Maybe we should’ve called it “stroker science.”

There is, after all, a formula involved in creating a stroker engine. Things like bore size, overbore, crankshaft stroke, and connecting rod length must all work together to produce the coveted added displacement without nightmarish clearance problems. Some stroker combinations can be done with factory parts; others may require custom cranks and even custom engine blocks.

It can very get complex, very fast.

There are stroker rotating assemblies that will help take some of the guesswork out of stroking an engine, but many people still assemble stroker engines on a part-by-part basis. In conjunction with the Summit Racing tech department, we’ve put together this list of popular stroker combinations to help you understand the basic math behind each combo.

For this installment, we’ll focus on some common Chevy strokers. This is by no means a complete list, but it does contain some of the most common setups.
