Update: I have tracked down a 336 GMC that’s runs good with everything needed to swap over and tranny for $2000. Turns out my 270 block might not be Savable but I also tracked down another 270 block pistons and crank for 1000$ I can’t make a decision keeping the 270 would make the truck original but loose some driveability while putting the 336 with and being able to swap in a nv4500 later easier, would give me a lot more driveability while still being “correct” for a 59 GMC. What do you guys think between the two? I believe in the long run the 336 would be easier to find parts for as it’s a debored 389 Pontiac. I plan on driving the truck 2-3 times a week in the summer and the occasional road drip for fun thats a day adventure at about 60 MPH.
