That is not whats necessary for 650hp and an #8300 truck IMO. I fried this trans from March until now...about 30,000 miles/2 yrs total on the trans. The first 20k was no problem, I had no icp and a laggy turbo setup. Ever since March, the last 10k miles has wiped it out. Surprised it lasted this long. For clutches, you need Elite's stage 4 raybestos clutch kit at the very LEAST if you are doing it yourself. The suncoast kit barely scratches the surface of extra clutch material. Waste of money and time if you're going big.
Direct pack has almost nothing left.. I am losing power from it. 1&2 hit like they should. Trans has the Suncoast Red Eagle clutch kit (IP3), billet input and low reverse. Trans didn't hold close to 650hp (maybe more) successfully... and that is $4k in parts including solenoids. The converter is an 1800 stall built by Circle D in Houston; it's my favorite part about the trans.
