Nicknamed "mouse motor" for its compact dimensions compared to other V8 engines of the time, production began in 1955 with the 265 in³ (4.3 L) engine used to bring performance credentials to the Corvette. The displacement changed over the years, eventually reaching 400 in³ (6.6 L), but none caught on like the 350 in³ (5.7 L) small-block. This engine is still in production today at General Motors Toluca Mexico plant (primarily for the GM over-the-counter Goodwrench powerplants), but is no longer offered in current model year vehicles since the year 2004. Its production numbers were impressive, with more than 90,000,000 built.

302cid

Chevrolet produced a special 302 in³ (4.9 L) engine for Trans Am racing from 1967-1969. It was the product of placing the 3-inch stroke crankshaft from a 283 into a 4-inch bore 327 block. This engine was only used in the first-generation Camaro Z28. Conservatively rated at 290 hp (216 kW), actual output was around 360 hp. This block is one of 3 displacements that underwent a transformation for the 1968/1969 period when the main bearing size was increased from 2.30 in to 2.45 in

If I were you, I'd go and build a 302 up, they are great motors and extremely rev happy (due to the short stroke), will still put out more than enough power to satisfy your needs.

Cheers,Chris

NB: Those power figures are from Stock Motors, so with a little or alot of work those figures can go upwards rather quickly.

why bother with a 302 chev when you can get a 400cuber its excatly the same weight and dimensions its alot easier to get 400hp from 400cubes than 302 and alot cheaper and more reliable. dont get me wrong the 302chev was an awesome motor its just than you get alot more bang for buck with more cubes. the other prob is that the 302 was based on a 327 block good luck finding a 327 thats not worn out beyond tolerances. remember the first gen camaros are 40yrs old now. though in saying that all 350s are 4in bore if you could find the right crank and rods it could still be done
