Description
Want to make big power without the expense of buying longer rods, or a deck-plate block? This is the answer!
This block features a
-1″ thicker deck-
-OEM 6.7 deck height
-1″ thicker cylinder base
– the cylinder wall is 2″ shorter due to the extra material at top and bottom of the cylinder
-Much Thicker main webbing
– improved 300 MPA high tensile alloy
-High tensile alloys should be honed with diamond hone.
-Cam oiling from mains has been shrunk from 7mm to 5mm for improved bottom end strength
-Do not tap main holes deeper, this is the source of the failure for most of the block failures we see
-Due to the many requests we have for different bore sizes we left the bore as cast so it can be anything you want, from approximately 4.0″ to 4.250″
-The thinner the wall, the less cylinder pressure you can run without failure đŸ˜‰
-These blocks need to be bored and honed to final size.
-be sure to bore .450″ lower than the bottom of the cylinder for piston skirt clearance.
-the crankshaft may need to be clearanced
-Our race crank usually drops in without additional machining
