Yes, I know I'm asking for trouble when I ask for "opinions" but I'm willing to accept that.

I was offered a 1958 GMC 336 that runs great but was pulled to make room for a new bellybutton. I wasn't looking for a V8 for my '53 GMC but because this was offered I've been considering the swap. I know the 336 is a de-bored Pontiac 370 but other than that I don't know squat.

What do you think? Is it an engine worth messing with? I hate to ask this question but what is one worth in good running condition?
