Quality control is not there.

After years of making a flexplate, one would think that they could get the mounting holes indexed correctly. One out of three holes would line up. The other two had to be enlarged. Not happy at all with this.

I'm currently doing an engine swap in my 94 gmc k1500 from a 350tbi to lq9 6.0l and this flexplate fit perfectly!! not to mention its very heavy duty with the extra power I'm putting into it.

I purchased this when doing a convertet swap. The hughes is a decent piece for the money. If my stock plate held fine at 540whp im sure this will have no problem at 650whp with my new setup. I trust it will work fine.
