Merlin Lite - Aluminum BB Chevy
Superior Strength 357-T7 Aluminum

The major benefit of the Merlin Lite Block is, of course, it's light weight. It weighs about 125 lbs. less than a comparable cast iron block.

The Merlin Lite Block is cast out of dense, durable aluminum alloy that is both rugged and easy to repair. It includes special design features such as diagonal bracing in the valley and head bolt/stud bosses, reinforced lifter bores and solid bulkheads.
