Hi camwinder here. In the Jan. 1975 issue of Rod Action Magazine,Brian Brennan had an article with stats and tech. infomation about the Chev. four cyl. engine and I'm hoping someone out there might have that information. I have one of those engines, a 63 that was built up for an A-altered, but it's in need of refurbishing, so I need Brians or anyone else's information. Any help would be very appreciated. I was told that this engine is 12 to 1 and I know when I first got this engine and would rev it up, it was up and down very fast. Thanks ahead of time, camwinder.
