Yup like he said there, with a 4k governor spring you;ll need to upgrade the valve springs to 60lb HD springs. or you'll be tempting a valve to float and kiss a piston.
The old 12 Valve is getting a little tune up...
I just dropped my truck off this afternoon to get a much needed tune up. It's a 98 CTD 12 valve Quad cab 5 speed with 105K miles. I needed to have the KDP done as well as a new serp. belt and a new fuel solenoid boot installed. I recently replaced the fuel filter, rubber fuel lines, lift pump and a bunch of other crap.
Now I'm having a 4K spring kit installed, the fuel plate will get a little grinding, I'm having a 4" Magnaflow exhaust installed with no cat and a straight through muffler, having the timing set as well as adjusting the valves and the injector pump timing. He'll also turn up the injector pump and see how much power I can get out of it before I start eating up the stock clutch. I'm looking for a balance between decent power and reasonable EGT numbers, I know I can take it higher but I don't want to be past 1050 - 1100 when towing if at all possible.
Can't wait to get it back and feel the difference, she's been feeling very sluggish lately.
