Camaro Fuel Injected 454 Engine Camshaft

The Motown block locates the camshaft is the Chevy engine's original position, so all aftermarket and OE timing sets will bolt up. Also, the cam bores are original size. The camshaft was degreed 112 degrees.

"Of course, functionality was the priority when we designed the block," says World Products' Bill Mitchell. "But when you look at those ribs and the aluminum finish, you couldn't help but say, 'wow, that looks cool!'"

Like the iron Motown blocks, the aluminum version has a 9.025-inch deck height, four-bolt mains and it accepts all OE-type accessories. World has a unique way of inserting the steel cylinder liners, too, which prevents oil from being drawn between them and the aluminum bores.

"That oil acts as an insulator and prevents the aluminum from transferring heat from the steel liners," says Mitchell. "It's an issue with all aluminum blocks, but we've solved it."

The Motown Lite block has maximum bore of 4.125 inches, allowing for a maximum engine displacement of 427 ci. Mitchell says a fully dressed engine, complete with aluminum heads, intake and carburetor, weighs less than 450 pounds.

Lifter bores in the Motown block are indexed and have stock-spec .8437-inch bores. Solid lifters from Comp Cams were dropped in place to complement our solid camshaft.

Here's our 454's bottom end all buttoned up. Because the Motown block is externally identical to standard small-block Chevy blocks, all OE-spec accessories bolt up to it, such as the timing cover and snazzy Milodon oil pan. A Manley double-row "True Roller" timing system is behind the cover. Next month, we'll finish the assembly, bolt on the injection system and head for the dyno to see what this huge small-block is worth.

With a light grey texture that tells you right away it ain't iron, World Products' new Motown Lite aluminum small-block casting weighs just 100 pounds-almost half of a comparable Motown iron "race" block. It's made from 357-T6 aluminum and like its iron cousin the Motown Lite has a Chevy-original 9.025-inch deck height. Four-bolt mains are standard.

Pricing, however, may be the block's best feature. It lists for $3,495 with billet steel main caps and $3,295 with nodular iron caps. Order it as an upgrade to a World Products Motown crate engine, however, and it'll add just $2,000 to the bottom line-a bargain, if you ask us.

So, who's up for building a small-block ZL-1?

Very visible in this photo are the exaggerated cylinder bulges, which house enlarged coolant passages. The front-to-back ribs also aid cooling and help tie the block together for additional strength. Freeze plugs are billet aluminum and screw in to place.

Special O-rings at the bottom of the cylinders help secure the steel cylinder liners, preventing oil from squeezing between the liners and block-a condition that reduces the aluminum's ability to transfer heat away from the liners and could eventually dislodge the liners. Liners are available in 4.000-inch or 4.125-inch bores. With a 4.000-inch crank, that yields a maximum of 427 ci.

Compared to a standard small-block Chevy-or even World's own Motown iron block, for that matter-the aluminum block's cross-valley ribs are a new sight for enthusiasts. Besides reinforcing the block, they are drilled to cross-feed the lifter galleys with oil. The block also was designed to accept dry sump oiling systems at either the front or rear.
