Installed the camshaft today - burnished and brushed it with copious amounts of Moroso gray moly assy lube. Cam slipped right in - but the #3 cam journal seemed much tighter that #1 and #1. I hope it's OK. I can still turn the camshaft with relative ease.
I installed the Rollmaster chain too - seems s bit snug, but it went on without any persuasion by hammer. :P
Does this look like acceptable deflection? I measured it as 1/10" or 2-3mm.

Should be good Mark.

The snug fit on cam journal #3 concerns me. I eventually got it past the journal, but it took a bit of time and wiggling. Now I want to pull the cam and measure. Dammit.

Look on the inside of your timing cover... on the boss the cam sensor pokes though is a boss of aluminum of unknown use.
The rollmasters are known to hit that flap of metal. A die grinder with a reinforced cutoff wheel will make quicker work of removing it (but smaller chips). a normal doublecut carbide burr will knock it down as well.

if the cam turns freely, find something else to worry about

Good to know - I saw that mentioned somewhere - but didn't know that it affected the Rollmaster units.

ok - thanks, I needed that. :P
