Different evaporation rates perhaps. Some might have evapoarted thus skewing the results. Maybe someone put a LOT of graese on the plate to seal the chamber, while the other tester used very little grease. The tempertaure of the liquid even makes a difference.

I have used transmission fluid in the past. I just used plain old water this time, I didn't want to have to clean up the burrette. I used minimal grease and held pressure down with my hand to help get a more acurate reading. Good idea with the port volumes. Might have to get after that.

225cc a.f.r's all tha way..they flow 320 on intake at .600 and 250 on exhaust.. darts only flow 313 at .600 on intake and 214 on exaust.. i think a.f.r's are the best choice for a radical 346..

Woodywood - Thanks for bringing this one back up. I forgot about it. I did the cc's on the runners, just forgot to post them. They were both in the 195cc range. I'll get them posted when I get home.

6.0L 817's I- 199cc E- 76cc
4.8/5.3 862's I- 195cc E- 75cc
Not a whole lot of difference in size but the big gains must come from port shape. They both had similar amounts or carbon build-up. I cleaned the majority of it out. A freshly vated set may show a couple cc's more.
