Those were late 70 ' s - early 80's parts designed for NASCAR use.They even had the Pontiac logo cast into them.Harder to find,and even hotter were the ones that were of the Buick version.GM went with the corporate small blocks around 75.
Very cool! I'd rock them but to many W motors in the fire then this stupid 454 jet boat motor needs built now. Got it up on the engine stand to tare down. Should be off to machine shop in soon.

I have 2 but they are both being used. To many coals in the engine rebuild fire. LOL! Besides I'll be zipping the bolts off this so no worries about being sturdy enough to pull the crank and pistons. Need to get this one pulled apart and off to the shop asap. I have a 1959 Triumph TR3 motor to rebuild this winter too. Wife deserves to have her baby on the road come spring due to all of my automotive/boat shenanigans.
I pulled the last one (short block only) out with my own two hands. 1500 out of a 77' triumph. This one will be smaller than that so probably 140lbs. I'm to old for that now but I will admit that carrying a couple 30lbs kids everywhere has really made my arms stronger. These small 4 cylinders were designed with motorcycles and racing road coarse in mind. They are pretty light until you get into the 6 cylinders where they didn't seem to care about anything.
