1970 LT-1 Thermostat Housing

[George C.]

Did the 1970 LT-1 have bolts in both sides of the t-stat aluminum housing or was a stud with nut used on one side?

A stud with a nut was not used on ANY Corvette application I know of for thermostat housing retention. What was used was a "double-ended" stud with a hex for the shorter position. The stud was once available from GM under GM #3776391 but it's discontinued. I expect that reproductions are readily available. The lower portion of this stud often suffers from corrosion damage and needs to be replaced.

Approx page 155 of the new manual, as well.

George,
With as desirable car as you have, I'd encourage you to spend the money on the new manual. That purchase can ultimately save you many dollars in mistakes.

There is a picture in the new 1970-1972 manual, for those who are visually inclined. A lot of the studs I see on restored Corvettes (all 1968-1972 small blocks had that stud) do not have the proper configuration. I don't know where they are sourced from, but there are a bunch of "close but no cigar" studs out there.

Is this a Cuban or a knock off?
