[QUOTE="Kevins89notch, post: 10434189, member: 31255"] 550rwhp is more closer to the number I've sene fail before, and even then, its the high RPMs that kill it. Try bolting on H/C/I and getting just shy of 26mpg on the interstate. I know my 5.0 with a vortech could. :) Maintenance, what maintenance? I drove my 89 from IL to FL, and used it as my sole, 100% true daily driver for about 15 months or so. I had 4 or so oil changes done at a shop, and that was it. I never even popped the hood myself in that time period. How about the head gaskets not sealing properly? Maybe the intake gasket leaks. Were the rockers adjusted properly? Were the pushrods the proper length? How is the idle? Just saying. Huh? Either setup needs to be tuned for max HP. However it is easier to backyard tune a blower setup. I can adjust the fuel pressure, lock the timing, and put down 340rwhp is a S-Trim on a 5.0 anyday. With a H/C/I you wouldn't see 300rwhp. I think I've covered that pretty well. [/QUOTE]
