total of 193 vehicles equipped with the 195/283 engine-- block codes were MD/manual trans--MJ pg trans some were coupes and some were convertibles--no smog equipment on them ---they also "supposedly " had a California emissions 195/283 engine ,block code is MP same as the 302 Z28 engine because Chevy used the same 283 block for the 302 engines

Very interesting I wonder how many are still around.

NO !! The 302 was a 327 block with a 283 crank.

Lew Silverman · 09-23-2011, 09:36 AM

Back then a 4-inch bore in a 283 was a "301". Very popular when those blocks were plentiful!

Wasn't the 302 in the Z/28 a 4 bolt main block?

On the 1967 Z-28 302 engine.

The block casting #3892657 used for 1967, was a 327 small journal block.
2.299" mains / 2.000 rod journals
And with 2-Bolt Main Caps.

A special forged steel crankshaft (casting #3815882) was 'tufftrided'.

I've heard of the 283 67' Camaro,,,,,never realized it was an
'export only car',,,with a 4-speed.

But after some research,,,,,found out they were assembled in Switzerland.

I'd never heard of the car, either. You learn something every day.

This trumps my previous weirdest Camaro - the new 67 SS350 I saw sitting on a dealers lot with a bench seat and a 4 speed. It had some ungodly gears in it, I'm thinking either 4.56 or 4.88. It was that dark turquoise green with redline tires, painted wheels, and bottle caps.

It sat there for quite a while and then disappeared. I never saw it again, not even at the tracks in the area.

I don't think the 396 had been released yet, so this would have been the ultimate Camaro at the time.

The '67 302 engine used the formentioned 657 block, "green" rods from the solid lifter 'Vette engines (which were the small journal version of the famous "pink" rods), a special crankshaft that was nitrite treated, the 30-30 solid lifter Corvette camshaft, foged pistons that had a dome similar to the original dome on the high-cormpression 327s, 2.02-1.60 valve 462 casting number heads, the unique intake manifold, 780 cfm Holley (actually the design carb was a 585 cfm carb, but it never made production), and the Corvette flat windage tray. The intake and carb made the package the killer.

The strangest engine that never made production was a 3-2bbl 350 with the Corvette 350 hp hydraulic cam and big valve heads. If you ever see a copy of an original assembly manual, there are several pages devoted to the installation details of that engine, including a drawing of the engine that used a triangular air cleaner similar to the one on the 3-2bbl Corvettes. Chevrolet had intended a small block package that would have mimicked the big block engines released in the Corvette that year. Production costs and less than acceptable performance in the warranty tests (remember that was the first year for the 5-year, 50,000 mile warranty) caused them to nix it. They were also aware that Ford was stuffing a big-block into the Mustang, Pontiac had planned from the beginning to put a 400 in the Firebird and Chrysler was releasing the 383 in the Barracuda and Dart. They needed a big-block offering so the 396 got the nod over a high-perf small block on the street.

All that info was related to me by a GM engineering manager who worked on the Camaro project. I was introduced to him when I was building my Z28 stocker in 1979.

look in a late 60s or early 70s Motors manual and you'll find specs for a 67 Camaro 350 horse 327. I guess the story was that Chevy was considering the 327/350 before the 350/295 was done.

I think in 67 and 68 the 302 had 2 bolt main caps...the 4 bolt main blocks showed up in 'DZ' 302 engines in 1969, if memory serves correct.

I thought all 302 were two bolt mains

Dirk Olson · 09-25-2011, 01:27 PM

I am not sure but were not all narrow journal small blocks 2 bolt and the wide journal 4 bolt blocks came a long in 68?
