Hey guys,

Well, I had to get a new engine block cause the other one was cracked. Started reassembling the parts, I got to the cam, and when I put the timing gear on the cam without the chain, and the cam is pushed in all the way, it doesn't line up with the bottom sprocket. it's about an 1/8" closer to the block then the bottom gear. Is there supposed to be a spacer or a bearing/bushing in between the block and the top cam gear? Or is it suppose to be that way? It wasn't that way on the other block. Thanks

Do you have the bottom gear on backwards?

It shouldn't have a bearing unless it's a roller cam, and there are no other spacers that I'm aware of...

I have ran a Bearing behind the Cam Gear before and it was about a 1/8" Thick.But it sounds like you removed the Parts from another engine,there was not a Bearing there?When I ran the Bearing I also ran a Cam Button.

no there wasn't a bearing on the other block. This new block is a targetmaster "M" block. Please tell me that, that's not the problem. Because if it is I will be one pi**ed off "M"other f***er.

The cam "floats" in the cam bores. The cam lobes have tapers so the lifters spin. These are angled in opposing directions so the cam isn't forced in or out.
The chain is sufficient to keep it aligned with the sprocket.

Too bad about your cracked block. I'm feeling that pain myself.
