I need to know what the proper / best X-Dim is for a 28 magic

The power plant will be a Raylar 650 ,Blown.... Was thinking of just a normal bravo XR, Any suggestions?

Have no idea what the stock X-Dim should be, or what it should be based on my application.

THANK YOU

Since you're now going for 800hp, drive can go down but engine won't go up. Maybe seek to talk to the magic guys... Even though they're gone.. I bet they are still around Havasu somewhere and would be good for questions.

XR will be fine. Trick is the number. Good luck! It should be a handful of fun!
