In my name I think you can understand. From a 2800lb bracket car winning races and championships, to the most durable combination i have ever raced. My 471 in a 2800lb a body won. And won often. 500+ runs and it put in work until I decided to change racing genres. That engine is still running. Koffel ported and built B1 originals.
I worked at a CPD dealer from 85 to 89 and was the “Direct Connection guy”. You are definitely right about Mopar peeps being hardcore ( or is that hard headed ?).
We probably won’t see any higher development of the wedge head design past the Predator heads. Anything like that already usually requires a Hemi block, so going to one of the Hemi type heads is usually the next step in the progression. It would be interesting to see what a set of Stage V Millennium Hemi heads could be made to flow in comparison to a set of equally worked Predator heads.
Finally another mopar head. Love it. My neighbors I race with have 2 sets of these and the B1 MC heads. They're all bad ass for sure. The Brodix makes the best original inline valve configuration wedge mopar heads no doubt with the B1 PSO and MC. The next step after the B1 PSO for a "wedge" design is either the B1 TS or Indy Predator but they're a canted valve design.
These brodix heads look great. For a Mopar guy wanting a more budget-minded big block with 600 street-able HP, the Trick Flow 240 and 270 heads are hard to beat though. These Brodix B1s are in a different class though!
TFS 270 has a big valve seat so it might take a bigger intake with a smaller exh valve. If the casting allows for a bigger throat and bowls and some additional porting, it would make a great head for up to 800 hp if used with a 4.500" bore. Maybe 900 hp or more with all the tricks. I'm done building cars, but I'm still intrigued by ancient tech pushrod engines. BTW, I think Dave Koffel did a fantastic job developing this head, but it's been around since 1992. The B1 PSO has always fascinated me, but I have only seen hi-def pics of them fully worked by Tom Hemphill(RIP). I want to see a 1350 hp inline wedge engine NA on gasoline, but no one is going to put up the cash to attempt to develop such a piece. That new Indy block in high quality cast iron with the BBC bore space should provide an adequate foundation, but a W8 style head for a BBM is simply never going to be cast, and I suppose a billet head with water jackets could be done by Visner or Foltz, but no one is going to put up $200k for a BBM.
@@Torquemonster440 Yes Sir, B1 originals part# p4349600 I bought them back in 2007 off a friend that stepped up to the Predator head. Thinking about doing a set of those next.
Some 25 years ago because building a pump gas engine, I thought the port was too big. I asked Koffel for their opinion to raise the floor some, and they said it would be ok, but they told that it's very important to retain the odd shape. Said that it's for wet flow properties. I didn't do it after all, but the heads and the engine still worked great. I have flow sheets of maybe ten sets of B1's, and your numbers are pretty decent. There are better heads out there, I have FBS heads and they flow 440 with the same size intake valve and much smaller port area.
In the inline valve B1 world, the pecking order is..... 1. B1 PSO 2. B1 MC 3. B1 Original By the looks of the valve size and flow numbers, looks like you have the B1 Original, since the MC and PSO versions typically use a bigger intake valve, along with a number other improvements and move far more air, typically between 450 and 480 cfm. The B1 TS is the top of the line for the B1 series, but is a different configuration altogether. Unfortunate, these are all a little long in the tooth and in the case of the B1 PSO it can't even be purchased until Brodix has orders for a minimum of 10 heads, if I remember correctly. As for anything even remotely current, the only real upgrade for 440 engines is the Predator head.
You should do the B1 small block heads . I have had some good results with them. Fully ported with 2.055 i got 308cfm . 318 with 360 crank in 3500 lbs car first run out 11.005 120mph definitely a 10 in it. Just started on a set of B1 bamc heads.
This might be off topic, but what would happen if you lightly stoned over the angle changes on valve job to make it a true radious? Is it worth it at all?
Eric, Can you post what the mopar head flowed stock? Also, I'm guessing the stock intake port is about 270 cc's? Looks much larger than most aftermarket mopar 440 heads. Thank you
@WeingartnerRacing Makes sense Eric, and I think you said that in your video. Sorry fir asking a dumb question. I agree, best Mopar heads I've ever seen. Nice video & great porting. Interesting port shape also. Thank you Terry
Ok one of the most powerful bbc heads is the sr20 style it has 1.80 exhaust valve and makes much more power than 1.88 exhaust conventional head. Almost every head is undervalved intake valve.
Random question. Since a kid my dad raced crate dirt late model and I’ve been around the GM Fast burn SBC Heads. They seem like a promising design but can’t find any info within the last 15 years. Anyone done a max effort fast burn headed deal? Flow/dyno #s? Just a curious cylinder head dork here.
Although superior performers,.these Brodix heads are a dedicated "Race" head. The Trickflow stuff is cool because you can retain a factory style valve train and induction system. With the Brodix heads.. all that has to change. Rockers, intake.. exhaust .. all has to change. = VERY EXPENSIVE
The koffels designed the b1 head and had indy? or brodix? cast them with rights. Theyre great people, several pro stock championships back in the day. Do yourselves a favor a search "koffels place b1 heads" stock block 400 bbm with b1 heads...
The Trickflo is a Max wedge design, and the B1 you need a different piston because of valve offset it's a great head if you want to go real fast the B1 ,
I’ve been running B-1 original heads on my Super Gas racers since 1997. First a 499, then 3 , 511’s. I was told that I would need offset bushed lifter bores to “Straighten out” the intake pushrods, which are tilted to get around the intake port. I never did that. I use T&D rockers with NO issues. I still run a 511, that I built in 2004, using a 400 block, with 440 mains and steel caps. Pistons are 650 gram, flat top Venolia’s, and Eagle BBC + .400 H Beam rods (6.535”). Engine goes over finish line at 7350 rpm. Made 890 hp, when fresh.
My dad used to run a B1 632ci in top dragster spraying nitrous in the early 2000s. We had push rod problems running it that hard to make the 16 car field.
Don’t leave out the AMC guys! There might only be a handful of us, but we’re as die hard as our Mopar Cousins.
I'm a Mopar guy... You did great! spot on with your explanations too.
Thanks Eric! Love seeing the Mopar stuff.

