The all-new SCAT small-block Chevrolet forging makes use of a big-block Chevrolet-diameter snout for improved twist resistance.

Responding to a need in the marketplace, SCAT Crankshafts has two new crankshaft forgings that are developed and ready to go for the 2015 racing season.

The first, a 4340 steel 3.750-inch stroker crankshaft developed for the Ford Modular engine, takes the diminutive 4.6L powerplant into the 4.9L range, according to SCAT’s Alex Gonzalez. Previously, customers have had few choices to build more cubic inches into the Modular engine. The eight-bolt crankshaft flange allows for the use of widely-available Cobra flexplates and flywheels.

“This crankshaft uses center counterweights and is brand-new for this year. It uses a factory-style tail and nose and increases the cubic inches to allow the large Modular market to take advantage of the engine’s breathing capability. There’s an eighth-inch radius on all journals. It also uses Chevrolet rod journals to allow for the use of a 5.850-inch Chevrolet connecting rod,” says Gonzalez.

Also new in the company’s lineup for the show is their forged 4340 small-block Chevrolet crankshaft that uses a big-block-Chevrolet diameter snout that’s meant for use in centrifugal and roots-style blown applications.

“With a normal small-block Chevrolet crankshaft, when you put a blower on, it can rip the snout right off the crankshaft. The bigger, beefier snout helps to prevent that from occurring. This crankshaft used to be available only as a billet piece, but now we have it as a forging which allows for a significant cost savings to the customer,” Gonzalez explains. The crankshaft comes in with an MSRP in the $1,900 range.
