Need help with casting numbers
 

Hi,
I'm brand new to the forum and hope I'm posting this in the correct place. I need help deciphering casting numbers on a motor. We rebuild vintage boats and recently purchased a 1960 Span America. After close inspection we've decided the hull is beyond repair so we're now trying to figure out the value of the motor and if it would be useful in a vintage car. Here's what I know:

Block casting number: 3858174
Number stamped in flange: F0II7HT
Aluminum Intake manifold: 3890490
Head Casting number: 3782461

One valve cover has a sticker on it that reads (as close as I can tell) "Number 1 Team" and then below that: "Chevrolet Tonawanda"

Thanks in advance for any help you can provide.

Welcome to the forum.

May be a BBC. Might post this in the Corvette section also.