I had a set they worked great for the money out of the box in 97 they. Cost 1999 bucks never ported no problems at all ran em 4 ever
I ran them years ago in the late 90 1962 dodge 500 cid 200 shot of nitrous solid 8.60 stock suspension good product

The pso and the mc heads were built for big bores. The original can be used with factory block bore sizes. That head will make 1000 hp anyway.
Right
Great Job Sir,
Yup bout 1700 bucks bare and require specific pistons rocker arms valve train and what not for the heads if I remember right also.
🤪
Yeah it was $10,000 total for everything back then for complete head
You need to talk to Dave Koffel, who has been selling this head for YEARS. I think he was involved in its development.
Great video

What inline wedge head has the best modern chamber?
Eric,
Can you post what the mopar head flowed stock?
Also, I'm guessing the stock intake port is about 270 cc's? Looks much larger than most aftermarket mopar 440 heads.
Thank you
They came small for Cnc porting so I wasn’t able to flow them stock.

Funny because David Vizard (engine god) says that big block chevy is under valved..
I do not knock anything that guys says, but I would love to see flow numbers and Dyno results to confirm his statement.
Ok one of the most powerful bbc heads is the sr20 style it has 1.80 exhaust valve and makes much more power than 1.88 exhaust conventional head. Almost every head is undervalved intake valve.
You have to remember. It's much harder to move cool wet dense air than hot dry thin air.
To defend Vizard a bit he is talking about the intake valve. And spoiler he's right
The INTAKE valve can always be bigger in terms of optimal power production. But we're limited by bore size and spacing.
What if you polished the short side ? You think that would help ?
It is
I want those for my 440

How do you rate this head compared to the Trick Flow Mopar offerings?
These are superior.

There's no comparison
Its strange to see a mopar B head with a chamber that doesnt look like a horse trough.

It’s superior.
@@WeingartnerRacing also vastly superior dollar wise.

Can you stick to Chevy stuff? Now I want to build a Mopar in addition to a Clevor. Just messing with you, cool stuff.
If you cut the BBC ex valve down to 1.850 it will pick up torque. Like you said, the valve is to big
Torque AND Power.... Every time. 👍

Mopar or No Car!!!
Not a mopar part, should not be allowed to compete in a mopar class. Find your own class.
I will NEVER consider these as MOPAR heads, they don't evrn take mopar parts to complete them on an engine.
I have MP stage 6 maxies and they don't either.
What port size was this head.
Off topic question, do you prefer air or electric die grinders and who do you recommend for them and the burrs?
Electric and burrs from cylinder head supply. I do sell my used ones.
99% of Mopar guys are too cheap to buy a head like this. How do I know? I'm a Mopar guy.
Thanks for not forgetting us Mopar guys
