Timing will be more stable with one installed so inturn that should account for a better running engine and a little more power.

I installed one on my high mileage 340 and it help the timing stability a lot!

Every one said Don't bother! there two weak and won't help!

I have a new one and planned on installing it on my new 408. New chain and new tentioner didn't mix for me,(to tight) so i will have to wait until this one is high mileage :D

I could have got it on with a pry bar......but it will go back into the closet.
