This car is for sale and claims it is a 312 engine, but several things make me question that.  The heads have sand core plugs/freeze plugs in the ends, an aftermarket intake manifold and carburetor, and headers.  I was under the impression the freeze plugs were pre-56, which would preclude this being a true 312.  Is that correct?  I went to Mummert's site and I  have printed off the block numbers, head numbers, crank identifying dot, etc., but if this is bogus, then the price is way too much for this car.  Any ideas would be appreciated.  Thanks, Joe-JDC
