I am currently building a 5.3 for my 68 c10. Stock bottom end with rod bolts. Prc stage 2.5 heads. Texas speed 224r cam ls6 intake. Plan on 80 lb injectors on E85. Wanting to make 700-800 rwhp. Thinking about th bw s475 but I'm not turbo savy. Do I need t4 or t6 and what ar. Also th400 3500 stall 373 gear. Thanks for the help.

t4 1.10 a/r with an 87mm turbine would be ideal for your goal. You could get it done with a cast 75 or go with a nice billet 76 or 80 to keep the boost low.
