The Athena Big Bore Cylinders
from Bigborethumpers.com are an all new casting specifically
for big bores. They are not simply bored out stock size blocks.
Athena makes these blocks with larger water jackets and thicker
cylinder walls to help with cooling.
Bores have special galvanic coated bores for long life.
Forged pistons have molybdenum skirt coatings.
Block, piston, rings, wrist pin, and special big bore top end
gaskets are included.
Step by step instructions included (most models)
These kits are bolt ons with no machining required.
Special introductory
prices - for a limited time only.
