I've got a 410 out in the shop, but it's bored .060 over to be nearly a 428. It ran well, and did use the 1U crankshaft found in the 428 engine. This one had the C8AE-H heads, ID'd as either 390 GT or 428 depending on who you talk to. Big valves - close to the C8OE-N heads that are on the car now. Also had a "S" code 390GT intake, and the free-flow 390GT exhaust manifolds when I pulled it from the Shelby.

I'd offer to sell the thing, just to get it out of my garage, but shipping from California would be brutal!
