"POWER NATION" slant six build

Did anyone catch the follow up episode? Lol,that pathetic build made nearly 140 h.p.. They did lots of extra work to the Duster,brakes,rebuilt 904,rebuit the front suspension and rear,better gear ration in the diff. But holy hell,that first episode,the pistons in the slant were WAAAAY down the hole. CR must be barely 8:1...
