Thanks for the reply. You are the first to definitively say 440/TTI/Borgeson will fit including all the research I have done here so far. All I had read here was power steering was a no go with a 440 but never mentioned the Borgeson box. I am assuming the TTI full length headers and not the shorties correct? Are they 1 3/4 or 1 7/8?? Did you need to install a cooler for the Borgeson? Thanks I am feeling a bit of hope of not having to go with a 360 stroker with a manual tranny as I already have a 440.
