i'm heading for that motor build and just wanted to know if any thing could be done to a 5.8 to get better mpg?
You know that's true !Have the stock intake extrude honed.
Me neither, but I've ported many a cylinder headExtrude honing is something I've never had done personally, but I have an interesting book on it. Shows impressive gains on the stock intake. Specially for a stock or just warmed over motor.
A bit of ignition and exhaust worklots of things to think about, is it worth the extra cost over just getting a stock re-manufactured block? what kind of milage are we talking about? just did a guesstimated mpg on my last road trip and got around 13-15 mpg highway with 185+ miles on it and some kind of timing issue that i'm working out.
