So, after all of that, what are the best bearings for me to use?

Here is what I have: Ford R302 block, Eagle internal balance forged crank, Eagle H-beam rods, neutral balanced Romac dampner (stainless), Racemaster billet steel double roller timing kit and zero balanced KEP flywheel (this is in a GT40 with Porsche G50/50 transaxle.) To suite the G50/50 gearing and achieve a top speed of 200mph (6842 rpm in 5th) , the solid roller Comp cam & Crower HPPO lifters, AFR 205 heads, Jesel SS shaft rockers, Comp 929 springs(titanium retainers) and valves(2.080/1.600) were speced to have a sweet spot of 2500-6800 rpm and the engine will seldom see more than 7000rpm and never exceed 7200rpm. These rpms will be only occasionally seen as this is a street/occasional track days car. (BTW, displacement 337ci with 4.060 bore and 3.25 stroke and Jack Roush 3 piece EFI intake w/ 36# inj.)

So as you can see I have an engine that will be used somewhat mildly interspersed with moments of sheer terror. I haven't torn down the engine to be able to make the decisions talked about in the Clevite article; I didn't get at all having to tear down the engine to see what kind of wear patterns you have in order to decide what kind of bearings to use. I want to put in the right ones in the first place and then "run it like I stole it" without having to worry if I am going to spin a bearing or worse.

It sounds like that with my eagle crank I ought to be using Clevite 77 which is what I had listed since everyone else I saw was listing them :-) I am thoroughly confused on the H or P ? And what about Calico coating them?

Thank,
Lynn
