LOOKIN FOR PISTONS (318)

A stoker kit for a 318 is going to run you about $2K. If it was me, I'd keep the stock stroke and use the KB167's, put 1.88/1.60 valves in the heads and have them pocket ported/bowl blended and a Comp Cams 268H or something similar from Howard's Cams. If you know for sure you want a stroker, a 360 kit is quite a bit cheaper than the 318 kit (at least the ones I could find) so it would be almost as cheap to find a decent 360 core and build that - plus you'd get the better flowing 360 heads and a few more cubic inches.
