One of the greatest challenges faced by some enthusiasts during a project build is selecting something appropriate to slot into their classic’s engine bay. If you face that dilemma, this Chevrolet small-block V8 could be the ideal solution. The owner rebuilt the motor with an eye for fine details. However, since he is currently on what will be his final project build, this V8 is redundant. Therefore, he has decided to send the small block to a new home with someone who can put it to good use. He has listed the motor exclusively with us at Barn Finds.
The Casting Code for this V8 supports the owner’s claim that the motor started life as a 327 beneath the hood of a 1967 Camaro. However, much has changed in almost six decades, and all for the better. The owner stripped the V8, but retained the standard 4″ bore. He slotted in forged 302 pistons and swapped the original crankshaft for a small-journal 283 crank of 1967 vintage. This is essentially the same process Chevrolet used for the Camaro Z28’s motor, so, unsurprisingly, this V8 shares the same 302ci capacity. The owner scrutinized every aspect of the motor, leaving nothing to chance during the build. He installed a new oil pump, new bearings, freeze plugs, alternator, water pump, and a complete set of gaskets. A camshaft from Competition Cams should unleash plenty of ponies, especially with the V8 inhaling via a four-barrel carburetor atop a genuine GM aluminum intake. Spent gases exit through GM exhaust manifolds, making the 302 a turnkey proposition.
The engine stand can be purchased for an additional $1,000, and it is worth every penny. It would be an excellent addition to any workshop, allowing the buyer to test engines before bolting them under the hood. It is a good way to ensure everything is healthy before installation, because removing an engine due to an unknown fault can be both time-consuming and frustrating. This stand eliminates that possibility, and if you place a monetary value on your time, the investment in this stand is easily justified.
This Chevrolet 302ci small-block V8 is a sweet motor and would look at home under the hood of any Chevrolet classic from the 1960s. It will provide excellent performance without being highly-strung, and should offer decades of reliable service. The stand could be an excellent addition to any workshop, and would be a useful tool if you have multiple builds on the go and wish to test a motor before dropping it into an engine bay. Therefore, if you’re knee-deep in a build and haven’t selected the most appropriate way to power your new toy, this small-block makes perfect sense.

Was this engine machined for four bolt mains, or does it retain the two mains of the 327? Some more details about the engine would help any prospective buyers, like what carb, cam, compression, forged or cast bottom end. The heads look like 2.02 heads, you get the idea.
The carb is a Q-jet, date unknown, the intake is an OE unit from the late-1970’s and the heads are 1968 or earlier Camel Humps, most of which had 1.94/1.50 valves.

I think all the Z/28 302s were two bolt main, but they had special large journal crankshafts, not the small journal 283 versions. About the only thing ‘302’ here, compared to a Z/28 version, is the bore and stroke.
That said, these ‘home grown’ 302s will pull hard even with an automatic if outfitted properly with gears and a converter.
I had a 1969 Z/28 back in the 80’s and it had the original DZ block. It was 4 bolt main. If my memory serves me correctly, the 1967 302 was 2 bolt main, but the 68 & 69 were both 4 bolt main.
It is not a DZ designated engine. So the promenades is not there. it is a home made 301 as we all did back then. It is still worth something, but i dont know what the buy it number will be.
Some more information on the engine, sorry I should have mentioned some more details?

Tom, keep me posted on the engine stand l would be interested.
Will do, I would like to see both sell?
I have a Buick nailhead I would love to see on that stand as well but will build a stand for it if needed.
Thanks for the reply,
TomG
Forged, from a truck motor, Crankshaft? Just like a Z28!
When I was a kid, the thing to do was to bore a 283 out to 4”. Hence a 301.
The issues were varied, thin cylinder walls and over heating. I am far from an expert but this gets to the best of that world by having the bore to begin with and with 6” rods I would assume to gain some low end torque?I hope that my ignorance has not offended anyone with the knowledge that I assure you I lack.
Thanks for all your input and expertise.

Two Questions..Is there a reserve on the auction.? Is there shipping available.
There is a reserve and we can put you in touch with a broker but shipping is ultimately up to the buyer to arrange. Thanks and good luck!
Very interested in this engine run stand, with or without motor. Can the run stand be purchased separately depending on the outcome of the auction?
There are a lot of inaccurate statements above.
67 Z28 302 engines used the same 2-bolt main 3892657 block as the 67 350 and early 67 327 used. They are all small journal crank blocks.
The description states: “The Casting Code for this V8 supports the owner’s claim that the motor started life as a 327 beneath the hood of a 1967 Camaro”. Not really.
3892657 block was used in the 67 model year for (A) Passenger car (Impala / Belair / Biscayne), Chevelle, Camaro, and Corvette 327’s through the mid to late part of the model year, (B) 350 Camaro all year, and (C) Z28 Camaro 302 all year.
Assuming the VO321KL listed for “Chassis #” in the auction is correct, then the KL code tells you the block originally came in a 67 Passenger car as a 327/275 in front of a Turbo-hydramatic 3-speed automatic transmission.

I agree with everything stated in the reply, This is a 1967 Block small journal 327 with a a crank , 6” rods and 302 standard bore forged pistons made to correct pin height. The PCV hole at the back of the block was not produced after 1967. This is not a DZ engine it just has similar internals to make a 302 ci SBC. I no longer have a project to put this engine in.Thanks for the input.
Tom G
Yes this was never presented as a DZ 1967 302ci Camero engine.
This is a 1967 4” bore block, small journal (pcv hole, draft tube at the back of the block) I don’t think they produced that after 1967? 283ci crank with the internals listed in the other post.
The aluminum 416 double hump heads are aftermarket and have the 2.02/1.60 valves.
The purpose was never to try and make something that wasn’t, it was just to get to a ci that GM produced and was a performance engine.
Thanks for your feedback, Tom G
One more clarification for anyone reading —
67 302’s were not coded DZ. That is the 1969 Z28 engine code. 67 302’s were coded MO (or MP if they had California smog). All 68 302’s were coded MO.
How to calculate CID.
CID = 0.7854 x Bore x Bore or squared x the stroke by the number of cylinders.
CID = 0.7854 x 16 (bore 4”x4”)=
12.566 x 3” ( stroke of 283 crank)=
37.698 x 8( no. of cylinders)=
301.584 C.I.D.
1968 302 was a 2 bolt main large journal and MO which I have . Also have spare large journal 302 crank, never know when you might need a spare lol.
