Helllo, I just got a 69 350 cast#3956618. Yes i'm sure it's a 350 2-bolt main also. This is what puzzles me the rpo# is HV. T0331HV. Not complaining about motor just wondering why it was stamped HV. My book shows that to be a 65 327. And it's not. Any insight would be greatly appreciated

looks like that code was used for 327s and 350s.

It appears like it could be a large journal 327 or a 350.,. 327 stroke is 3.25" and 350 is 3.48"

Thanks for the feedback. It's defintely a 350. Done tore motor down. That's main reason i bought it. I ran suffix HV 65 327 vette motor. Just gave $200 for whole motor. Got it home ran cast# came back 69-79 350. It's got partial vin# it is a 69 model and the car was built at Doraville. Any ideas what kind of cars where built at Doraville. What get's me the cast#'s  come back that it is a 4 bolt main and it's not. Regardless it's a damn good engine to build. Been meaning to go back to the salvage yard and run more #'s. Guy will tell you he hasn't got any good motors left but damn they'll interchange for 40 years.

Here is what I have.

Engine block P/N 3956618 shows this in my book. 302 1968 4 Bolt Z28
                                              327 1968-69 2 Bolt
                                              350   1969 2 or 4 bolt
Now the only thing that this proves the block is a 4" Bore, and is probably a large journal.

Now I'm going to through a wrench in the gears.
Your Engine Code #T0331HV deciefers like this.

T=Tonawanda engine build plant

03= Feb 3,

HV=1965 327 H/P hydraulic lifters. A/C, Manual/Transmission

The rest is this 350 Horse Power, 4BBL,Vette.

Thats what my info shows.

Do you have any idea what this engine came out of....That will help.

What I remember of that year 350/327. It was a nasty freaking engine. The 350 horse power 327 was an engine to recon with I'll tell you.

It was also in the 1966 ChevyII. I ran against those on the street and there was one that was all redone with a solid roller cam, balanced and blue printed etc,etc, etc.
  I wasted the Tri-Power Goats. I had to give the 4BBL goats 6 cars in,and still wasted them. But the 350/327 was one nasty SOB. They had better heads, a bigger cam, and a freerer flowing exhuast. The Vettes had options of side pipes, and of course they were lighter. That engine had that nice Rumpity Rump lopey Idle we all like. There's nothing complicated about the cam either. it was .447/.447 .222/.222 that was GM's specs. You'll see Crane and Comp Cams have similar specs.
  You can get them to work with an automatic trans. You'll need atleast a 2500 stall convertor.
  My sone and I did a 350 for his 86 Monte Carlo SS. When we were done it was a nasty SOB. Thats when guys were saying there's better cams then that. I know there is, but this was a perfect combination.

In 1965 I had a 19641/2 Mustang K Code, that was the HiPo 271/289. I purchased it from a guy that had more money then brains. He sent it to Tasca Ford in Rhode Island. It will take too long to tell you what was done. I still have the list.

It came out of a 69 Impala. I thought someone had stuck that 327 in it and used topend of 69 model motor the car is 40 +. I disassembled and cleaned whole engine. Even used chalk over suffix pad thinking it might have been a HM. The guy junked the car or i would check partial vin to vin on the car.

Your right the Vin would have given you some answers. We can chase those numbers and keep coming up with different variations. I'll do some more research but can't promiss anything. At least you have some information.
 Do you have the head numbers. That will tell us if the heads are the same circa or not.

The head #'s are 3923441 and are also date coded 69. I have a smallblock id book. I ran #`s on everything from exhaust manifold's,intake, crank. Everything is date coded 69. The cast # on block are never wrong.That's what puzzles me the suffix code pre-dates the cast #. Hell if i know. Still a hell of a motor to build. Was going to run a set of vortec heads(have 2 set's). Thinking of running a set of 67 3782561 heads , valves have been cut to 2.02/1.60. They say the vortec will out perform but with the HV and the heads.I could fool a lot of people.
