VR-200’s…… AGAIN…….

-
Our AMX with the Bloomer heads, low compression 11.2 to 1, Crower 31409 solid roller cam, 4.125" stroke, 6.200" rods, Super Victor intake, 4.030" bore, 1040 CFM APD alcohol carb, Coan 8" converter, TF904 trans, Star vacuum pump. 5.84 in the 8th @ 116.6 mph 1.23 at 60ft. while weighing 2870 lbs. That's moving pretty good for a conventional head with a push rod pinch and no offset intake rocker arm.
 
Man it would be fun to throw a set of those heads on my ole iron head 360 backup mill. 13 to 1 KB piston stock stroke 360. Time slip pretty typical in Vegas. 1980ft actual altitude. 2944 race weight.

Just thinking this over, the only reliable , can't lie is to take a known sorted out, legal race car, like a record setting stock class car, and put those heads on a good shortblock with a great level of prep and let er rip. Then look at weather corrections, tire type, trans, etc . And see just how well the heads do. The problem remains of just how well joe average customer will use those heads though. Case in point. Me. In a course of 24 years, using 440-1 heads, i moved from about 725 hp to 926 hp as i went through different levels of prep and porting, shortblock, compression change, i got more and more out of those original castings. And a good friend is closer to 1,000 hp with the same head. So i get thier reluctance to post anything but track times.

As far as I can tell, there are like basically 3 cars brought up like clockwork in these bloomer head threads. ALL of them are EXTREMELY well sorted and prepped race cars. Does that mean anything? Grain of salt to me.
 
Well in my case I don’t have the proper converter for our small mill hence the terrible 60 time. It’s the 8” that we run with the w8 mill. At least the data would compare :). Just spitballing, but it’d be fun.

This is another test engine that I built to prove our VR-200 cylinder heads. It is a 416” (stock block) with bushed lifter bores and billet (center three) main caps using our VR-200 cylinder heads on pump gas, in a real streetcar. I personally built this engine to put on the dyno and install in a car for REAL WORLD results. This engine made pulls on the dyno as well as tested in a 100% pump gas (92/93 octane) car. The test vehicle was a 1968 barracuda street/strip combo with a flat hood and weighs in at 3315lbs (with driver) running through exhaust. It utilizes a 904 trans and 4.10 gear on a 275/ 60 tire. I believe this car has the potential to go 9.70’s with a hood scoop and a slight converter change. Just another testament to our VR-200 heads.

Thank you,
Rod

Doesn't look like a well sorted strip car to me, it looks on the porky side, a street strip deal pump gas 92/93 octane.
These heads are breathing much better than your average ported seedblaster head.
 
typical mopar car guys. here is a perfect example of a head that is obviously making more power then the other heads. if it was the trickflow head, everyone would be jumping for joy.

the AMX is proof that these heads WORK....... PERIOD. to even argue this is stupid.

Absolutely wrong take.
1. The street car Barracuda mentioned is just that. I believe Rod actually loaned the guy the motor to stick in the car just to see what it might run, what he didn’t mention was there were teething issues the weekend the car actually went to the track to make those passes. Afterwards the motor was taken back out. It’s was definitely not a proven car or driver.
2. The blue 71 dart was a new build this year, first time out ever was with this new motor that was a father/ son/ grandson project.
First time ever competing in drag week as well. car has competed in just a few times this year in its life. It also has a power eating turbo 400 in it.
3. The AMX has the biggest chance of fitting your notion. Not sure on how much that car has been raced, how long he has had it, etc.

Ya pretty much my thoughts. The only car that is a sorted out combo is the AMX. It runs 9.20’s which I have yet to see a TrickFlow head run that fast.

There is plenty of TrickFlow headed strokers out there running mid 10’s. Not one have I seen run 9’s like the Bloomers have.

One member sent his trickflows to get hand ported and he didn’t gain much and didn’t run in the 9’s.

Could you clarify this statement for me? I just want to make sure exactly what it is you're saying here.

Thanks,
Rod

Even my pooch(3330 race weight) street strip 69 Dart with a dinky 565 gross lift flat tappet cam runs 10.20’s at 130+. And my vert flashes below 5k, know it’s off a good bit.
I would bet any amount of money swapping to the same mild roller two of those 3 cars are running would dip into the 9’s as well. Easily.

Our AMX is well sorted out. We've worked really hard on it. But it's still really just a low maintenance braket car. It's not maxxed out. It's got relatively low compression at 11.2 to 1 and an OOTB intake manifold. With a ported intake and 4 full points of compression. It'd probably make another 30 to 50 hp.

my thought was that if the track times are really good for what the car is prep wise, then you can figure the potential of the heads is good. But it depends on if they are properly used. If you stuck the 440-1 heads i made 926 hp on a 383 with a juice cam, and 9/1 compression, it would be a pooch.
 
i don't know what's so hard to get, these Bloomer heads are making street cars dip into the 9's. i can't think of a reason to doubt these heads.

I don't get it either. People say they want a better alternative to what's currently available then, I show them the difference and this is what we have. If someone has had better results with other heads cast like these, PLEASE let me know. I have shown 3 separate examples with the weight of car and actual track times. You know...... the **** that actually matters!

Thanks,

I don't understand either. If there is was something that pittsburghracer showed us is that a good set of ported heads can do a lot. These heads are what John was trying to achieve but these are CNC so they are all the same. If I was chasing a number I would not hesitate to buy these. In fact I hate reading these BPE threads because every time I do, I have to talk myself from buying a set.

I think John's porting program was better than CNC

Not enough ( if any) on track results to say that.
Numbers are numbers. Track results and mph trump anything else.
The Bloomer heads are CNC, but from what Rod told me, these CNC heads almost exactly show the same numbers/ results as the finished ported head did.
In other words, the cnc result almost exactly mimics the head they were designed from
 
I read these threads cause I'm curious, and impressed.
But I'm a big block guy. I wish Bloomer would do some speedmaster big block heads.
But unlike the young guys on here, low tens would be fine for me.
Been nines, it's fun, but expensive. Low tens are easier/cheaper.
(Especially now that my local track closed, and the nearest that I can use is over 125 miles away. F#@k you, nhra!)

That is exactly where I am. He I seriously doubt will do anything big block.

John had plenty of track results running mid 9's with ported Edelbrock.
The fully ported speedmaster he was working with had better numbers on the bench. It's too bad he never tried them at the track.
We all know John was a track result guy, wasn't into dyno numbers.
The BPE head is the real proven deal. imo no doubt.

If I want to show what my parts can do, I'm not gonna put em in some garbage car. What would be the point?

Offset rocker was used with those Eddie heads. John moved the pushrods over and had to get a custom rocker made with his offset.

Not in the same category as a standard pushrod location head.

I wouldn’t say he had plenty of eddies heads running 9’s, his was the only one.
 
"If someone has had better results with other heads cast like these, PLEASE let me know".

Pretty much what I thought..... CRICKETS.....
