I don't think Ive put this story out there before, about a numbers matching shortblock I found for my car.
About 20 yrs ago I was dating a little minx whose father was an avid Chevy guy, and hotrodder.
My girlfriend was moving into his house as he had just recently remarried and moved out. On the 3 season porch he had a room full of car parts (along with a huge barn full of cars and trucks that would be super awesome to have that collection today!), anyhow in this room was a shortblock on an engine stand wrapped with a blanket. We were fixing up the house prior to her moving in, and I got snooping through the parts in the room. Found this engine and unwrapped it enough to see it was a SBC. Then I looked for the casting number...3782870...a 327, cool. Next I checked for a casting date, D 6 4...April 6 1964,

, my car was built on April 23, 1964. I think the savvy will see where I’m going with this.... next I checked the front pad, no VIN code, but the origin, date and application code shows F04I8R_...Flint April 18 R_ . 5 days before my car was assembled. The restorers say it needs to be at least 3 days before assembly, as the engines were assembled in Flint, and the cars were assembled in St. Louis. The blank after the R likley represents an unknown induction system, ignition system, and/or AC. The 365hp carbureted engine and the 375hp FI engines were identical except for the induction system. This block could be used for either by the R_code (but not for lower hp engines as it has the 11:1 pistons. 327 engines for 64 had several different R_ codes depending on hp, trans, ignition, AC, and camshaft used). So after deciphering the numbers, I figure this is a pretty legit numbers matching engine for my car (not to be confused with the original engine) which increases the value dramatically. The next time I see her dad I ask him if he’d consider selling that shortblock. So we talked about cars, trucks, engines, stories for over an hour, and he finally asks me why I’m interested in that engine, and I tell him its a matching numbers block for my car...he says, “thats a Corvette engine”, to which I replied, I have a 64 Corvette, well another hour later, he asks if I have a decent 350 or something to trade for it. I said the only thing decent I got not being used is a complete 396/325 out of a 68 Camaro....he lights up as much as I did when I found the shortblock! We trade and the engine has been in my basement for 20 yrs. now. It looks like a rebuilt shortblock, as the pistons show overbore, and the rods have been stamped with a punch. I need to freshen it up and preserve it. Still looking for number matching heads. Double hump 461 castings dated February to April 1964.
Corvette restoration experts (NCRS) say not having a VIN stamping and the missing blank after the R code would cost a few points, but I’ll never go that route anyway, and the one and only original engine is who knows where, so this is as close to original as I’ll ever get for the engine.
Some pics...
EDIT...
well someone burst my bubble....lol.
It has been brought to my attention that this engine was probably installed in a Chevrolet full size car originally with a 250-300hp application by the single R code and no VIN. Although the numbers for casting and build would be correct for my car, the single R indicates otherwise. All these years I thought I was onto what I thought was a needle in a haystack find.
