How bout an intake





any able to tell me about this water inlet spacer between the intake and Thermostat housing??

[Fast67VelleN2O]

The spacer was used on ZL1 and other high horse (L88) applications in order to clear the temperature sending unit with the curved neck.

It was also used on 1965 396 425 hp corvettes .

Not on any factory-built ZL-1 Camaro. They used the standard t-stat housing with no spacer just like an L72 or L78.

[Enoch]

The spacer was used on 396 65 vettes as Chuck said and then on 67-69 L-88 vettes.

So ZL-1's had a 660 housing?

[William]

All '69 bb Camaros located the temp sending unit in the LH cylinder head and used the '660 housing. There are vintage engine bay photos of the #3 & #5 ZL1 Camaros that show this.

Corvettes may be different.

William,

Any chance you could post those period photos of the two
ZL-1's you mentioned?

I could scan them and send to someone for posting. Everytime I have tried it here the pix are too big.
