Life happened real hard a couple years back and I sold my cherished Mach 1. I have hopped into a trucking career and now have my finances in check where I can get another one. I am chasing a couple different options in the 03 year Azure Blue in color. We are buying it cash and have ability to put $15k in upgrades. Going all into the motor this time. Being newer to mustangs and power plants here’s the question. To build this 4 valve properly with trans and rear end to safely rock out 700+ rejoice how much will I be investing? Can my $15k cover it or will I be over $20k? Please keep the comments real. The flames can come out hard around here. I’m located near Milwaukee. What are the shops in the Midwest? Is Mike Post still around in Illinois? Think Marv at C&M is all gone in Wisconsin.
