I have the old one (108 lsa) in my 9:1 493. E-heads M1 Holley throttle body EFI. It made over 500 ft/lbs from 2000 to 5000 rpm. Idles at 1100 with 8-10" vac in gear and sounds tough as all get out.

In my 4800 lb New Yorker it ran a traction limited 13.92 at 100.66 thru the muffs with an off the shelf 3000 stall TA conv and a 2.76 gear. That's the good such as it is. The EFI is not happy with it at all below 2500 +/-. With 76 deg of overlap there is so much exhaust reversion it never sees the same a/f twice in a row at part throttle. I believe the wider 112 lsa would solve a lot of that. All that being said your combo is 50+ cubes short of mine so it will just make all that low speed stuff worse unless you are willing to go with 3.91 or deeper gears and a big converter. Just for a comparison a buddy of mine has a 74 Challenger with a 452 headed 440 with the 484 cam and it runs 12.90's with a 3.23 gear and it has that "tough" sounding idle too.
