2000 Chevy Blazer 4.3 Vortec
Part # C-3090 Yeah I know it says it won't fit. Go ahead and buy that cheap bike chain that came stock. And better buy the tensioner so you wont hear it flapping around. This was on the mid 90's 4.3 with the balance shaft just like my 2000. Don't believe me do some research. Look up a 96 crankshaft and 2000 crankshaft. Same P/N. Do the same with the camshaft, same P/N. 96 had a balance shaft also. This is a better built chain and sprockets. That bike chain major thumbs down.
Bottom Line Yes, I would recommend to a friend
