How can you visually tell if you have a 400 flexplate? I have a 335 stroker and it vibrates like a bitch.. I just replaced the balancer thinking and I got it out of balance when I installed it, but it still vibrates.. the only other thing I can think of would be the wrong flexplate...

 

A 400 flexplate will have a weight welded to it, it's roughly 3/4" to 1" wide and 5 1/2" to 6" long, it curves to the shape of the flex plate.

 

Which side is it on? Side the faces tward the front of the car or rear?

Thanks

 

I don't remember and it's too late to go out and check. It's easy to find because it's right on the outside edge. I think it's on the front side, yea because it makes getting to the one torque converter bolt difficult. It must be on the side towards the engine.

 

yes it on the side facing the motor and i hate it because that bolt is a bitch to get tighten

 

Hmmm.. I don't remember having any trouble putting it on.. I'll look tonight but I bet that is my problem...

 

its not hard to start and snug down its the tighting part that sucks becuase of the weight i cant get a good grip on the bolt so i dont round it off. damm they should have thought about that when they made them
