brian Posted February 5, 2008 Report Share Posted February 5, 2008 This is a 66mm bore 4mil topend with approximately 20 hours on it total. I bought it used from a guy who had run it all of 4 hours. I installed it and ran it for about 15 hours more. There is a small amount of corrosion in the cylinder wall at the top of one side (seems like about .002/.003 deep). I was skeptical of this topend because of that at first, but it did not pose a problem as the topend tested at 152 lbs (evenly-both sides) after its first weekend trip to the dunes and it ran very strong, and as you can see from the pics, I had it set up very rich. I was misled by the seller when I bought this topend so I bought another topend from Bansh-eman around the same time. It is more agressively ported and is stock bore so I am going to use it instead of this one. It is ported for 4mil crank and runs strong. Included in the package are pistons, rings, wrist pins, wrist pin bearings, and 20cc domes. (wrist pins and bearings were new when I installed them) The pistons are 66mm Weisco pistons for Blaster. The domes are relieved for Blaster piston/4mil combo. No cylinder base spacer needed. I paid $375 for this topend. I will ship to lower 48 for $275.......my loss is your gain !
