A few things have gone through my mind. The weight of the rotating assembly and the length of the stroke. I've had 383s that had better throttle response and low speed performance. I've thought about advancing the cam. I've had good results with that in the past. It's a heavy car and I'd like to keep the 3.54 gear in it. That in itself presents a bit of a challenge. In this situation it seems like the automatic is more forgiving. Anxious to try some different things and hoping to get the chance soon.
Where have you been brother, Lots of input and some questions to help.
But you've been
I guess.
Don't worry about the rotating assembly or stroke length.
That's the Hard stuff to fix. Even with the best tune the 253*@ .050 cam is going to be a dog below 3500RPM, with a stick, Well unless you dump the clutch and let her rip.
With a high stall vert automatic you can make it work. IMO, a smaller cam change.
But it looks like you've decided to bow out of this thread.
If your tunes fine, Cam change is your Best bet.
Rotating assembly, stroke length. Shouldn't even be in the mix of thoughts for your fix.
