My first mods what do you think??
Just about ready to crank the 305 over in my s10 for the first time completly hooked up! And i have a set of swap headers and a Holley AFPR coming on order from Jegs. Oh ya went ahead and built the exhaust with 3inch head pipe and a Flowmaster dual 2.5 out muffler with pipes exiting out the back Z/28 style. What do you think i should set the preasure to on the afpr when i get it? I read the the tech articles on this site but they are for a 350 not 305.

The pressures can pretty much be set the same. Start with 42-45psi and take it from there. On a stock 305 that should be plenty.
