VERY nice Bob! I was admiring it in your icon. lol
The one of mine I mentioned is a 73 Trans Am, 462ci, Bill Miller aluminum rods, forged dished pistons and ported/polished Edelbrock heads. Air is squeezed by a Garrett 4788 turbo and passes through a CSU built blow through carb and augmented with progressive methanol/water injection under boost. She's intercooled too.
In a previous life it had a smaller turbo, more restrictive exhaust and stock heads with a mild port. At that time it made 1068 hp and 998 ft lbs torque at 5500 and 5200 rpm respectively (crank) at 15 psi. Our current estimates with the new heads flowing almost 30% more now at all lift and the bigger more efficient turbo are in the 1200 hp range at around 5500 rpm. Conservatively. Engine/timing cover/pan/etc is painted House of Kolors Galaxy Grey base/clear coat after smoothing the block. Heads and intake were polished by hand from 60 grit down.
But its not built to go in a straight line only. Front end weight has been reduced a number of ways, including the one piece tilt front end, suspension, engine and body changes that also lowered overall weight a bit. She's now around 3600 pounds (still a porker. lol), but weight distribution went from 60/40 front to rear to 54/46. She sports 18" wheels with 295/30/18 rubber all the way around and a corvette style front suspension with a single monoleaf composite leafspring and A-arms made by Vette Brake Products.
The idea is to be able to stick with a modern vette around corners and blow it away on the straights. I'm hoping to do some Pike's Peak tye racing with it at some point.
Oh, and Vintage Air A/C. She's not quite back on the road yet so the main pic is a little old and the wheels, paint etc have changed, but this will give you an idea. Her webpage is also at 1973 Pontiac Trans Am 455, Garrett 77mm turbo & Methanol injected - American Torque .com
but I haven't updated it in a while.
My other car is a 67 Grand Prix convertible. Only year they made a convertible, and about 5600 built. Mine is one of 205 with a manual trans. They are in the floor console with a Hurst shifter. Most people checked the little box though and got the optional 4 spd. Mine is the only one I've seen so far that had the base 3 spd, also in the floor console. Although I have heard reports of 2-3 others. Interesting note: Pontiac didn't have their own 3 spd capable of handling their V-8s. So all through the 60's into the 70's they contracted with Ford. Its a Ford toploader.
The main pic below is a couple of years old so doesn't show the new wheels, tires, tilt front end, etc. The car will be painted soon. Turbo is not installed in that pic either. I also have fuel injection on the shelf for it, but too much going on right now to install.
