its a sweet virgin bore "511" 4 bolt main 400 i picked up...and a vintage Martin Turbo systems draw trhough carb turbocharger setup (vintage rayjay aircraft turbo) that i demoded off a 79 corvette...fits under the stock hood, not many kits were made for the vette/Fbodies...far more kits still remain of the truck/RV kit thats much taller and wont fit the cars.
i have a th400 and dana 20 tcase from a 72 commando and 75 cj5 narrow track axles (D44/D30 6 bolt hubs, 3.73) that i was gonna build into a hillbilly 4wd jeep/indycar...change the angle of the 4 corner quarter elliptical springs and toss on 33" tires and take it offroading after a day of racing...
