Yes, the proper shift point is not necessarily at redline. I think you are right, a dyno could tell me more about the optimum shift point. I do find the power "feels" good at that 5500-5700 rpm.
That page has great info. I have refferred to it in the past.
My mod's are as follows:
Crane Hi-4 Ignition module, set full advance
S&S Super Carb(had a Mikuni HS40, but too many problems
Andrews EV27 cam
Screamin Eagle tips on stock cross over headers
50 thou shaved from stock heads, with high rpm springs and hi-po valve job
20 over bore for wear
I also swapped to a wide glide with a 21" on the front, but that doesn't affect dyno runs.
I have more compression than thier "stage-2". My cam has the same lift, but opens and closes earlier than the EV46 they use. My extra compression and valve job probably puts me in between the Stage-2 and Stage-3. So, the guestimate my mechanic and I have at about 80hp is probably reasonable, if maybe high by a couple ponies.
I had run a Crane 306 cam with a 2:1 Thunderheader. It ran wicked at upper rpms. The Thunderheader ran well, but was too loud. The Crane 306 came on at too high of rpm, ~3500. The stock header with tips and the slightly smaller cam puls stronger across the power band.
The Mikuni HS 40 ran great at top end, but had problems with casting ridges blocking the float, poor mileage, and nobody in the area who would touch or tune it. The S&S does not have the bottom end punch the Mikuni did, but is smoother across the rpm range. I also get better mileage.
It would be fun to throw a set of heads on it, but the $$$ go to tractor and property right now. My '84 heads are the least perfoming of the Evo heads, so I loose a bit there.
