Information on Race Parts please, stuff from the late Chuck Forge Options

[carl k]

Hi all-

I recently wound up with some ex-race spare parts that belonged to Chuck Forge (Chuck's 914 for sale). From what I've read, Chucks' car was very quick.

I'm more of a "stock engine" guy and don't know much about performance mods. I'd appreciate any feedback on these parts, such as if they are trick or kook, how specialized they are, value, applications, etc. If I knew more about them, I'd feel more comfortable trying to find them new home.

The heads look like 1.8L heads, 38 x 48 valves, double valve springs, with a deep relief for the cylinders. They've got some sort of thermocouples where the CHT would normally be. Exhaust ports have been machined oval to accommodate the matching exhaust stubs.

Pistons are 94mm Mahle's with a pretty good crown to them and valve reliefs cut into the tops. There's a part number printed on the cylinder base "24 503 WR 10". The cylinder tops have ridges to seal better against the head.

The header is a 4-1 style with 41mm ID primaries. It looks like the muffler is a recent addition as it's only tacked on, and there's a short intermediate adapter. The four primaries are a slip fit into the collector. The headers use separate exhaust stubs that fit the round ports found on the head. All the welds look like TIG, and it's carbon steel. I am not 100% sure the header is specifically designed for use with these heads, but the stub adapters match the headers.


thanks in advance,
Carl
