I'm currently deployed and trying to put the parts together to build up my Dad 71 Mach 1. It is bone stock and been inside since 81. 351c-4v was blown in 79. Missing the 4 speed. Want to build a clean street/track car. We have a new 351w that was built for dirt track b-mods a few years back. It should be around 350-380hp. This is a list of what I'm looking to do: -Lower a few inches -Run at least 10" wide tread in the rear. -Run a floater housing. -Update suspension & breaks. -Run a newer mustang transmission. What I'm hoping that you all could help me with is part details. Whats the best suspension companies that I should look at? What would be the best width of housing to get wheel clearance? If I run a modern manual what bellhousing do I need? Any other detail or area I am bound to miss. I'm not worried about cosmetics or interior, only chassis and drive-train. Any and all advice welcome. Thank you.
