The Black Cutlass was fun to race and to cruise in, and I thought 1 chance in a million it might have wound up with you in its journeys. It had distinctive 5.00 gears in back, 3000 stall convertor and headers fed into 2.5 36 inch long tube glass packs from NAPA, for the street. Outside the deep chrome wheels and large tires on the back the exhaust was the only sign it was not a totally stock 350. The Holley electric pump back at the gas tank was switched on only at the last second for making a pass otherwise, as it ran off just the engine's mechanical Holley feeding the Quadrajet the rest of the time.

Glad you found some fun with your dark green ride.

 

Thanks for kudos on the Stroker kits Pete.
I’ve looked at all your info and your results could be more typical. As Velcro said, maybe your heads were better than I gave you credit for. My apologies. I’m a fan of pipe max too, and those numbers don’t seem too far fetched now that I’ve looked at it again.
And for the last time, my criticism of Bills Dyno pulls center around one main thing. Who is able to run their STREET build at 130*, really? Oddly enough when he did an alcohol engine he ran it at 160*, hmmmm. So again my main point is and always has been, why are you running street builds at such cool temps? Because they make more power there. And if someone takes it to the track, and doesn’t back it up with a corresponding time and speed, they can always blame it on the driver, track conditions or whatever.
Again Pete, nice build, and thanks for the explanations and favorable mention on the kits.

I think you are...............your both stuck in the 11s LOL

 

This is the very reason some dislike you.

 

Maybe 🤔 😂

 

Holy cow 🙄

 

Mark Cutlassefi how does it taste.

 

Thanks for the heads up Dale.

 

I appreciate that, but I won't take credit for the port work on these heads. These #5 Iron heads we're ported by John or his Dad over at Rocket Racing at some point and were in good shape. I would have done a few things different and wanted to touch up a few things, but decided they really didn't need to be touched other than fresh seals and a light cut to make sure they were flat and smooth.

I didn't remember what your criticism of Bill's pulls were, but yes, making a hero pull with cool water temp seems to be something every dyno operator likes to try. I personally prefer to keep them 160ish.

In the case of this 434ci Street build I did, water temps range from 150-172F, and that's fine with me. Obviously in the car it will run warmer, but with the iron heads and 10.53:1 on this build, risking a customers investment on the dyno that loads it much harder than any street tired car ever will is how I prefer to do it.

Making pulls on an engine on alcohol @ 160°F is pretty normal, if not hotter. Cold alcohol engines don't live long.

Here's the thing about your average street car, and I'm sure most people understand it. They just aren't that serious about racing and low ET's. The driver rarely goes to the track, has zero or little idea how to tune a car with repeatable results for verification, and has little understanding of suspension setup, converter, gearing, etc. And honestly at some different point for everyone the appeal of go fast at the track is less important than being user friendly.
My wifes 1970 Chevelle is something of an example. The engine made about 685hp @ 6500 in the configuration it was in the car, it has a 8" 4500 Coan converter in it, 3780lbs, full exhaust with tailpipes, child seat in the rear, etc. and it's only gone 10.92 @ 124.7 mph. It's handicapped with a 3.31 gear because she likes to drive it, and 2600 rpm at 60 mph = 10-13 mpg. Now the Moroso slide rule shows like 560hp for the weight and MPH. Doing a little math (124mph x 3.31 gear x 336)/ 27.5" tire = 5014 rpm. Add 300 for slippage, so 5300 rpm through the lights (which is roughly what she saw) corresponds pretty close to the 534HP observed / 575HP corrected @ 5300 on Steves dyno in 2595 DA. It can certainly go faster with changes, but that's typical IMO of most guys with a "street car".

 

Great!!! And I would expect this from you anyway so no problem.

 

boy this didn’t age well did it?

broadly claiming another builders engine has inflated numbers without knowing the head flow specs or min csa and saying a smaller cam at .050” should make less power is pretty wild.

these two engines have more differences than similarities from what I can see now.

the only thing the same is the stroke.

 

I’m not sure some on here actually understand what pipemax is.

 

I'm aware of the program, and Milan used it extensively back in the day, probably still does. He always made big power.
I agree with the assessment of how most street car guys use their car; maybe I'm a knucklehead that wants to get repeatable results at the track? However, as mentioned, there are compromises to make in most cases. A good drag car doesn't necessarily make a good street car and vice versa.
​​​My goal is to lay down the best number I can get, mainly for bragging rights, then be able to short shift my way to a (safety) legal, repeatable number.
It's a great feeling to roll in, unload the trunk, air down the tires, on pump gas, and be in the bottom half of trailered cars on race gas and big slicks. Then, load up, air up, and drive home an hour.

