This is a 1993 Corvette ZR1 which was bought in Virginia in december 2004. The engine had been prepared in '94 by Lingenfelter and was updated later on in the UK by Geoff Jeal in 2006.

The engine has been fully prepared by Geoff Jeal (famous Lotus engineer who worked by the time on the ZR-1 project) to have a bigger displacement (368 ci which is about 6 liter).

The engine compartment simply looks gorgeous.

The modifications are the following:
