Thread: Does a flex plate makes a difference

Tweet

I have a 434 smallblock, thinking about goin to an aluminum flexplate. I have a b&m plate now. Does the weight between the 2 makes a difference?

Anytime you reduce the rotating weight of a component, it will help in some way, but I would think the difference between an aluminum plate and a steel plate would not be worth it unless you were chasing a record and needed another 1/thousandth of a second E.T. improvement. If you're bracket racing, forget it. Other's opinions may vary.

It was 1 lbs between the 2. Im just tryin to get sum rpm. I dont know where to find it at. 1/8 mile only goin thru traps at about 6700rpm. 434cid
