Replacement Cam

Don't know this company, but...

If your not worried about sound, this looks like a hell of a deal.

Melling MTD-1 | Engine Camshaft (Vehicle Custom Fit)
parts hawk is a reputable seller, they're just a big online middle man like rock or whoever.

melling is good stuff and great value.

that cam is bascally a 340 cam, but it's ground on a 112. i've run them in 318's a bunch. i think there's better, more modern, or more suitable grinds out there for this application, but they're also more money.
