Description
Both front and rear bumpers are aftermarket fiberglass replacements from Ecklers, and the rear one is the one-piece style, as I did not like the crease in the middle of the factory 74 bumper. Included with the car is an aftermarket Hot Rod Air A/C system which I took off when I added the billet serpentine front accessory drive a few years ago. It saved weight and the engine runs cooler without the big condenser in front of the radiator.
It has a hydroboost conversion, which is a total game-changer. Very powerful and responsive brakes. The calipers were replaced with remanufactured units by Vette Brakes five years ago.
I don’t know much history on the car prior to 2010 when I purchased it...
I had the repaint done in 2012 and the quality of the paint is excellent. It gets many compliments.
In 2013, I had the engine run on an engine dyno at Dynotech in Memphis. At that time, the engine made 566 HP at 5500 rpm and 590 pound-feet at 4300 rpm. I have the dyno sheet. However, the engine was still a 460 at that time (454 bored .030 over) and it had an approximately 11.5 to 1 compression ratio.
In 2018, the engine was rebuilt and half the dome was milled off the pistons to lower the compression to around 10 to 1 and make it more pump gas friendly.
At the same time, a Scat 4.25″ stroker crank was installed along with some porting of the heads and intake manifold and new valve springs. The cam (CompCams custom hydraulic roller, 230/236 at .050, .604 lift both sides, 112 LSA) and everything else stayed the same. This new build was not run on the dyno but the car feels even stronger now, especially in the mid-range.
