I saw a dart run a 10.38 the other day with a small block and a 904 and he has been running it for 4 years. 904's are no punks if they are build right.
I just got back from the test and tune tonight and I bet there was a dozen old mopars at http://www.mokandragway.com/ next weekend is the all mopar event I'll see if I can get some pics Saturday. They were running good all night also.
