Upcoming mod questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I finished my build last summer and would like to make some mods this coming winter. Truck is basically a weekend cruiser. I would like to add a cam, stall, intake (TBSS).

Info on the truck.

Truck is a 70 gmc swb 2wd. It has a 6.0 Lq4 with a 4L80E. 3.73 posi 28.5 tall tire.

I have the 1-7/8 tube DT headers, thru a full 3 inch exhaust.

Current Fuel system is a Stock tank, walbro 255 on the frame rail, using a vette regulator.

Questions

I have a TBSS I picked up on LStech last year. It is complete. It has the injectors, etc.

Can I use the TBSS injectors? Or should I use the Stock Lq4 injectors?

I beleive I will have to run a adapter to run the TBSS throttle body?

Cam and stall suggestions for this setup anyone?
