@Mike B as usual you are correct, the LS5 had 365 hp and the LS6 had 425 hp in 1971. According to the Corvette Black Book the ZR2 option used the LS6 engine. Only 12 were made with this option in 1971.

Didn't the LS5 had 365 gross hp on the '71 Corvette? I thought that only the LS6 had 425hp (and that the ZR-2 came with the LS6)

I can't make any different between this and 454 LS5 model. It has same performance (Sae Net and Sae Gross). The body look same. All i know it's just car suspension (this one got rallye suspension) and this Vette can run faster than standart LS5 model
