I wanted to share a little about who I am. My name is Steven Whisnant which is why I named my business SW Performance. I have always been a dreamer and thats why I went with Superman and Wonder Women for my logo because as a kid boy or girl they are great role models to look up to.

I'm a second generation racer/ engine builder. I'm so thankful that my dad who has passed on now taught me so much old school technique about building engines and working on cars in general. I have been building sb/bb chevy engines since I was 14 years old. When we started JR dragster racing in 2012 I never wanted to mess with them and finally my dad talked me into doing our own in 2014, and I'm so glad he did!

I have 2 boys Cam and Gavin Whisnant and they had such a great jr career! They went to well over 200 final rounds and around 130 wins between them both. They both got out of jrs when they turned 16 and started racing big cars and both have had some fair success these past few years with Gavin winning the main event bracket finals at 16 years old in our dragster being the biggest win!

My business is jr dragster engines but I also build small and bbc as well. Going forward I'm looking to build my jr business up more and more! I have so many companies who I rely on and I couldn't do it without them Nichols Engineering, Blossom Racing, ARC, JR Race Car, and Pickens Metal Works, I sincerely appreciate them so much!

I attached just a few pictures of some of our memories from 2012-2022. We have had so many great memories and met such a big family in drag racing and will continue to do so!

Also wanted to say how much I appreciate past, present, and future friends and customers for supporting myself and my family!

This off season I was so blessed that my friends and customers trusted me with brand new builds, rebuilds, carbs, clutches, parts etc!

I'm EXTREMELY grateful to each of you! I have tried so hard to get each project back in a timely manner and it was a challenge being just me in the shop and I appreciate the patience of each of you.

These pictures are just some of the builds since January and I still have a pretty big back log trying to get everyone on track. Please reach out if I can help any of you guys in any way! I'm looking to continue to grow and look forward to the opportunity to help each and everyone that I can. Thank you all so much!
