Hi so I just bought a 1986 c10 with a 305 in it. It is far from a performance machine right now but I plan on putting a modest street engine (preferable 350hp or more) in it but I am a fresh college student with not a huge amount of money. Does anyone have any advice on what engine, I was thinking about a 350, and should I start with a short block and build up or just buy an already built engine? All input appreciated. Thank you!
