If the head work is anything like mine, then 20psi on a T34 (what exhaust housing?) could be around 250bhp.

I'd get some steel rods mate, and I wouldn't use Vulcan again if they were the last engine builders on Earth. I would rather build my own intergallactic ship and search other solar systems looking for some half monkey, half slug type aliens that would do a better job than those bunch of CU_NTS!!!


Oh, and good luck with the build by the way
