Yes it is a civilian block, I pulled it from a 1959 schools bus that had been turned into a schoolie. I will throw up some pics soon and as I go as I know I will only create more questions as I go.
Yes Jerry this is the first gmc engine I have been in, I have only rebuilt a sbc before and really only been around more modern engines and drivertrains. I just had a passion for the history this engine has so im embarking on this and it will go into a 1954 gmc. So it doesn't need the full flow mod that is talked about a lot? I will see once I open it. Then I can just swap the canister oil filter for a modern spin on and it should be good? That would be a lot easier as I could just follow the plumping it has now. I knew the numbers were off for the Clifford's stuff but chalked that up to advertising, but is the quality not great? I'll see if I can track down some Fenton and nicson stuff. I don't know if it needs to be bored but I always plan for the worst and if I don't need to even better. I do think I will shave the head a little to get the compression up.
I'm not sure if it does need a full rebuild but parts are rusted out and pitted plus
It leaked oil from everywhere and I just want to fully rebuild it before I set it into the truck, piece of mind I guess 😅
