Hi Guys, I'm back from spending the last few weeks reading Don, Don Jnr and Dans build thread on their T's and RPU. So I slowly catching up with the many awesome projects happening. Dave first... Are you a plumber???? your headers are a work of art. What size primaries are you using going into 3.5 collectors and what sort of HP do you want out of that small block??? Maybe you should put a huffer with twin 4's on top of it...Heck you are doing a nice job of that exhaust.