 

Pipemax is a collection of years of engine builds, head data , header data, camshaft etc.

Not just from the the guy who designed the program, but from many many builders around the world. He continually updates the algorithms when an engine falls outside(above what pipemax says is max)the pipemax numbers.

So if your build falls within what pipemax says, you’ve done nothing special or unique, what you’ve done is build what somebody else already built…you copied someone’s build.

a long time ago on Speedtalk guys were trying to use it as the gospel for comparing EMC type builds. It didn’t work and made no sense at all AFTER the fact when actual Dyno data from builds were plugged into pipemax.

to his credit, he said it wasn’t designed for that type of build. He asked for data from competitors about their builds and adjusted pipemax to make it better.

 

 

You can ALWAYS have a lot of fun sandbagging and playing the stripe. Chasing is WAY more fun than being chased IMO.
Just invest in good brakes.

ive won more races in the 11’s than you can count. But hey, whatever makes you sleep at night

 

Why Milan is mentioned in this or any post is disturbing. He’s a ******* Dick

 

He's a dick also !
Who do you like ?

 

As far as I know Milan's full weight NA small tire Olds using a production block is a top performer for its type.

 

Millan was a regular contributor on ROP with dyno and track data backing up his builds. One or two members are running his engines both builds are impressive IMO.. Millan was one of the first to show how well the big block Oldsmobile head responded to a larger intake valve with out any other other modification.
https://www.tapatalk.com/groups/real...ted-t2913.html This was the stock head build with just a larger intake.

 

I'm glad you enjoyed it, I get indigestion every time not one of my personal favorites.

 

Just for the record, when Milan was running either 9.3s or 9.4s @ 3340 with a aftermarket head I was paying close attention because he was close to my 9.2s @ 3580-3600 pounds with a production oval port head. His dyno testing was done on a SF 902 and he did not show dyno HP, but was not far off, now maybe he didn't get into sea level conditions, my runs were made @ 615 DA. Anyway I became a fan of Milan because obviously he can get it done, and he was into running fast NA at full weight on a small tire, my passion.

 

he could have the fastest car in the world…. He’s still a Dick

 

In the more modern day builders he might have been the one showing the gains, from the larger intake valves, but back in the day Valley head services installed BBC intake valves (2.19 or 2.25 and I think 2.25 stainless) into their all out ported Olds heads, with a smaller exhaust valve in them, by the mid to late 1960s. And I didn't read this in a book or off the internet, but was there when they came in off the freight truck from Larry Ofria. Remember they will tell you I don't know a thing.

Thanks for the reply, Cool piece of history. I'm sure others have done it before you just don't get to hear about it. Milan was always willing to share his builds and what he had found. What I like about what he had done was the larger valve was installed in an un-ported head, so you got to see what the valve was worth on its own.

 

Can you post some of his builds on here?

 

The pictures are no longer up on Realodspower and I lost all my saved pictures from that time period. Maybe someone that knows Milan will post up some pictures.

 

The sight of that huge stainless intake in the Olds chamber was something to see, and even more so especially with the contrast of the small exhaust valves. The heads were flowed in the 1980 when some new owners bought them and took them to have them flowed. The flow bench showed them flowing on par with the stock BBC Chevy heads. This disappointed the new owners who knew little about Oldsmobiles and how much they would flow stock, until I explained it to them. And pointed out our Oldsmobiles of the past that killed so many BBC cars were running stock lower flowing heads, as the rules required. Those ported heads from Valley we had on a 425 Hillborn fuel injected fuel altered. About 4 or 5 years later Ronnie quit his day job and opened up a NAPA store here, with a machine shop in back. Where many a hot engine was built and heads ported. We also resized connecting rods and aligned bored blocks LOL

Thanks again for posting very cool history. Do you have any pictures from that time period?

 

I am very well like, in most circles. And speak my mind, call them out like I see them. Good or bad. Not sorry, it does not fits your narrative. Speak directly and bluntly; spade is a spade! It's the NYC way.

 

I wish I had some, and the home movies I know a few people were taking back then, but I am afraid they were lost to time including those that took them. Even those people from around then are almost all gone. Pictures and home movies were not the norm, as much back then as they later became. Even the trophies won were not usually kept for long and media coverage was basically non existent out here even when the Nationals were held here or world records set. It was just another glorious day and we were all much younger living out our adventures. To us it was just life. It was kind of like all the girls we knew. Memories but few pictures.`

 

wow, that’s amazing
