Wanted to take a minute and share this. This is the second year we would be involved with the Gerald Lions Club Firework show. It takes a great community and alot of time & effort to make something like this happen. Glad to be involved with the Lions and helping bring events like this to our small community. Looking forward to see what the show and the future for our community has in store! Praise to everyone involved!

447 Cubic inch Stroker M' getting ready to head home. Tractor features pretty much every Aluminum and Fiberglass part we make on it. Been a fun project to do for a very patient customer. Looking forward to all the hot rods & pulling projects coming in the new year ! Thank you & Merry Christmas!

With tomorrow being Thanksgiving we would like to take a minute to thank our customers for the support over the last few years. We're glad to have been apart of your projects. I also wanted to use this as an opportunity to remind everyone that Thanksgiving is tomorrow, use it to spend time with your friends and family. With that being said Christmas and the New year are right around the corner. That means shipping and freight are going to get slower. We've had several people reach out asking about time frames on machine work. Whether you're wanting a head built for your pulling tractor or engine for your street rod. The sooner you get it in and get the parts moving the better, and the more likely it'll be done by spring time. Here's a set of 2.045/1.575 valves I was machining for a set of Stroker 243 heads this morning. Thanks for reading and enjoy the holiday!
