66 SS Chevelle L-78 Idler Pulley etc

[Chevelle SS 396 L78]

It's tough these days finding vintage L78 engine parts. I know, as I've been collecting date correct parts for my 1967 L78 engine build for over 1.5 years. I would think it might be a bit easier for a '66 L78, but maybe not.

I still can't seem to find a decent 6223 crank. I gave up a long time ago finding a 2774 deep groove water pump pulley for my date correct short style water pump. I'm gonna try a stock pulley and hold my breath. I have the proper crank 3 deep groove pulley and a deep groove alternator pulley.

You might try OPI.com for the crank pulley....I bought my c.i. 3 deep groove pulley from them and the quality was fine.

Good luck with your search!
