We spent a couple of days at JMS Racing Engines, in El Monte, California, talking with owner Mike Johnson and his machinists and builders to get the scoop on what makes a successful budget performance-engine build. We’re assuming that you’re starting with an engine that is in good condition and hasn’t had more than one overbore, you plan to reuse as many of the stock components as you can, upgrading to higher-performance pieces as your budget permits, and you do the disassembly and reassembly yourself. As with any complicated process like this there are plenty of myths to bust, and just as many procedures to follow. We’ll break everything down into bite-sized pieces.

Devise a Plan
We cannot stress this enough—the most important part of any engine build begins with a good plan. By good we mean one that is realistic and fits within your budget. Ask yourself: What do you have to work with, and how much can you afford to spend? Are you starting with a lightly used original bore stock block that just needs new rings, bearings, and a hone, or are you starting with a “mystery motor” of unknown origin? We’ve all heard those stories of free engines that were guaranteed to run but, upon closer inspection, needed a lot of work.

A RADICAL SHIFT
When you're a teenager and the police know you by name, it's not usually because of your volunteer work or class-topping GPA. Not at all. That was especially true for Jeff Kainz when he was behind the wheel of his 1975 Camaro. In the '80s, while cruising his hometown in North Dakota, his buddies with police scanners often heard the police tell one another: \"Kainz is out on Main Street.\"
