Whats the HP rating on our 7.5? I heard somewhere that it was 300?

[johnnshepherd]

i think it's something more like 250-275. the supercharged v6's HAVE to upgrade to the 8.8 or just sit around and wait till something breaks. I am staying normally aspirated, however. I kept the 8.8 and added a limited slip differential and 4.10 gears. No problems at all with my mods (cold air, full exhaust, tune, and long tube headers)

pat at steeda told me its good for atleast "300 rwhp."

This may be off topic but have searched and can,t find anything. Can anyone tell me for certain if my 08 7.5 has 31 or 28 splines?

It's a 28 spline.

7.5's have 28. If you notice all t-loks for 7.5" are 28.

But Lets Say You Go Buy An Eaton Detroit Locker Or True trac LSD And 410s For The 7.5 and they are rated for like 500hp wouldnt that make it just a simple axle swap to make it a compleatly stronger rear end for more hp?

Fixed ^
If you want a spare 7.5 to upgrade and see how strong it is let me know.
