Hey whats up people? In 2007, I purchased a 1946 Pontiac Streamliner and after 7 yrs of collecting enough money I finally threw my Pontiac into the shop. I have the original straight 8 engine and I am really thinking of restoring the engine, but my question is: what are the advantages and disadvantages of keeping the original engine? And would I have to keep the original transmission? Would I have to purchase a transmission within 40s-50s or can get a modern one?
