Comp Block, last one left

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 😉

-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
