one of the things the guy was bummed about though, seemed to be he felt the torque was soft in the lower rpm's. i think he was hoping to get to ~575hp and also pick up the torque curve a little too.


The low end TQ was pretty poor.
I don't think I can point the finger at the SV intake alone for that.
As I said, the bracket 416 I did a few years ago had that same intake on it with only a quicky port match....... And that motor was up 100ft/lbs at 4000rpm.
Peak TQ to peak TQ the motor I did was only up about 10, but the bottom of the curve was much better.

What can you really tell from pictures of ports? But, looking at the BPE head's pedigree and pictures, it seem hard to believe that the lack of power lay in the heads.

We just pulled our BPE 4.125 stroker kit 424/360 off our dyno here in Idaho a few days before the engine with the BPE heads was tested across the country. Ours was running our Indy LAX iron heads (290cfm @ .500", 301cfm @ .550", 303cfm @ 600", 297cfm @ .650"), Chevy 1.5 7/16" stud mounted rockers, Super Victor intake, 950cfm 4150, solid roller 258/260 @ .050, .425/.430 lobe lift, 10.83:1 compression, 165 psi cylinder pressure @ 5,000' elevation, 91 octane pump gas. Best pulls....480 LB-FT @ 3,000 rpm, 572 LB-FT @ 4,800 rpm and 603 HP @ 6,300 rpm.

How could a well set up stroker with the BPE heads not be capable of at least the same results?

Someone is surely wondering about the flow bench accuracy. As a comparison, the very best intake flows I've gotten from the OOTB Edelbrock RPM small block head was 248cfm @ .500" and 250cfm @ .600"

And the dyno? I always wondered. I took a mild big block stroker that was making 598 lb-ft & 585 hp on our dyno, to another dyno the very next day. 150 miles away and 200' elevation lower, with no changes to the engine, it made 615 lb-ft & 600 hp.

You cannot race flow benches or dynos.

I'm telling ya......If I was in the market for set of small block heads, I do believe I would still try the BPE heads.

A few more ramblings.......

Looking at Jim's 424 combo above, the "other" motor wasnt really all that far off as far as peak hp goes, if you look at the hp/ci.
Using Jim's 603hp and 424ci, it's 1.422 hp/ci.
If that 410 made the same per ci it would have been 583hp.
Since they saw 567 out of it with a carb spacer, that's 1.382 hp/ci......so, not "way off"(16hp).

My gut feeling is, whatever is making it so the low end TQ is so far below where it really should be...... You fix that..... It would put up a better number up top.
I see it pretty often........ Start low/end low.

Hi guys! Well, I joined to add to this that I am the guy who started the very long post on the A body forum. I am the first person to ever buy, install, and run the BPE heads on the dyno.

So to clarify things, the BPE heads were run with EXACTLY the same combo as the Hughes Eddy's(560 HP@ 6600(I believe), 439 ft/lb @ 4000).
The only change was the rockers were verified as ALL having a true 1.6 ratio.

I thought this Edelbrock/Hughes combo had a poor low end and honestly felt the HP should have been better.

Hence the chance on BPE heads.
They did look really nice. The intake port opening seemed really big, to me. Had to open up my Super Victor quite a bit more than with the Eddy's.

BPE heads bolted on and to the dyno. First thing we did after warm up was to adjust valves to .020/.022 per Tim at Bullet.

After much trial and this and that the Bloomer heads made only 534 HP at 6300 and torque was pathetic at 391 at 4000 RPM. This was our best pull.

I spoke to Rod who seemed as devastated as me and eventually he had me ship them directly to Brett Miller. He said he would send me a refund along with shipping. Brett got the heads Tuesday. I have heard nothing and got no check yet, but I believe Rod was sincere. He has stopped his head program until they can figure out what the heck is wrong.

I blame myself for being the guinea pig AND I sorta blame Rod for selling an untested product. A very expensive one at that.

My dyno guy has his thoughts as to the problem, but I'm sure they will figure it out.

Rod has been nothing more than sincere and said from the start he will make it right.

I have no check in my hand. Yet.

So right now I have a real nice bottom end, sitting with no idea where or who I can get a pair of heads from.

I'm sure Brett will get those heads figured out he is one of the best out there on small block mopar heads that's why the victor heads had so many delays they would not make the power edelbrock wanted power Brett differently knows how to make big power I would wait and give the heads another try and if they make the power your looking for then pay for the heads

Thanks for the clarification, and welcome to the board.

I'm sure "the check is in the mail", and once you have it you'll be able to figure out what your next move is.

Sure would have loved some cranking pressure numbers though wink

Yeah, me too. Something crazy starts happening and I sort of lost focus, worried about other stuff. I have to figure cranking psi was somewhere in the 185 to 195 range.

I run a vey similar Lunati grind that's 188 PSI.

I find it weird that Rod didn't call to say "we got them" or SOMETHING. This might not be over yet. Hope I'm wrong.

Dyno numbers.

I have the heads been on the flow bench.

