If you decide to do another motor.....Pick up a Mopar Action "mopar tech special" 1995 where they built a 451/400, 727, in a 72 RR with 3.23 gears. The car licked off a 13.50 in the 1/4. Car had huge amounts of torque. Fully loaded car with A/C. Cam was an MP 284/484 hydralic.
You can find this on a CD too by looking at a link here on moparts.
http://www.moparaction.com/Tech/archive/Beeper.htmlI don't know how much it would cost to build a stroker 451, but I'd think you could do it pretty cheap with the availability of 400's around and a good used 440 crank.
I know there are some PURESTOCK guys running mid 13's with some 383's and 4.10 gears.
