Some B1 Original pics.....**UPDATED** AGAIN**

Those heads belong to Mark Weaver. We are both pretty anxious to see the step by step improvements made throughout the porting/machining process. They will compliment the World Wedge block and CP pistons nicely along with a custom spec'd IMM solid roller cam. I just wish someone made a cast tunnel ram for those heads. That would be great. A custom fabbed sheat metal manifold would be cool, but at $3500...its out of the question/budget. I didnt realize that there wasnt a market for a cast tunnel ram for B1 heads. Bummer. B1s just seem so popular for people that want big power.

could an Indy tunnel ram for 440-1 heads be made to fit??

---

I will check it out soon. I have a Tunnel Ram for Indy 572-13 heads that I will try out.

DV8, Yes he is going to put it into the Valiant,... the second Valiant that he purchased. Mark bought a Valiant from another board member here and it was a MAJOR pile of junk. The second Valiant that he bought is REAL nice. It was a former True 10.5 car that was from the northwest. The car is gonna be real sweet with the new B1 in it.

---

Cool! I remember my cousin saying that first one was junk when he saw it(I have his old '66 Satellite).
Tell Mark I said "HI" & Good Luck!

Hey Steve how you doin? The first Valiant was a mess. I got a great deal on the one I have now. I got it from a guy in Washington. Night and day difference between the two. Hope all is well!

---

Good.

Upgrading the '66. Going to overhaul/replace a LOT of stuff. Thinking about selling a kidney or becoming a pimp...

Fortunately I was the only one who got scammed. I ended up selling the Valiant for what it was really worth to a father/son in Arizona. They were pleased and I was out a lot of $$. Let the buyer beware!!

The first Valiant is the silver/gray one you're referring to. The seller misrepresented the car. I took his word for it like a dummy and I bought it sight unseen. It's really my own fault. I lost about $5,000 on the deal once all was said and done. Lesson learned!

Steve, just to remind you that JESUS RULES!!!

...ok. I could use his help now. I hope that wasn't your last trinket...

Hey Brian is there a speed you like to see at the different CFM levels and is that speed linear. Nice work.

It all depends on application. If your trying to speed the air up to compensate for something, like low compression then you do what you can to speed it up. I like to make the port as fast as possible, then slowly work on controling the air speed at the lifts that are important for the build.
This build, being a 540 peaking at 7000rpm, will need the air slowed alot more, and will need more cross section. But I wanted to show people that these heads that everyone says are slow and lazy are not...unless they are ported to be slow and lazy. Every person I've talked to about B1's has the notion that they need to be fully ported and have at least 500cid to use them....NONSENSE!
Infact, these heads can be used in quite a wide area from pump gas low compression engines, to smallish engines like 440's and also work good on 540's and up.
I just wanted people to see them up close, and personal and see what happens if you know how to make them work.
I'll post more pics and info after they are done for this project, so you can see the different stages.
Alot of guys chase that almighty flow # with these heads, and I'll bet the majority of these B1's floating around out there are over ported and under achievers. I'm not trying to start a wrestling match with anyone, so don't go there...I'm not claiming to be the guru of B1's, just trying to prove my point that these heads don't need a ton of work to make them perform.
Plus I think there are alot of tall tales and bad rumors about B1's and how they are very involved and super expensive. Well, they aren't cheap, but they will make more HP than 90% of the BB mopar heads out there so...you get what you pay for. Damn, I'm not even a dealer for B1's...
I will also show the steps needed to make these heads work, like the oil drains and pushrod clearancing that anyone with a die grinder and a bit can do.
Unless your name is Rob... No grinder for you Rob

Great post to this point. Nice to see someone showing the potential of these heads and also debunking some of the old wives tales. Not to mention you have only scratched the surface of the potential they have

---

You are backing up with hard data what i have been preaching for years...lol Nice work, too.

Hey Al, you said you would run a B1 again in the Cuda..dont you mean B1/ TS heads...

Ha Ha HA MOFO!

