I'm going to attempt to bolt the trans with the 340 engine today. I have 2 pressure plates that came with my project and not sure which I should use.

Pressure Plate #1) Is a rebuilt unit (I think raybestos) with 3 fingers and is fairly heavy.

Pressure Plate #2) Is an older brand that is supposed to be performance. It is a Ztreeter brand and has lots of cone shaped fins as opposed to the 3 fingers. It is lighter.

Which should I go with?
