I would have put this in the Windsor Power if I were you. Anyway, theres a chance that the 7.5 will hold up forever or might break leaving the line at the strip. I would upgrade it to a 8.8 in fear that I would snap an axel.

The 7.5's are stronger than most think, and should handle 275 horsepower as long as you don't bolt on a pair of real sticky tires or slicks. Although I swaped in an 8.8 about a year ago, I put a set of 3.45 gears in my 7.5 and ran it for years. It's still in one piece out in the garage. You can also bolt a girdle on to the 7.5 and strengthen it's weakest part...the bearing caps.

Try to find a truck 8.8....
The towing package could be 3.55, 3.73, or 4.10
get the right axle and gear for cheap
