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.