Nice work. Definitely a step or maybe a staircase above the "monkey with a die grinder" porting!

Quick question: How come there's no talk or much use of the B1 MC's anymore? Do they still make them?

thanks,
Steve

---

The reason we didn't run the MC's, is because the intake valves need to be Ti. That drove up the price considerably. All Mark really wants is at least 800HP! I think he's going to be happy for sure
Yes they are still being made, and they can make a fair amount more HP than the Original on a large CID engine.

Threads like this one is the meat and potatoes of Moparts...

And, unfortunately, the stuff that used to be posted more often by some of our now-absent members.

True, but at least we are fortunate to have some that still "carry the torch" here.


Brian, thanks, I never knew you HAD to run Ti valves with the MC's, they do seem to kick it up a notch though...

Thats why I did'nt get them, too. The Ti valves added about $800. to the cost. With a 4.5 bore, i could have used them, but, like you i was'nt looking for max HP either.

Again, great info, thanks!

Quote:

---

what were the valve sizes in this head build ? and anyone have a flow sheet on a ported set...

---

Quote:

---

Brian, in your opinion, how much would your basic stock rocker arm head pick up if you unshrouded the valves to use the head on a 4.5 bore?

i cant get over what the chambers look like on that head. never seen this post before

---

Quote:

---

A flow bench is just a tool,unless everbody has there heads flowed on the same bench by the same guy there will different numbers. We have seen flow sheets that came with fully ported B-1 heads,reworked buy another B-1 shop with a flow sheet with higher numbers and we flow tested them and get lower numbers. The dyno and ET slip will answer whos are better.

500 dynoed 845hp just wondered.

It''s a 14.1 with 4.375 bore, 4.150 stroke, 0 deck, 62cc chambers, coated exhaust ports and valves. 1050 carb with throttle
stop under it. Inake has been port matched only. 2308 bobweight. Cam installed at 109

Headers are 2 1/8 by 30 with 4" collector 12" long. Heads are fully ported, I was talking about the intake being matched to
the heads. Springs are 310 seat 762 open. The jets were 92s timing 36. I wasn't there when it was dynoed but my
friend said no changes were tried. It even has a belt drive.

I thought I would give one of Brian's posts about B1 heads a bump since several members are going with B1 heads over the Winter. I think Brian did a great job answering lots of questions with some nice pictures. I know when the Daytona hits the track again the 440-1's will be sitting on the shelf and the B1's will be put to use. Thanks Brian and I wish there were more posts like this again on Mopart's but I guess those days are long gone.

---

Couldnt agree more.
Tell us about your Combo again John or past B1 engines...
My engine is similar to SuperComp's. 499 Low deck, 14:1 compression, cam is a UltraDyne R8 311...
Couldnt find it on Bullets web site, but has 278° @ 50 and .4544 lobe lift, rockers are 1.75 T&D's so lift is .795 before lash or gross lift.
Not sure on a converter but I would think a 8" 6K would be close. Headers are also Stahl's with 2 1/8 tubes and a 32"-34" length, they are near equal length.
B1 cast single 4 with a 1050 dominator.
Hoping to get this yellow submarine into the 8's. its no heavy weight Id say 2700-2750 lbs with driver.... and 800 HP should Get 'R' Done..

Should be able to hit 8.60s with good air at 2750, and a well built 499/B1. 8.80s, piece of cake.

This was a great thread. I wish someone had one like this for B1 PSO's or Predators. Oh well.....

---

Predator coming soon!

You stuff flies Al, I would agree the B-1 stuff is stought. Heck my 498" B1-BS makes just under 900HP.

Best Machine and Muscle Motors have done PSO deals and that stuff is real good.

For the money B-1's are hard to beat.

---

How fast and at what weight does that 900HP b1-BS run or is this another FANTASY dyno post?

Scott Brown, I think he uses Modern.

how much did the cnc porting cost you

At the time I had my B1 M/Cs done we had a group thing
going and it was $750 or $800... done at Modern
