I went from powerdyne to an SQ trim. Glad I did, traded some bottom end but gained upper rpm power. This may be in part to the SQ with stock pully will deliever atleast 11 if not 12 pounds on your setup. the bottom main support bracket is the same as the powerdyne and you can leave it if you have modded the bottom like I did to mount the atl in the smog pump location. the top plates are different and will bolt right up the the main support with no mods. The belt tensioners are very different and may require you to change to alt/waterpump etc belt out of the way depending on your current routing.
If you have any questions or need pics shoot me an email, be glad to help you out.
