Custom Chrome has released two new RevTech brand Big Bore kits with forged and coated KB pistons - 97 and 106 inchers - for Twin Cam 96" from '07-'14 and Twin Cam 88" from '99-'06.
Working on the basis that there's "no replacement for displacement", these Big Bore cylinders increase the displacement of an 88" Twin Cam to 97" and raise a 96" Twin Cam to 106" with no case machining.
Each piston and cylinder are measured out, then sized to match and finished honed, ready to be installed. Both kits give 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 and multi-layer steel head gaskets.
Custom Chrome says that for best performance results new cams and a carb/EFI upgrade can be added; a choice of replacement ring sets and head gasket is available.
