73 Dart Sport for Fun

Dyno day at IMM. Engine all finished up so took the short drive out to Indio for final tune and pickup.

Got to IMM about 10:00 Am and we got right to it. The engine had already been broken in and this is the last tune prior to delivery. The day began by switching out the spark plugs from the previous days run with a bit hotter plug and went on from there. Anyway, to be brief over the next couple of hours Brian and his dad Fred worked on the engine tune by tweaking a number of things. They switched out different ratio exhaust rockers, carb jets, plugs, ect. All and all pretty cool. So the SB 408 final numbers are:

C_TQ 522.12 lbft @4500
CPower 523.14 C_HP @6000

This is almost dead center of what we were shooting for.


Start to finish I've enjoyed working with IMM. When I first walked into the shop Brian sat down with me and spent quite a bit time making sure I was going to get what I wanted at the budget I had. Through the whole build Brian and I talked about the engine build, Mopars, my car, and gave me some good ideas on things I'm using on this car.
