1/4 mile times

Read this thread from Moparts. There are some cars running pretty good with a smooger 440 engine.

I still think not enough converter for the 509 cam. The 484 would run better in that combo and is better cam pretty much the entire RPM range except the last 500-600 rpm. Seen it too many time when somebody "upgrades" to the bigger cam using the same converter. I'd get something that flashes to 4000-4500 range.

I wouldn't bother with a 3.91 to 4.10 swap. 4.30's maybe, not enough change on the 4.10's

Tuned up right it should be capable of 112-114 mph.
