MorSpeed Manufacturing Inc

We at MorSpeed are so excited! We are within weeks of moving into our new shop. This will make production much more effective. David Warren can now work even harder at production for our sister company . Steffany Fenn and Camille Warren can now do more manual labor, Chris Fenn can now work 2 jobs and Tony and I are training James “Jimbo” Fenn how to be an awesome supervisor just like me!

Did you know that there are only a few manufacturers that can legally make and sell the Twin Blade patent carburetor main body? We are one of those companies. We manufacture and sell them through our sister company, Tony Morris Carburetors. Come check us out!

We are at Bradenton Motorsports Park today! The weather is incredible and great racing conditions. Come by and see us if you need anything at all!

MorSpeed and our sister company TMC Carburetors are represented at The US Street Nationals by Dave and Vicki Fulton and Chris and Steffany Fenn. Dave is running the Fulton/Morris Monte Carlo in the 6.50 class. Tony and Teri and crew chief James Fenn are in Gainesville Raceway running the first points race of the year. Come by and say hello or chat!

We at MorSpeed have been busy supplying our sister company TMC Carburetors with parts for a big order for a customer and friend. Thanks to our whole crew for working long hours to get it done!!

We at MorSpeed are getting very excited. Our brand new shop will be done this next week. Stay tuned for pics.

RIP Terry Phelps

Yesterday we celebrated the life of a dear friend Terry Phelps, Tony met Terry when he worked at BLP Racing Products and ended up working under him in the carb department. When he moved back to the machine shop he helped Tony learn all the ins and outs of running the carb department as the carb shop manager.

Terry was also instrumental in helping establish TMC Carburetors and without he’s help it simply wouldn’t of got of the ground, Terry would manufacture the products for TMC and together they would improve and develop new ones.

Terry raced back in the day in go carts and road racing, also working for Bo Laws Automotive in Orlando in the late 70’s though the mid 1980’s helping develop products like the alcohol carburetor and belt drive fuel pumps among other things, then moving on to open his own machine shop. Bo Laws would later purchase Terry machine shop bringing Terry back into the fold and into the BLP family.

Last year Terry took Davey Warren III under his wing and mentor him, passing on all his knowledge, in his words “I don’t want what I’ve learned to go to waste.”

We will continue with Terry’s legacy with Morspeed Manufacturing and we hope we make him proud.

I more qualifying run then Round 1 today. It’s a beautiful day at Beech Bend Raceway. High temp is 85 humidity is low (for us) and we are ready to turn on the win lights! TNT Racing is back on the track!

Congratulations going out to Lindy Herman, who took TMC team mate Stewart Herman and his brother car to the final and placed the Nova on the dance floor!
