So I opted with tko 600 and I have a 9 inch rear end. Any pointers on how to strengthen it to hold that much hp? Or is it good as? Sorry for the newb questions, but I just wanna do this right. Again, thanks for the help. You guys kick a$$

Dude. That is impressive.
Just make sure your clutch kit and drive shaft is rated for the power and you'll be good to go. A couple things to think about.
- OD ratio on the 600. They offer two. If you plan on highway cruising go with the lower .64. But if your just romping around town or closed track racing the .82 has a great close ratio feel.
- Plan out your rear end gear ratio for your rear tire size rolling diameter to help pick the trans ratio. Online gear calculators like this MOTOR - A Rear Axle Calculator are super handy.
- The 600 has two spedo drive possibilities depending on what kind of gauges you plan to use. Mechanical and electric. Make sure they send you a hole plug for whatever sensor one you don't use. If you go electric spedo drive ask them to include the sensor and a pig tail plug to wire in.
- If you go with the mid shift option keep in mind it defeats the neutral safety switch capability. If that's important to you a switch could be installed on the pedal box.
- The new bell housing should be indexed to the block.
