BUT.... less he builds them to you need to talk to Coan or someone like that. i have had them build custom stall at $1300.+ and they will know how much one of there stall is going to stall at in back of your engine with the rear gear you have. size of carb heads cam and weight if you think you need a stall

I am guessing that the next best performance improvement I can do is throw a cam in. or even a TC? I originally had a 2800, now a 1800, is this the right choice?

I originally purchased a ZZ4 350 and a SSF 700R4 and had the rear changed to 4.10 or .11 not sure, This went into a 1976 GMC 1/2 Ton Pick-Up Truck that weights 6200 lbs and has 16" wheels stock.

Other than taking out the Old Engine/Tranny and replacing with the New, what kind of set up should I be looking at for a Truck like this , Rear Gears?, Special Cooling? What size TC should be in the truck? What kind of Cam can I put into the ZZ4 Engine? Someone Suggested Voodoo Cams, any thoughts?

Wow, with that engine, the low first gear in the 700R4 with a 2800 stall and 4.10 gears it should snap your neck on take off and 1-2 shift should come pretty quick. I just read the previous posts so now I know more about your vehicle. 6200 lbs is a lot of beef to move even with the ZZ4, which is typically ideal for vehicles under 4000 pounds. With all that weight getting the tires to smoke may be a problem. A cam change to something set for more torque may help.
