Carroll Shelby Engines releases new small-block wonder.
02-18-09: Carroll Shelby's engine company has introduced a new aluminum Ford 351 Windsor engine block for builders. Lightweight being the key word, then new block can be bored and stroked to 427 cubes. Righteous. You can buy the bare block to build your next dream motor or you can have Shelby build one for you complete.
Much lighter than the Ford cast iron 351W, Shelby says their block was designed to be the strongest on the market. Each is CNC machined from A356 T6 alloy at Shelby's own engineering machining facility. The new block features a 9.5" deck height and bore sizes from 4.024" to 4.125" and 2.750" steel billet main caps that can accept crankshafts up to a 4.250" stroke. It also includes four bolt mains on No. 2, No. 3 and No. 4.
"This new aluminum block is an engine builder's dream," added Don McCain, Vice President of the Carroll Shelby Engine Company. "It uses stock cam bearings but can be bored out for roller cam bearings. With its stock oil filter location, expanded water jackets and four bolt mains, our block is a perfect platform for today's high performance engines."
The aluminum Shelby 351 Windsor uses standard FMC accessories with the oil filter in its stock location. It can be bored and stroked to be a true big block sized 427 for use in a small block package. Shelby also offers matching aluminum heads that are CNC ported. Optional black powder coated aluminum Carroll Shelby signature valve covers and air cleaners are also available too.
"Many Cobra and Mustang drivers in the 1960s wanted an aluminum small block for their cars, but the technology was too expensive," stated McCain. "From the Mustang to the Bronco, Cougar, F150 and Fairlane, this Shelby block is appropriate for any application that will accept a 351W. It's ideal for the Cobra and GT40 continuation cars, Sprint Cars, dragsters and high performance boats."
