How freely should a new cam sensor turn when not in the engine? Should it free spin easily or should it have a slight drag to it? I ask because my new one turns fine, but is much tighter than the old one and doesn't free spin.

should have a little drag.

Okay, that makes me feel better. I wrestled with it a little bit to get it to seat properly and couldn't remember if it was spinning like that when I started. I finally got it to drop down like it is supposed to. Thanks for all the help a few months ago with my new car. I have had the engine block and heads checked and freshened up at a local machine shop with new forged pistons (All of the old ones had wrist pin play). Then I had a local turbo buick guy assemble everything. He posted this thread on it:

I should be firing it up for the first time this weekend if all goes well.

What timing chain is that?

Some cam sensors can be a real whore to seat in...had my fair share. Make sure the engine is well primed before you twist the key...and follow proper cam break in procedures.