Nothing I see wrong with heads. (Like to change valve job just to see)

I have not said much about this deal but let's get the facts out

Rods chambers 4 cc larger than other heads almost .5 point of CR

Valve lash was not the same for both heads on the dyno print outs that I have seen.

You opened up the end of the intake (big mistake IMHO)
This changed the taper of intake.

Why 6° timing difference in the Engine's?
Chambers are about the same plug locations the same.

This engine should have been run on pump gas no race fuel mix

I believe loss of compression plus race fuel mix and wrong cam IMO contributed to the increase of timing

Both heads run on pump and race gas mix. Best pull posted
Valve lash was changed on both. Numbers were best pull for each head.
Same for timing. Best pull posted.
.4 points in compression ain't that much on this type engine. So I'm told.

So you're saying that the intake port could be .200 smaller than the head port?

I haven't bad mouthed ANYONE but maybe Hughes in this whole ordeal. Their heads I DID have flowed. I didn't have the BPE heads flowed as I felt I didn't need to.

All that being said, since I don't know much about heads my dyno guy told me this: The venturi is blown out, the approach is all wrong and the ports are way too big. Not to mention the 2.08 intake on these heads is badly shrouded on a 4.040 bore. Not so for the same valve in the Edelbrocks. Somehow, someway the valves are closer together in the Eddy's. I had to re shim my rockers to make up the diff.

He said velocity was probably all wrong causing big time turbulence, and something about "going sonic".

My dyno guy is a proven, well known racer in this part of the woods. I always believe what he tells me because he has proven it so many times.

I did everything a guy could and the heads did not perform as advertised....yet. I'm sure they will get it figured out but right now, they are not ready to sell. I mean come on. Those torque numbers are pathetic.

I don't really want to say anymore at this time. I just want a pair of heads that are ready to make some power.

Well dyno sheet clearly marked pump gas race gas mix.

Yea torque is pathetic but not the heads fault.

Min cross section 2.1" air speed down center of port at .600" lift 310 FPS
Short turn 380- 420 FPS (little fast)


Yea and end of intake can be way smaller than head and still run good or better than blowing the end of it out.

Never said you bad mouthed anyone but you sure don't like to put all the facts out.

But in the end don't matter to me.

All the facts are over there on the A body forum. A friend told me I better check it out here.

I'm sorry but I know those heads aren't ready yet. I have the same engine combo(almost) in the car now, making 540 HP and gobs of torque. With ported iron heads and a little less cam. Almost IDENTICAL combo. I've done quite a few Super Victors now. I always match the top and sides, leave about .030 high on the bottom. All have run great.

I wish to God these heads would have worked out for me. You have no idea what I've gone through.

Do you think if you had bolted the Hughes heads onto the iron headed motor that the result would have been a big reduction in low end TQ, and only a 20hp gain?

I thought I would just address a few things to hopefully put all of this into better perspective. First of all, though these heads are very high quality and I know they have the potential to be a real asset to all of us small block Mopar guys, I want to be clear that, in their current state, they did not perform as I expected in this particular application. We have already started looking at possible ways to modify the current program/valve job. It is my goal to offer cylinder heads that exceed expectations and I will do what it takes to achieve that.

With that being said, I do want to touch on a few things that have been said in this and another forum. First of all, I did have multiple conversations with Mike before selling him these heads. He was aware of the issue I had with the dyno while testing and I made it very clear several times that I could not promise that these would make the hp & torque he was after. I did tell him he could flow them, check them out as much as he wanted, show them to his engine builder, etc, and if he did not feel comfortable with using them for any reason, I would take them back and refund his money in full. However, if he bolted them on, they were his. I was trying to be as fair as possible. He decided to purchase a set and then asked me to take a personal check and ship them before it cleared. That is obviously not a wise business decision and not something I normally do but in good faith, I took him at his word and shipped the heads before the check cleared. I do feel somewhat like my character is being questioned because he now has to wait a few days for my check to reach him. I assumed that the "good faith" would work both ways. Brett received the returned heads on Tuesday, May 9th at his work place. He brought them home that night, checked them over for damage, and let me know they were good. I wrote a check and sent it out the next morning, Wednesday, May 10th. I not only covered the cost of the heads, but shipping both ways (and now shipping to send his spring locators back to him as they were left on the heads). I do not know what more I can do to make this right. I believe I have gone above and beyond to do so. Did he ask Hughes for his money back after their heads did not perform to his standards? No he did not because everyone knows, this is not a common practice in our industry (and he would not have received any money back).

I do want to thank Brett for working with me and everything that he has done to help me reach my goals. I do not want this to be any kind of a bad reflection on him. I take full responsibility for this. These are my heads, and my business. So no excuses, I am moving forward and you can expect that when these are fine tuned, I will have a better overall product and will learn from this. "If you think you know everything, you'll never learn anything".

One last thing is that I'd like to thank everyone that has called, texted, emailed, and given me words of encouragement and support. It is VERY much appreciated! You are the reason I continue to do this.

Rod
