Yup! still got the penny. The pics above were of Gary Wells intercooler on his white limited. I also ported (myself) my V4 SLIC on my mid ten second GN.

Ok guys
I went back out to Richards place and did some more work on Mark's HA intake
flow numbers
Mark S (84/85) HA
1-134 2-148
3-153 4-117 -----124 after doing some extra porting i ported it the best i could get to without cutting it open 130 Cfm. But other wise it's still a complete intake zip tubes and all.
5-156 6-146

Nice test.
I would also post if the intake was ported to a 1200 Fel-Pro gasket or the stock valley pan gasket.
I would also try to ahold of a Stage 2 intake. Sorry I don't have one.

i think i have one of those in the shop------i will check this weekend
did a champion "biggie" that was ported by GBP----------had champion plenum and accufab throttle body
total flow was a whopping 784 @ 28"
average port flow was 283 CFM
277 #2 #1 273
285 #4 #3 288
289 #6 #5 289
Howdy guys
Well i fianlly got some more time to spend on Mark's HA intake. I finally just cut the bottom off of it. I now understand how the Zip tubes and air flow paths really are.
So i using a milling machine i milled out the center divider and the zip tube walls. The cutter i was using didn't allow for me to mille the center divider wall completely out. But it's about 3/4 of the way down.
The champion intake has it milled completely away.
The final flow #'s are
1.---187 2.---187
3.---188 4.---193
5.---188 6.---187
Avg Flow 188
When i first started #4 was the worst flowing and i actually ported on it some more and got it upto 130 before cutting it open. Now after i milled it and ported it it's now the best flowing lol. I actually cut thru on a small portion of the #4 port on a sharp edge that i had to weld up and shape back down.
The other's i simply just touched up on those over what had already been done.
The next HA intake i do i'm simply just gonna go ahead and cut out the zip tube and center wall. Then flow it and then port it accordingly. Since i now know what needs to be done.

over the holidays Jim managed to find his hemco plenum so we set out to flow it on stock intake to see how it compares to the rjc plate or a 1.5" spacer.
