Ultima 124 ci Competition Series Twin Cam Replacement Engines 

Just like Ultima's EVO style engines, this 124 ci Twin Cam style replacement engine "features high quality components at an affordable price. The cases utilize Timken sprocket shaft bearings. The crankshaft assembly is the same Ultima has been building for years, dynamically balanced and featuring forged H-beam rods and forged aluminum pistons from Mahle.

"The heads feature conical valve springs, chromoly retainers, manganese bronze guides, compression releases and stainless steel valves. Valvetrain components include an Andrews 67H set of cams, and Ultima's 4140 steel adjustable pushrods topped off with 4140 forged steel roller rockers. 

"The cam chest components include a billet oil pump and billet cam support plate with late model hydraulic chain tensioners. Choices of finish include black, polished or silver. With plenty of power, these engines make a great replacement for a tired stock motor or a custom build."

The 2032 cc/124" displacement is achieved with a 4.125" bore and 4.625" stroke. The compression ratio is 10.0:1. Features include a compression release valve, 2.10" intake and 1.70" exhaust valves, 252/260 duration, 0.570 lift camshafts, AISI 4140 adjustable pushrods, forged dome piston, forged 3-piece flywheel, rocker boxes with a '93 and later EVO style breather, a billet oil pump and cam support plate and late model hydraulic chain tensioners.

Ultima also offers Shovelhead style 96 ci engines with 3-piece crank and pavement-eating 140 ci 'El Bruto' Competition Series Evolution style engines.
