[ugly duckling]

Conceeded? You don't know me very well Jeff. You questioned my integrity and I plan on showing you what my integrity is made of. I have no problem with you but you seem to always have something to say about me? I posted our head on this site and you questioned the advertised flow numbers. When ever someone ask anything about our heads, you throw a little slam in about us. Please try not to sound so innocent

[ugly duckling]

if you dont remember it was a couple of weeks ago on cal look i actualy complemented your heads and ended with a good luck. not once ever did you swalow your pride and complement the angle flow. not that i have seen any way. just rember this were your comp E ORIGINAL ideas came from and please dont forget it because it seems that alot of people do. any way i will say again good luck on your new heads. UD .

I like the angle flow head, the superflow and the comp eliminator. About the only thing a comp eliminator and a angle flow have in common is a straight intake port. I do not see anyone complimenting our street eliminator that looks alot like another companies head on the market, in fact it is our original tooling. I have a head at the shop that you should see Jeff. The head is a stock casting that has had a steel tube installed at an angle into the exhaust side of the head. Can you believe CB Performance made this head over 30 years ago? I wonder were the angle flow got it's idea from?

[ugly duckling]

i think the original design of the street elim came from the mid 80s JC HEAD and then everybody jumped on the bandwagen from there. ive ported street eliminators for people and thougt they were great for hot street or racing purps. as far as the angel flow design i aunistly think alot of people had the idea but only dean and ken in the begining made it a true realality show me one head thats been around for 27 yrs that remotly looks like it THERE ISENT.and still making major HP  to this day. UD .

[Trond Dahl]

Interesting to read about the history and todays version of your heads, but lets keep it nice and on topic please.
Since you guys are doing this as a business I think its only fair, and interesting for most of us here to see any flow numbers :-)

I think you are mistaken. The JC head came after the street eliminator head. I believe the first street eliminator was made in 1982.

I remember Fred Simpson schooling me back when he did a set of Super HOs for my 'super street' '67 more than several years ago ... it's not the top flow number, but what does it make @ .400" and under? ... Better yet, .300" and under? The valve spends a whole lot more time at that opening than at full lift.

Please don't jump my sheet, I'm no head porter , just a simple man with big ideas from the biggest state (Alaska doesn't count ... half of it's ICE! ).

I know what yer thinkin' ... big mouth too ... 

[58vw]

Mr. Texas Tom.....now we have a problem...i was born in Kodiak, Alaska......the BIGGEST state! 





kust kiddin ....about the problem that is

[TexasTom]

Mr. Texas Tom

Appreciate the salutation there Sir Tim!

Everybody's got problems.
Biggest? I guess we'lll find out for sure after the next pole shift ... !

The other problem, from my perspective, is we've got ourselves a fruit problem ... street head versus race.
Pick one via your application, I guess.

nice case...i wonder how soon i can get one of those? have some things i could put in and around it laying around

[TexasTom]

If, indeed, Darren did purchase the 'operation' & tooling for these cases, I wonder if the 'waiting list' was thrown in on the deal ... guess not?
It'd be cool to see some pics of one of these after being finish-machined to know or at least have an idea of what you may receive.
I'd be a bit skeptical to be the mule.

Let's see SOME MORE PICS!

Hey guess what guys - I have been playin with a 4" bore today 
 
(ok there were 8 of them  )

[TexasTom]

(ok there were 8 of them  )

Sorry, but unless it was a dual engined, horizontally opposed VeeWee ... 

[SlingShot]

Saw this on Samba, pretty cheap. Didnt know guys were doing these 4in Bores out of Mag cases.

[Fiatdude]

I got to fondle a 5+" Bore x 5.5" stroke engine ===== 924 ci

Boy it was pretty -- -- $75K worth of pretty

I couldn't afford the carbs on it

Here in Sweden 4"+ magcases have been done for a long time, the engine builders use steel plates to do this.

[Steve D.]

Yup, 4 inch bore motors don't work on the street and I have the proof- I drove around the Fullerton/Orange area for over an hour this weekend in stop and go traffic and didn't see one of them out there...

Except me and my 170"s of naturally aspirated A/F GRUNT bouncing off the walls throughout the DKP Christmas cruise.  Car ran flawless, oil temp didn't go over 180* the entire trip- just me, some cubic inches, and a pair of IDA's sippin' on 91 unleaded rolling around the streets of socal with a sea of vw's.

Can't wait until next year!   

[ugly duckling]

hey steve do you think you could fry me up some bacon an eggs with those EXTREM  OIL TEMPS your runnin there im feelin HUNGY oh thats right i forgot i like my FARM PRODUCTS WELL DONE will leave that up to some one else .   if you dont watch it your gonna break the heat thermom with  those BLISTERINNNNG temps .

Steve, are your IDA's just 48mm? or bored?
What times did it run on the 1/4?
Sounds like you've got a real sweet combo there.
Thanks.

Video?

Yepp!
I saw a Rallycross engine with Angle port heads just when they were new (mid eighties?) on mag case with steel sides and 103 mm cylinders. Pretty nice engine with oval exhaust pipes in the bends to keep gas flow at same throughout ....some theory I thought he had picked up from F1 but not so. Never saw that again but it did trigger my mind. Was a hell of a work to do. You cant buy those bends in the market.

[Steve D.]

Jeff, I'm all out of bacon- you know food doesn't last long around this place 

David, carbs are just bored out 48's to 51's, no fancy boosters, profiling, or stacks- too rich for my blood.  Haven't had it down the 1/4 mile yet under power, critters in the carburetors shut down #4, but with four passes on the car it's gone 7.80 @ just under 90mph in the 1/8th @ 1950lbs w/ me in the car on D.O.T.'s- no jetting, timing, or tire psi changes.

Tim, what kind of video do you want?  I saw one the other day with a chain smoking panda, that was pretty cool....?

[58vw]

im still waitng on the video that is going to bite Jeff in the ASS.....tick tock...thats what video...but the panda thing sounds kinda cool

[Big Power]

Sorry for the late video. I have been pretty busy shipping heads Also, I thought about being nice and leaving this all alone but since you two asked for it , here ya go. Some fine Farm raised heads for you Jeff. BTW, This head is 94mm bore, flycut .150  As you can see in the video, the test pressure on the gauge is only at 24.75 inches, flowcom is reading 25" We are waiting for a calibration kit to arrive from Superflow to get the motor controller back up to 25" Being like it is at 24.75, we are short 2-3 cfm on the flowcom from what the head really flows. BTW, Jeff and 58vw, this head is at 103.39 cfm per sq.inch of valve surface flowing through the manifold. Pretty efficient compared to your work. Have a nice day boy's.
