I put in my cam tonight, and timing chain. It seems like the comp magnum double roller timing chain is going to be rubbing against the block above and right of the cam. (looking at the block from the front.)

-is there a clearance that I should be expecting? stick a .050" feeler gauge in there?
-is it normal to have to grind off a bit here? I wasn't expecting this, perhaps my cam is too far in....?

 

It's pretty normal, just take a die grinder and knock down the high spots. There's not much growth or wear in that direction at all, so as long as there's "enough" clearance it should be good.

It's hard to see through the paint, but you can see where this block is clearanced for the timing set.

 

aces, thanks. I can't tell much from that pic though...

I guess i'll remove the cam sprocket, and cover the cam, and hope I don't slip and nick the end of the cam, or get shavings there.
I guess i'll try a die grinder and stone, and remove ~1/8" and retry.

 

A carbide burr will be a lot nicer to use than a stone.

 

My cloyes dbl. roller is rubbing there at the 3 oil holes. is it ok to grind there?

 

Yup

 

thanx,

 

Seems to be pretty common on newer blocks... they must be leaving more metal around there than they used to. Didn't ever used to be a problem. Now it happens all the time.
