piston. 300ly, Don Wayne and all: How do you put superchargers on a 10.1 to 1 compression ratio and not blow the bottom out of your engine? Did the supercharger option come with a lower compression ration motor? Pete Fitch ------------------------ Yahoo! Groups Sponsor ---------------------~--> Yahoo! Autos.
