Cam shaft help!!!!

[SLDPULR]

Dear friends and fellow truck nuts. I am in need of some help. I built a motor for my 1969 C10 that was going to be a pro street build. About half way through the build someone made me a offer to buy the truck that I could not refuse. I ended up buying a beautiful 1980 square body and I would like to put the motor I originally built for the pro street truck in the new 1980 but I need to tone down the cam.

The cam that is currently in the motor is a comp cams XE294H. It needs a 3300+ stall converter and in my opinion is to much for a truck that I would like to drive on a regular basis.

The 1980 has a Turbo 350C (electric lock up) in it and I bought a 2500 stall hughes converter. I will list out all my motor info and if you guys could help point me in the right direction I would greatly appreciate it.

I would like the truck to have the most power possible but still be streetable. This is a toy so I do not really care about fuel mileage. I would like a decent amount of lope if possible. Thanks guys and MERRY CHRISTMAS!
