While my motors are torn down, I am re-bearing the bottom ends. However, I am a bit torn on which setup to go with. I am set on the clevite 77 series but not sure on the following...
H - High-Performance
HD - High-Performance bearing with dowel hole
HK - High-Performance bearing with moly/graphite coating
P - Standard Clevite 77 tri-metal bearing
V - High-Performance with Lead Indium overlay (On Main Sets this indicates partial groove also)
VG - High-Performance with Lead Indium full angular grooved bearing
Anyone care to chime in on the setup? I am thinking either the H or P setup but leaning more towards the H.

In most builds I use the H series. However, in the larger engines (over 1000hp) I use the coated (HK). Now you will probably only get the HN or HNK bearings. The N means they are narrowed instead of having a chamfer.
If you use the HNK bearings, play close attention to clearance. The bearings are a little larger than the uncoated ones, so the clearances will probably be a little tight.
