Maxwell Dodge on 620 just passed 183 across from the Walmart.You get to also look at all the B@D@SS Vipers they have in the shop and floor room
Plus it is very close to my house so I now go there.
They built this DYNO shop for the Vipers, but it is always nice to show those boys what a little 281 can do
Let me know when you can go or want to go, because I also want to dyno now that I got my fuel system problem fixed, but 1st I will need to get the A/F checked on the wide band before I go.
Another option is Colvin's Automotive around MO PAC and 45th.
Colvin's would be your best bet. They are on Hancock Dr. It is usually something like 50 for first run/setup and like 15 for additional runs without air fuel.
