1970 GTO Convertible

Palladium Silver with Black Top and Black Interior

This is a private party sale, I've owned the car since 1987. The car is fully sorted, it runs and drives like new.

Documentation includes: original window sticker, original build sheet, dealership owners manual folder, Pontiac Historical Services (PHS) documentation, vehicle registration cards from all 3 previous owners, many service receipts going back to 1970.

Meticulous body-off restoration performed between 1994 and 1997. Body and paint was done by Gary Wirth when working at the Highland Auto-Body restoration shop in St. Paul, MN. Gary also assisted in most aspects of the restoration. When completed the car won it's class at the 1997 Land of Lakes Muscle Car Classic in Plymouth, MN.

The car has been carefully resto-modded with the following changes from stock:

The orginal numbers matching WT 400ci block has been stroked to 461ci.
Machine work, balancing and short block assembly was done by Jax Specialty Engines in Hamel MN, Bill Meyer also assisted with the build.
4.25" Forged Eagle crank with forged Eagle H-Beam rods.
