I do an upgrade conversion using the X gears and install a steel tower in the case and use the XR ribbed top cap, that is a very good drive when it is done. The lower is still the small shaft B1, but that can be upgraded also. If the lower gears are worn that is a good time to go to the XR propshaft kit..
Hope this helps..
Pm me if you have any ??

Dick, My Bravo Gimbal conversion is coming along quite nicely. It will house the Max Worx SS gimbal ring and the Merc HP gimbal helmet. It will have the electric trim sender unit too. I will send along pics when finished. This gimbal unit and a "Mr.Gadgets" Bravo Drive would make a solid package.

Good chance your "blown 525" is a 525 SC which is a 454 with an POS Weiand 177 blower that claimed 525 HP but only made 490 HP but to answer your question, any 454 will fit. This is a general question and not a drive question.

I don’t think even the XR is rated for that much horsepower. I’m running 700 and blew up an XR drive. Twice. I’m running a Teague platinum which I believe is rated at 800 and I’ve had zero problems. I would call Teague performance and consider this drive and save yourself a lot of money in downtime
