AA/Paul,

You're welcome. Post the numbers that you find. Also, if the engine turns out to be what the owner claims, then I might know somebody in Coloroado Springs who could be interested.

D3VE's are the most common production head of the carbuetted 429/460 engines.  Most all of them came with cavernous dished pistons beneath them and had a measely 7.9:1 c/r, which I'll bet the above engine has...it's a dime-a-dozen 460, not a CJ engine.  But being that it's in a boat, it may very well have the D0OE-9425-C iron CJ intake manifold if it is indeed the original issue 460 marine engine.

I cannot locate an SCJ vs. D3VE picture, but here is an SCJ vs. BBC 820 picture (the BBC 820 ports are about the same size as the D3VE ports):

I've bought more than 10 in the last year, $800 - $1200 for a runner, only if it has a Berkeley pump, would be a typical "steal" price. If it has anything other than a Berkeley pump, $300 - $700.
