4g64 vs 6bolt 4g63 stroked

[Goat Blower]

I guess I'd say I'd build the later 7-bolt with the split thrust bearing, the earlier 95-96 one is the one people seem to have problems with. The Evo motor I built was a 2.4, but had the three piece thrust, which was easy to build and get aligned properly. I know Shindley had some problems with the early 7-bolts and had to order specific bearings for each main following the amount of dimples specified by the factory pounded into the block. He had it figured out, but I never dealt with that as I was always building 6-bolts.
