I originally purchased this car back in 1992 outside Philadelphia, PA. for the paltry sum of $3000.00. That is where the car sat, in storage, until I was able to have it shipped out here to sunny Tucson, Arizona. It is a numbers matching SJ with the original XF code 428/370 horse motor. It retains the original 3.23 safe-t-track rear, and the M-40 auto transmission. It has 65,000 original miles and has had no body work that I can detect. I am only the third owner and have all the documentation for the car including the protect-o-plate.

Once I got the car out here and started to drive it, the usual issues reared their ugly heads. The front crankshaft seal started to leak as well as the rear main seal. I decided to sell my sportbike and fix my GP up right. My good friend and expert mechanic was kind enough to help me with the project. The motor was pulled and disassembled. The heads are casting #46. These are not original to the car, but are dated January 7, 1969. I determined that the original heads, 62 or 16, had been replaced probably under warranty when the car was fairly new.

The heads were treated to a 3 angle valve job, new springs, new valve guides, and hardened valve seats. The original cam which was well worn out, was replaced with a Summit 2802, 224/234. The following parts were also replaced: rocker arms, pushrods, lifters, oil pump, fuel pump, water pump, timing chain upgraded to double roller, fan clutch, radiator, distributor, belts, hoses, plugs, wires, all gaskets and seals, main bearings. The original Rochester Q-jet is still intact, also treated to a rebuild. The original pistons and rings as well as the crank were all in fine shape and were left intact.

Helping it all breathe are a set of Hedman Headers running into a 2.5 inch exhaust system with 40 series Flowmasters. It now rides on BF Goodrich Radial T/A's on the orignal Rally II wheels. The car runs great now and I love how it all came out. I don't really see that many Grand Prix's around and I like having a car other than the most popular ones. I plan on enjoying it for many years to come.
