Remember we still align the marks together and then you will notice a different position of the crank from straight up. That's why there are three marks for a three keyed crank gear.

Yep, you're right, my bad

It's cool Richard.....just say that you didn't have your glasses on!

I didn't have my glasses on.

On a 400M the retard is in the timing chain set. just get a good aftermarket set and set it up and you will be good to go. the 400 gets a bad rep due to it being a smog motor but with todays cams and better intakes these engines respond alot better than some think
