... hey guys, i've been tinkerin' with a customers HighPort project we have in the shop, and this head is the Standard pushrod location High Port and it has a "2.19/1.725" exhaust valve package, so far this is where i'm at with it, i know there is more in it, but for this port i am not allowed to add any material to the floor, so i'll have so save that for later ......

... the head was flow tested on a 4.310 bore, and the stock "Kauffman CNC chamber" has not been touched yet ... once we get back from Christmas vacation, i'll start on the exhaust port, but the baseline test of the "cast" exh.port with my valve job was very nice, so the exhaust wont need much work ... knock on wood, lol ...

(A.P.D.'s Kauffman HP)

.100 - 85.1
.200 - 154.7
.300 - 222.1
.400 - 282.7
.500 - 334.5
.600 - 367.4
.700 - 374.6
.800 - 379.4
.900 - 382.7
1.00 - 383.1

I always liked the respectable flow numbers on the High Port Heads even at lower lifts like .500, .600, .700 lift that the average guy might run.

The .400-.500 jump must be where the valve starts clearing the chamber? A little massage and numbers below .500 pick up would be my guess. Or is that made better with material added to short turn? Both?

[Kevspontiacs@aol.com]

must be a misprint, you said "vacation" LOL

nice numbers btw

[Hammertime Mike]

Nice numbers Bill !! That port job should make for a nice stump pulling street/strip motor.

Bill great work as always, really impressive numbers for a standard pushrod location smaller valve highport, should be even better with a raised floor once youre done with it. You always seem to do more with less, too bad everyone will say it wont make power because your flow numbers are too good! LMAO

What is impressive about those numbers and how is Bill doing more with less? Also why would someone spend the money to raise the floor for just a street/strip port? Show us a time slip.

Waaa Waaaa Waaa

[slowbird]

Seriously, why would someone spend the money on epoxying up the floor and raise the runner for a street/strip port? A lot of work for not much return, in my opinion.

[GREATGTO]

He hasnt raised the floor yet DS

Im fully aware of that, but he wants to, it seems like a waste of time.
What makes this port any different from SD Performance CNC port or KRE CNC port?

How do you know its a waste of time? Why dont you post those versions of the hp and lets see where Bills ends up when he is done, knowing him he probably did this port in a few hours.Probably his first time ever touching one too.

What much time does adding epoxy to the floor and then raising the rest of the port up take? How does does Bill charge per hr? The gains aren't worth it for a street/strip port, again that is my opinion.
SD Performance standard pushrod location HP head flows 393cfm on a 4.185 bore.

post the flow chart

[slowbird]

Call SD Performance

[BruceWilkie]

That was pretty much a valve job no??? Isnt this just his baseline???

BTW Slowbird your port wasnt proven, yet you still bought from Dan. Why is it anything Bill puts up isnt worth finding out more about??? I dont get where you think you are coming from. Can only your personally approved sources offer up info????

But thats ok its a customers head and it will do what the customer wants and run the way he has it built...whatever that may be. I dont know the combo yet do you?

I can assure you whatever Bill does, the port shape will be state of the art and be the best it can be, working within the parameters of what his customer will allow.
If customer allows he very well might weld up the port floor if clay or epoxy testing indicates a need to do so.

I'm sure Bill will post more information as he goes, dont mind slowbird, he always gets his panties in a wad over Bills work. If you notice he always seems to show up in posts where his opinion means squat.

If Bill got 380cfm with just a valve job on the heads, then my hats off to him. That is impressive. But I don't think that is what he did.
Nothing was said until GreatGTO made is usual BS comments so I asked what makes Bill's port different from the others already offered. I think that is a reasonable question isn't? And I gave my opinion about raising the runner, a lot of cost for not much return.

You know what they say about opinions, lol
I am sure that Bill's port will be nice.
