If the suffix codes are not correct for your 66 (and,
since there were no L79s that I or anyone else can find), the date code is
a kind of a moot point isn't it? Not arguing, just asking <g>.
Whether he "looked" up the numbers or not, I'd want to tear the engine apart and
find out what heads, what cam/lifters, etc. are used. The 327/350 also
probably had a different intake and carb than are on it now - just guessing
here. So to say it's a "350hp" engine is sort of a guess. It's like
all the LS-6 powered cars out there with different cams, roller rockers,
Edelbrock intakes and Edelbrock or Holley carbs, etc. It may have about
the same equipment as the LS6, but to say it is one is kind of
fudging.
What I'm saying is, if it doesn't have the original (or GM
equivalent) parts in it and on it, it's not a 327/350 anymore. If it's
coded "HCH" it might be worth something to a Corvette or Impala guy to be
"correct".

Dale, I haven't seen the engine yet. The guy went
out of town this week and will be back next week. I plan to go and look at it
and take all my casting info with me. I guess saying "correct for my car"
isn't correct. I should have said, same year as my Chevelle. I asked him how
he was sure it was a 327/350? I thought maybe he was the original owner. But
he wasn't. He said he looked the numbers up. I have to go and look at the
block myself. If it's not what he say's, it sure isn't worth
$1500.

Subject: 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.

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
