1971 ZR2 hood and other differences?

[Bruce N.]

I know there were only 12 or so of the ZR2 produced but I would like to know if there were any differences between the regular LS6 and the ZR2 besides brakes and suspension? I have heard they may have had a different hood and/or engine components. Thanks.

No hood or engine differences

-------I seem to remember that ZR2s had an L88 style radiator set-up which would necessitate a completely different radiator support. The hood is not changed from stock LS6 or LS5 for that matter. Engine would be unchanged from LS6, already a very formidable combination.........Bill S

Bruce,

ZR2 racing package consisted of F41, J50/J56, V01 mandatory options, also precluded options A31, N40, C50, C60, U69/U79 & P02.

LS6 could have been ordered with all or none above.

Thank you for your responses. Warren can you help me out with a translation for those option numbers - or help me find a site that translates them. Thanks again.

F-41 is the HD suspension option. It consists of larger front stabilizer bar, higher rate front coil springs and a 7 leaf rear spring.

J-56 is the HD brake option. It consists of "dual pin" front calipers, front caliper supports, caliper pistons with Pyroceram insulators on the face, and HD brake linings for all 4 calipers.

V-01 is heavy duty cooling. It consists of the installation of the GM #3007436 aluminum radiator (and supporting pieces like radiator support, hoses, etc.). No radiator shroud was used with the 3007436 aluminum radiator.
