I have a 95 F350 PS/DRW/LB which I bought in 05' with 102,000mi from original owner as of 6/29/12 it has 920,798 mi. on the original engine. It runs great and pulls even better. It pulls commercially anything and everything that pays me money Ha,Ha .Upgrades done are an all steel cowl induction hood to help get the heat out of the engine bay,Banks inter-cooler hardware kit using a cooler from a 99 PS,TRUCOOL tranny cooler,Magtech alum.finned tranny and rear diff.covers,DP tunes 40T,60T,60E.S&W gauges BTS/Trans,Temp/EGT,K&N cold air intake,BD 4"exhaust,HPturbochargers did my upgrades on turbo with banks impeller(a little diff. pitch and height than the stock garrett splitter wheel) and 1.0 exh. for faster spool-up WOW! I'm hoping to hit 1 million miles or more before having to put my drop-in crate engine in.I can only hope that it will be just as good. Hopefully! I can be of assistance to any one needing help with their PS with problems that I may or may not have encountered. GOOD LUCK!
