"The Tonawanda engine plant kept VERY accurate records on engines built during each model year. These "Summeries of Engines Built" list EVERY engine we built by assembly number and description. This number crossed over to a suffix code so from them I could determine how many of each SUFFIX CODE we built. Sometimes, as in the case of the L-89 engines built, I had further records. In these cases it was "engine canceled, not replaced" and then a date.

In the case of the L-89 engines in 1970, in October 1969 the L-89 396 option was canceled, not replaced. As far as the LS6/L89 NONE WERE BUILT. Period. In model year 1970 NO aluminum head LS6 engines were built. In 1971 there were 200 LS6 engines built and put into Corvettes, ALL were aluminum head (due to the lowered compression ratio).

I've spent many years researching big block production (ALL big blocks). I'm always open to new information, DOCUMENTED AND IRRIFUTABLE. But if anyone wants to contradict me they'd better have better records than I do!.

Sorry if this sounds "hard", but it's late and I'm tired. If you need anything more feel free to Email me.

Just quoting what I was told by Fran. As many know, he was a plant manager for many years at the Tonawanda plant and had aquired all the records for a period of time including the late 60's and early 70's. To my knowledge his widow now maintains these records. R.I.P. Fran

Thanks Rick. Fran's say about big-block production is pretty much the last word.
