UTG wins!

Not much you could have done, a 340 is destined to be a turd in a E or B- body.
The power to weight ratio isn't in favor of the 340. That's where the torque of a B or RB comes into play.
The strongest 340 I've been in was in a tank of a '73 charger with a 727, 3.55 gears, and a factory MP high stall converter. The left front of that car was still rising at 95 before he let off of it. It freight trained from the second he got into it until he let off, just violent but seamless acceleration from start to finish.
