What would You Choose and More Importantly WHY?

Let's assume the following senario: you've acquired a decent early A - say a Mordoor with no engine or transmission. It came with LBP discs and an 8.25 rear end with let's say 3.21 gears. You own 2 motors to choose from - both rebuilt - a 66 273/235 and a high performance slant from another car that was dynoed at 215HP. You possess manifolds and/or headers for both motors. You have numerous transmissions choices - both slant and LA 904s, 833 with both slant and LA bellhousings along with the parts to install either and finally an early Dakota A500 (you possess a slant to 727/904 adapter). So which would you choose and WHY?

I cast My vote for the Slanty & 4spd., unless You're really concerned about fuel economy skip the OD. I swapped one into My 383 Dippy w 4.89's (for obvious reasons) and
I hated it, shifted clunky and the gap in gears was noticeable even w/a B engine & those gears. My '69 Dart got street raced relentlessly, and every close race I won it was
grabbing 2nd gear that made the difference, I would almost always pull the distance on them in 2nd gear and keep it.
