For decades, Ford fans have dealt with a well-known weakness of the factory small-block Ford block. it has a nasty habit of splitting right down the middle when horsepower levels get serious. At the 2025 SEMA Show, Summit Racing unveiled a definitive solution with its new Street, Performance, Competition iron small-block Ford block, engineered specifically to handle the power that exceeds the capabilities of stock castings.
This new 8.2-deck Windsor block isn’t just a copy of the original; it’s a fortress. Summit started with superior Class 35 German iron, cast and machined in the U.S. Crucially, they added significant amounts of extra metal in key areas to completely negate the splitting issue that has plagued Ford builders for generations. The result is a block that is noticeably heavier than stock, and that extra mass means the SPC Ford block is ready for boost, nitrous, and high-rpm abuse.
Beyond sheer strength, the block features modern upgrades like a priority-main oiling system, which ensures critical bearing lubrication even under extreme duress. Like the rest of the SPC lineup, it ships with upgraded main cap hardware and is bored 0.005-inch under, allowing your machinist to hone it perfectly for your chosen pistons.
According to Summit Racing’s Justin Weideman, there’s no pre-set horsepower limit on these blocks. They were designed specifically to take the abuse that destroys a factory block. For Ford diehards looking to build a serious small-block without fear of catastrophic failure, this is the bulletproof foundation you’ve been seeking.
