This most recent episode is awesome. It puts to rest much of the speculation surrounding which ootb aftermarket head is the best "bang for the buck" for B/RB series big blocks. They compared a set of 906's with a fresh valve job to the 440 source stealths, vs Eddie RPM'S vs Trick Flow 240's. It pretty much boiled down to what everyone suspected all along.. you get what you pay for. Still cool to see some actual dyno testing on the topic specifically. Pretty much illustrated that as you progress on an average "street" big block you can expect to pick up 20 hp from the 906's to Stealths, an additional 20 hp from the Stealths to the Eddies and close to 25 hp from the Eddies to the 240's. All peak HP numbers of course. Check it out if you get a chance.

Looks like you have to subscribe to Motortrend to watch Engine Masters.

In theory, there is no difference between theory and practice. In practice, there is.

Yeah, you have to subscribe. Engine Masters is worth the price of admission alone imho.
They were running a (small "ish") hydraulic roller.. 236/241@ .050 540ish lift. Freiburger wanted it to have more cam
but they didn't upgrage it ?

906's = 514 tq @3700 464 hp @5600
Stealths = 519 tq @3600 481 hp @5600
Eddies = 534 tq @4000 498 hp @5500
TF 240's = 538 tq @4200 522 hp @5600

Was the test engine a 440?

Yes, a .030 over 440 with TRW pistons. 850 Holley XP , Street Dominator intake, 2" - 2 1/8 " TTI stepped headers. All Aluminum headed combos ran best with between 34 - 36 degrees total timing.

I think it would be a better test at 500”, with a combo where the TF heads were making well over 600hp.

Something that can really illustrate how much power the milder heads are leaving on the table.

Was there any attempt to equalize the CR between the various heads?

Or was the CR difference part of the power difference?

They stated the combustion chamber and runner volume for each after market head. Also spoke to the fact the changes in CR. Most of the comparisons were the difference in power to what it cost. Basically each time you stepped up in power you spent the extra money to get it.
Conclusion (for me) was the 440 Source was a good buy as a replacement for a stock 906 head and with paint would fool most in appearance. Each head seemed to mirror the one before in the gains of TQ and HP. Pretty informative.

The TF heads had been CnC ported. I would have liked to see a set of comparable Indy's. But they didn't get a set. Also, as tested the Indy head would have cost at least 600.00 more at a minimum.

Headers seem large for the combo but still a nice comparison.

It all depends I guess. I like that they tested a stock stroke engine with a street size cam. Both the test you suggested and the one they did can provide good info.

I don't think you could do the test with a set of "comparable" Indy heads since the TF heads were CNC ported. The most comparable Indy head would be the basic EZ head. When you get CNC port EZ heads they have MW ports so they couldn't use the same intake. I would like to see my EZ heads in that test because they are ported but still have standard port windows. work

True.. but it's also cool that if you wanna plunk down the cash for the 240's, you can pick up 25 ft lbs and 60 hp on a basic street combo!!

If the guys on Engine Masters really knew what they were doing they could make the TF head look even better.

Personnally, I like the test. I don't need another test to prove the TF is better than a Stealth on a 600 hp motor.

If anything, I'd like to see the test done on even a milder std stroke 440. There is this belief that the TF is "too much" head for a mild street 440. I don't believe it.

As much as I like the Engine Master test, I also know to not hang-on too tight to any one test

Definitely like my old 446ci 6pk bottom end motor with 260cfm? BV template ported 906's nothing special, 2.1/8" f/wells, Team G and an 850DP, plus a .650/290@.050 Mcandless sft cam, (ok so not a street cam), made 531fwhp@under 10:1CR, weight/mph calc.

We get a dyno test tailor made for us using stuff they had laying around like that short block and probably those headers and people show up to [censored] and talk how much better they could do. Why ever even bother to throw candy to this crowd?

The goal here was to bolt on the different offerings out of the box and show how they perform.

No doubt they all could have had better numbers if each combo was optimized.

Hopefully they can show us some tweaking with each combo on later episodes but I'm just grateful to get some Mopar content here of late what with this episode and the oil pump episode.
