Fuel pump will be fine...might consider going to 5.3 injectors though. Better check you crank runout too...you going to put a lot more power to a motor with 57k on an already suspect bottom end. I have an 08 cvo road king and stayed at 110 but did heads and s and s 570 cams over last winter. Had about 43k on the bike at the time and .003 runout with great oil analysis results. About 7k into this riding season and I hit the rev limiter once by accident passing a few cars and the crank shifted and I found bad rod bearings on tear down. Cured with a darkhorse man o war crank. Don't let my story discourage you...build your motor and if the crank takes a crap on you then fix it. With bad bearings I was on borrowed time anyway, but now when I need to I can build a big power motor and not have to worry about my bottom end again. Good luck with the build

[QUOwTE=eriksweden;18662303]About bigger injectors , is there any good way toraise fuel pressure instead ?[/QUOTE]
im no expert and maybe kirby or someone can explain it better. Even if you had 100 psi from the fuel pump the injector still dictates how much fuel can be put into the motor over a given period of time...controled by the tune. If I'm wrong, feel free to correct me. As far as going 124, I took it thst the op was going with the 117 drop on from HD and hadn't planned on splitting the cases...yet lol.

Now Im installing s&s cam plate and oil pump, S&S tensioners and install the lower cam sprocket and inner cam bearings. Anything else I should look at while in cam chest? Is 594 to much of a cam for this build or is the 585 the way to go?
