Not sure what they have been selling for, but there is another one for sale in VT on Cars.com owned by Nick Cage ?? for 30k. But I like the white one better !! As I'm sure you know the value has dropped sharply. I feel due to the lack of parts or qualified techs to repair them. I have seen some clean low mile stock ZR1 go for 18-20K
Alot of bang for the buck.

I don't know the specifics of the Supernatural 475 other than to tell you that the "475" refers to its power output.

In general, to make 475 hp from the LT5 required a "top end" job which was usually head porting, injector housing porting and sometimes partial porting of the intake plenum. Additionally, some vendors installed throttle bodies with larger main bores.

The cams were usually retimed. Sometimes so-called "RB" cams were fitted.

An lower-restriction, aftermarket exhaust was installed.

And, of course, the ECM calibration was canged.

Done right, this took an LT5 to about 475 SAE net.
