Out with the 340 & in with the 410 stroker!
This is some good information and takes alot of time to put down on "Paper". Thanks for taking the time to share!
Oh, I should have those BOAT anchor heads off the Mock engine so you can play with them very soon.
Cool and thanks, it does take time... a lot of thinking about where to find the ultimate flow and yet not compromise low lift flow, I use up 4 hrs of a day real quick just doing a base test/port work & retest.
With the shape I have, it seems maybe the faster air is on the push rod side of the short turn, I widened that area by removing material from the PR wall starting right before the turn and rounded it more off the wall to the ssr. I was able to slow it down some and get it flowing past .480 to .510, also rounded the ssr peak all the way across.
No.8 flows to .510 and then saturates, but thats better than the full blown turbulence it had before where the flow dropped off. I done with that one...good enough and why wreck it now, Without pitot tubes...I shooting in the dark, it's real close to the max bowl diameter or at least in my mind 'playing it safe since I have $890 in these dinosaur bones.
Here are all the no.8 'problem port' #'s from 1st test to touch up and re test over and over.
intial port job-1st retouch-2nd retouch-3rd retouch-final conservative try
.100 64 - 63 - 66- 64.- 64--
.200 136 136 136 134 134
.300 189 195 197 195 194
.400 243 245 247 246 246
.475 264 266 268 268 na didn't measure
.500 254 258 257 266 268 peak
.530------------------ 265
.550 ----------------- 265
I just wanted the damn thing to flow to .500 or better, it does, done.](*,)
