RevTech 97” & 106” Big Bore Kits with ENGINE, INTAKE & EXHAUST

There’s no replacement for displacement! These big bore
cylinders with forged and coated KB pistons increase the 658652
displacement of an 88” Twin Cam to 97” and raise a 96” Twin
Cam to a whopping 106” with no case machining. Each piston
and cylinder are measured out, then sized to matched and
finished honed ready to be installed. Both kits give you a 10:1
compression ratio. Available in black and natural finishes.
Each kit includes:
RevTech 3.928” Cylinders with machined fin edges in black
wrinkle or natural finish. KB forged pistons with anti-friction
skirt coating and moly rings. Multi-layer steel head gaskets.
For best performance results add cams and Carb/EFI upgrade.
