This episode features the installation and first firing of the 482 cubic inch big block Olds that has been in the works for over a year and a half. You’ll first get a good description of the components on the build, which is basically a 455 block bored 0.125” over, partially filled with block filler & has a steel 4 bolt main conversion kit on mains 2-4, a 425 steel crank offset ground to 4.250” stroke with big block Chevy 2.200” rod journals, K1 BBC 7.100” long steel rods, custom Diamond pistons, CNC ported Speedmaster aluminum heads, and a hydraulic roller camshaft. You’ll see the engine run on a dynamometer, but unfortunately there was a problem with the dyno, and we were not able to do any full throttle pulls to measure torque or horsepower.
At 9:08, You’ll see me remove the old engine, modify the G-body alternator to power steering pump bracket to fit the 455 block, and the G-body AC bracket, then install the new engine. The oil system has an external oil cooler with a remote oil filter mount + oil thermostat from Improved Racing Products, and is plumbed with -12AN lines. I modified one tube on the American Racking 2” primary to 3-1/2” collector stainless steel headers to clear the top oil fitting going into the block.
Lastly, you’ll see us start the engine in the car, and that’s where it goes south.
If you want to see more details on the engine build:

Smitty @ M&J ProFormance for building what so far seems to be an awesome long block enigne (he will get me my real intake manifold that’s been milled for flatness soon).
