The ZR1 is a totally different motor. So the answer to your question is no. The ZR1 is a 32 valve motor as opposed to the LT1's 16. And still today it is one bad *****.

I think your answer is no.
But all ZR-1's had LT-1 motors.
ZR-1 designated a:
Performance suspension package
M22 4-speed
and LT-1 engine.
Suffix codes for the LT-1 are:
1970 CTV
1971 CGY
1972 CKZ

In the C4 world the ZR1 was a performance package that included the LT5 engine (DOHC). But you could not buy a C4 with the LT5 engine without the ZR1 package.
