The parts are from manufacturers of proven quality, but replacements can be sourced from alternate vendors if the need ever arises. This mitigates the risk of total reliance on a single vendor with their own exotic engine design and sole-source, proprietary parts. Proven conventional architecture also beats exotic in cost, size, weight and complexity. If conventional works just as well, why would you want to pay…

These engines are a proven, straightforward way to drop in big power. Borowski Race Engines (BRE) and Dart Machinery's history with BBC race engines goes back to about Day 1 of our common history in the late 60's. We are pleased to offer a range of 555 cubic short blocks using Dart Big M and Sportsman blocks to cover a wide range of applications.

The RHS version includes the required custom timing cover. It is the foundation of our 800 horsepower, naturally-aspirated, pump gas build. This beast can drive to the track and tear it up when it gets there without breaking a sweat as you'll see in this ad's video. The foundation can be an RHS or optional Dart aluminum block. An aluminum block transfers heat better…

The Callies Compstar center counterweighted crank with stock stroke brings a lot to the party. Having 8 instead of 6 counterweights increases stiffness by 25%. Harmonics are reduced because each cylinder has its own two counterweights. These two factors combine to minimize crank flexing thereby protecting the block, bearings and rods from excessive wear and fatigue. We have seen that using 8 counterweight cranks…
