351W piston I.D.
Can anyone tell me the name of an aftermarket piston for a 351W with the letters SD 11-12 cast into the underside of the top? I haven't removed them, but they appear to be aluminum. The engine has extreamly little run time on it and had been fogged B-4 storage for several years since it was professionally built at a local speedshop.
I inherited this engine and would like to determine to what extent it was built. It's new clean inside of it. and has the following performance parts.
* Holly double pumper w/manual secondaries
* Edlebrock Victor Jr intake
* Mallory Pro Comp 9000 mech advance distributor & Morosso plug wires
* World products Windsor C.I. heads (valve sizes unknown)
* Roller rockers & guides, Hyd non roller lifters
* Cam (could see K1 at tail end lobe) specs & mfge unknown
* Crank HI PO 21268 cast into front through weight, WG840 about center of the crank on the through weight
* Rod had 504.0, 184.2 on each of the caps
* Pistons had PWP 775.0 etched into the bottom of the skirt
Help with any of the above would be greatly appreciated.
Thanks,
