This includes a hardened direct shaft and the Transgo shift kit that will give you shift points around 5800-6000 rpm and all you have to do is just leave it in Drive and floor it. This combo will handle 500hp easily with a lockup converter and about 600hp non-lockup with a 1-pc hardened input shaft (+$300 Lentech 1-pc. shaft).

Of course, in addition to the above would be your choice of torque converter. A good converter will run you from about $450 to $700, depending on who you get one through. The most efficient stall converters that I have ever had experience with are Cameron's at Torque Converter Services in Columbia, SC. Don't forget to budget in a transmission cooler to go with that stall converter($50-$100). A good cooler is a must have with high performance and stall converters.

Now if you want to convert up to the AODE 2" overdrive band with the indestructable 2nd gear sprag, that will add $300 more in parts.

Now for those of you looking to breach the 600hp mark, you will need the Lentech 1-pc input shaft($300) and the Lentech strip terminator valve body($660). This combo will hold up to 800-1000 hp.

If you have any more power than this, you really don't have a streetable enough ride to even justify the cost or need of an overdrive transmission. Time for a built glide or a Lenco at that point.

lentech would be the route i would have to go- i dont see much point in having a toy with less than 700+ HP.
Thanks for all the info.
