Just in case you do:
I used the unported EdelRPM+4hole spacer as my BASE, Jay got 402ghp for that one.
I predict the early iron is -18hp from there
I predict the "S" iron is -20hp.
I predict the "T" iron is -24hp.
See if you get the same measurements but I have, for port size and "A" and "B":
Early: 2.06 x 1.12, A=3.50 B=5.13
S Iron: 1.75 x 1.13, A=4.00 B=5.75
T Iron: 1.75 x 1.13, A=3.13 B=5.00
If you guys be gettin on a little in years like me, just be sure you stretch good before hefting that 80 lb of iron, my wife is always demonstrating new "stretches" she has learned. I try to do some of them, it helps.
There are almost NO dyno tests with the old iron ANYWHERE, these would be really classic tests (for the book, hint hint...)
