Vic, my sim shows you go from your:
4000 rpm converter(baseline)
good air = -500 ft DA
100 ft track
1.52
11.32
119.8
Increase the converter to 4500 rpm
1.49
11.21
120.2
I don't know if this is accurate, but it looks like it thinks you'll pick up a tenth loosening it up another 500 rpm. I then thought, if some is good, more must be better, so loosened it to 5000 rpm, but it only showed an 11.20 then with no improvement on the 60 ft or mph......
The above is with the same efficiency for both stalls in the simulator. Your 4500 rpm might actually lose some efficiency up top and the gain could have been less..... I dunno.
Just for fun..... don't bank on it.
good luck !!

However, there was another thread similar to this one with a different engine equipped with a solid roller cam that spun up to and above 7000 rpm that might be on the brink of what you would want to do with it, but, in my personal opinion, engines are a bit more resiliant than what many believe..... its farily rare to hear of a crank cracking and even nowadays you do not hear about rods being thrown very often. I personally however do recommend a good forged piston for everybody that plans on racing their motor, but thats debatable if its necessary. But, I have my own reasons for believing its money well spent.
