Ford 460 V8 in Pace Arrow vs. Ford V10
Having owned both, I believe the 460 will out pull the V-10 hands down. My '99 was supposedly 275 HP and was a disaster waiting to happen. Frequently, I had it in low gear and it was slowing down pulling a suzuki toad. On several occassions, my wife wanted to stop and let her drive the toad. IF you are in to headers, they will help, any header. I would not necessarily spring for the most expensive, (bank$) There are many headers on the market and most will give equal bang for alot less bucks...As Gary B mentioned, quite a few folks spring for a single flowmaster muffler and larger exhaust pipe. OR, if your rig happens to have a catalytic convertor, Just replace the muffler with a test pipe and go for a test drive. You might find that just that little mod is enough...BTW: we only kept the V-10 for 7 months and 17,000 miles... Good luck with whatever you choose...
