TTI 1 7/8"primary headers,not desided on exhaust size yet but dual 3or 3½" will be installed.
prosystems E85 dominator
lysholm twinscrew supercharger
904transmission with a nice and tight 3500rpm+stall converter
how fast? dont know will hopefully be able to find out this summer low 11.s high10.s would be nice
power: dont know but i gues the stockblock will grenade long before i reach 20 pounds of boost so 600+hp at the crank and 550+ftlbs seems like a fair target.
