I just traded a 1971 Monte Carlo with a chev 400 sb for a 1977 Camaro type LT with what we were told had a 350. We were looking at it and it didn't look like the right color for an engine. It doesnt even have any rust on it at all. my uncle said it was a high nickel block engine. most people have never heard of it, and i didn't until that day. I want to know more about it. i have the casting numbers but i would have to look at it again. i just want to know more about it, how much horse power it has and such. i will put the numbers on here soon. thanks!
