Weddle Performance Engines Inc.

I went to this shop for years as mullvain's, and Jeff has continued the tradition of top notch work. Jeff and team have done all the machine work for my lsx, and though prices have increased over the years the price is still reasonable for the time it takes to do machine work/balancing/etc. As with any custom work sometimes things take longer, but still very happy with the value and quality for my build.

This is Archie and they did a great job on dyno tuning my 421sbc. They did a great job and got it set on kill mode. They also installed the motor for me in my 85 Monte Carlo with no leaks and no problems. I highly recommend them if you want your motor tuned to its max performance and capabilities. Thanks

The owner seems like a well-meaning guy who is working out the kinks of running a business profitably. Their work is good, the shop is clean, but the final cost came out to be almost 3 Times what we talked about (with no unforseen issues) and I'm extremely disappointed about that. Background: Jeff bought the small business about 18 months ago, changing the name from Mullvain to Weddle Performance. Mullvain, whose first name I forget, still works there but was looking to phase out and retire so the reigns went to Jeff. This place has been around a while, despite the handoff, and seemed to carry a lot of expertise. My Experience: I had them clean, inspect (disassemble and reassemble), and resurface my 32v Ford C-Heads. They also put in 2 spark plugs inserts. Initially the verbal estimate, which we went through carefully when I dropped the heads off, was $400-$450, plus an additional $450 if inspection revealed that they needed a valve job, which they didn't. I assumed it the total would be a bit more with shop fees, maybe $500, but that was acceptable. That's the going rate for head work in Illinois at the moment. After some slight delays that weren't much in their control, my fina

Mike Mullvain and his crew did a great job with the rebuild of my 360 Mopar motor. I had them machine, reassemble, break in and dyno the engine. World class work all the way. Friendly, knowledgeable and helpful in designing my rebuild. The engine performed better than I expected. Ran strong! First class operation! Highly recommend their business.
