Rob,

Absolutely true... Chevrolet sold thousands of the service LS-7 engines (which by the way were quite a bit different than the intended production LS-7 scheduled for the 1970 Corvette).

The service (parts counter) LS-7 454 cid engine was sold as a long block and had a cast iron block, cast iron open chamber heads, forged steel crankshaft and connecting rods, a high rise aluminum manifold, the .560/.600 lift camshaft from the ZL-1/second design L-88, and a (depending upon the source of information) 12.00 or 12.25 to 1 compression ratio... Basically all the best parts.

It really is a shame Chevrolet stopped selling it... Great engine!
