[quote=I attested that my 194 head made a huge difference in power
1/4 mile times & racing against my friends v-8 cars proved it.
It was the fastest my 250 ever ran normally aspirated period.The chamber walls were not touched for any unshrouding,1.85-1.88" intake valve size I used,(it's been a while)
I still have that same cyl head if you want pics of the chambers?

As you may know I am trying to match what is going on here with my computer program the Gonkulator. I fully agree with you that you can't go by any single set of data - they all add up, and different things can affect any given test or test series.
If you have a picture of your 194 combustion chamber as mentioned above and can post it or email it that would help.
Also, your Camaro seems to have run good - it's hard for me to get my computer to "run" that fast. Do you recall any of the following:
On the 14.25 run (4spd) - MPH? 60ft?
On the mid-13s run (auto) - ET? MPH? 60ft?
I assume those were raw, uncorrected times?
On both runs -
3300 lb w/o driver? Wow that is heavy, just confirming.
Open headers or can you describe the exhaust?
Cam specs, I had 230-230 duration for your cam, not sure if a guess or prior post, is it 230-230 or 236-236? Confirm other specs?
What I do think is great about these sometimes fiery threads is, they sure show the continuing and detailed interest in this old siamese-port iron. That is good!
