Thread: 302 sbc, Cimmaron?

Tweet

My older brother had a Camero SS when I got back from the service in '70. It had a 4-speed and a really hot motor. He said that he had to order the motor separate from the car, because Chevrolet wasn't allowed to put that particular motor in the car at the factory, BUT that the dealership could pull the factory-installed motor and drop this motor in if he ordered it. He did. He said that it was a special 302 CI called a "Cimarron". There was no question that it was "hot" for its time.

Can anybody verify this? I've talked to a lot of Chevy guys and only have had one even seem to know what I was talking about.

I can tell you that Chevy never used the 302 after 1969 as far as I know but I have been wrong before.
The only Cimarron I have heard of was a Caddy from the 80's.

The only 302s that Chevy had that I know of are the DZ engines . This was a 4" bore 3" stroke (1967 S/J and 68/69 L/J )11.0.1 C/R Forged pistons and crank short block . 2.02 in/1.60ex valves double-hump heads .And this engine had a special 455 / 481 Lift solid-lifter #140 cam . They also had a 780 CFM Holley with a factory aluminum high-rise .This engine was rated at 290 HP . But I do think it was makeing more then that . There was a cross-ram intake . And it was a service part installed option #3940077 . This cross-ram intake ran two Holley 600CFM carbs . These engines and early Z-28s were made for Trans am road racing . But they also did run strong on the street and strip . I personally did see what they really could do . They were fast right out the box .

Thanks Denny . Here are some more photos of the early S/J DZ 302s .

Check out this Drag car ! 1968 Z-28 DZ 302 . They called it the "Sea-Terror" . It was ordered new just for racing . And has remained a race car it's entire Life . Last known to have only 255 miles on it . It was a NHRA and IHRA E Stock national record holder . COOL

Hay even Denny W like's them and he's a Ford guy . COOL

Heres a photo of the headers that were a production option . They came with the RPO Z283 package . And they were shipped in the truck with instructions of the new Z-28 . The headers had 1.75" primary tubes with 3.5" collectors .

I can't remember the correct name, but I know what your talking about, I have 2 Ebay ad's somewhere on 2 of them, they both were over $100,000.00!!! each last yr. Yes they are 302's, I will look for the ad's

In early '68 I was nosing around the Cone Bros. Chevrolet dealership in Anaheim, Ca. and came across a '67 Z. From a distance it looked like a plain jane Camaro, no stripes or badging on the fenders. There was a small Z28 emblem just left of the drivers side headlight. I know there was badging on the back, but I didn't look. If memory serves me right the price was somewhere close to 3 grand. I wish I'd pursued the car further, but at the time I was really jazzed on a '68 Charger.

well, i remember those ebay add's they were for the expierimental HEMI 302's from smokey yunick they came out in 69 and were put in very few 69's not very many of the motors were built and they guy wants like 90k 100k

Thanks, guys.

Could be the same ones, I can't find the ads, I would have to pull out some disc's to look for it, and they could be packed in the garage, then I'll never find them.
