RE: [Chevelle-List] Engine code

I checked both casting numbers at http://www.mortec.com and came up empty with .  When you say block code and head code, I assume you're referring to the casting numbers?   I remember reading here or on TC that sometimes the engine plants would stamp the additional "H" on Holley equipped engines as an identifier.  The only "HC" code I can find for Chevelles is a 69 350-2  L65 engine w/standard trans.  I have a Chilton's Manual that shows the "HC" code for 65-69 327 Chevrolet full size and Corvette but it's with a PG and NOT the high performance model.  What is the rest of the engine number stamped on the front pad?   I wonder if this is his engine or "he's selling it for a friend" and doesn't really know anything about it?  Sounds like it's akin to all the 396/375hp and LS6 engines out there...more than the General ever produced.  I don't show a 66 327/350 engine (L79) for a 66 model, and can't find a listing for any in any books I have or on TC - were any 66 L79's built?   With an engine date of July 9, 1966, that's pretty late in the model year - you must have a very late production 66.   Dale McIntosh TC Gold #92/ACES #1709 67SS/67 Elky Dale’s Place – My 67 SS and 67 El Camino ChevelleStuff – Decoding info on 64-72 Chevelles Team 67 – 1967 Chevelle/El Camino Specific Midwest Chevelles – Midwest Chevelle Show Information -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of R Milkiewicz Sent: Sunday, March 09, 2003 2:27 PM To: Chevelle List Subject: [Chevelle-List] Engine code I'm looking at a 327 engine to buy. The seller says it's a 327/350. The block code is 3968174 and the heads are 3860462. I can't find these numbers anywhere. The deck is stamped HCH. I can find HC but not HCH. I haven't looked at the motor yet. This is info he gave me over the phone. If it is a 327/350 it will be mine. He's asking $1500 or best. Can anyone one help me with the casting numbers? Mfg date on it is 7/9/1966. Correct for my '66. Thanks Rich
