I believe that the original 1976 Camaro was equipped with a 327 cubic inch
2 main bearing engine. When you ordered the copo option #Z-28, you got the
high performance Chev truck 327 with a 283 forged crankshaft, a special
Duntov cam and liters that were mechanical. .030/.030 lash. Also included
an aluminum high rise intake, headers, different sized alternator pulley,
corvette brake parts, heavy duty u joints, The engine block, borrowed from
the truck division was a special 4 bolt main bearing piece. This
combination with a stock bore was listed as a 302 cubic inch. I became
familiar with that combo because that was what we did with our C gasser.
Engine would rev until something broke. Advertised horsepower was 295 at
3200 rpm. If you turned it to 7500 which it would easily do, it made in
excess of 500 hp. in good race tune. A real factory hot rod for sure. In 68
they refined it with light weight hood and grill and bumpers, and if you
had the right connections at the factory, you could get the "special"
editions that the sports car guys ordered with the quick steering, huge
brakes, etc. They had special options for the drag racers too. All gone by
1969, when the big block cars emerged. Great drag cars, but they would not
stop or turn like the small block cars. This was the year that Mary asked
the question, "Do you want to keep racing, or do you want to be married?"
We stayed married for 50 years. I made the right choice. Both of my
brothers are at Pomona at the Winternationals. They went over to the dark
side and race special mustang cobra factory racers. Man those things are
fast and quick. 156 mph in 8.53 sec. Faster than we went with our C Gasser
for sure. Long time ago. Still miss it and her too.
