Re: 1966 79 water pump.

Two different water pumps were used. One with a bypass and one without a bypass.

L-79 engines were installed in 66-67 Chevelles and Chevy II and had aluminum manifolds and external bypass.

After 1967 L-79's, including Corvette, lost their aluminum manifolds and external bypass.

Most 1963 and later Chevrolet engines with aluminum manifolds utilized external bypass. The exception was 1970-72 LT-1. All big blocks utilized external bypass regardless of manifold type.

Joe no 66 Chevelle was built with a L79. And only a handful of 67 Chevy II where built with a L79. The production numbers for both 67 Chevelle L79 and 66 Chevy II L79 is a small number

According to information I have, the L-79 was available in 1966 Chevelles beginning in the spring of 1966. I do not have any build numbers, though. As a matter of fact, the L-79 was also available for 1965 Chevelles and rated at 350 HP. I had a friend that purchased one brand-new. 6,021 1965 Chevelles were equipped with the L-79. For 1967, 4,048 Chevelles were equipped with the L-79 which was rated at 325 HP.

I do not have any information regarding L-79 build numbers for Chevy II's.

Re: 1966 79 water pump.

Yes those numbers are correct for Chevelle, for 65 and 67. But zero was built for 66. For Chevy II in 66

5,481 and 67 the number is approximately 6

built.

I would not say that the number of 65-67 Chevelles and Chevy II with L-79 was small. There were almost as many of these cars built as there were L-79 Corvettes in the 1965-67 period-----15,556 Chevelle/Chevy II versus 18,682 Corvettes.
