I'm painting the engine now, so I will be putting the Procharger on in the next few days. I will be glad to post some pics when I install it. It may take a few days though.

I can say with 100% confidence that you should stay away from supercharging this engine. I've tried to supercharge these engines twice, and both times, it's been a disasater. I've been SC'ing and calibrating engines for awhile, but I will not touch one of these again, thats why we don't offer a kit. The last one, burned a hole in 1 piston, at 2" of vacuum!! Never got into boost. Extremely sensitive to timing, the cylinder head has a very sharp point, directly in the center, once this gets too hot, piston go bye bye.
