This seems to be a proven combo for making 400+ to wheels all day long, im leaning on buying the setup for a stock rebuilt bottom end 347 2001 motor very soon but want to check if theres any hidden PITA;s involved such as PTV clearnaces any fly cutting required?? and what kind of gas are people running.. MPG with a 6 speed?? any info would be a great help

 

If you get the setup from Texas Speed and you tell them you'll be running the MS3 with those heads, you won't run into any PTV issues. They build the heads just for the MS3(sink the valves if I'm not mistaken). I ran regular ol 93 in my car. I would see any where from 15-19 in the city and about 28 on the highway with the stock 3.42s
