MP Super Commando Heads

-
I, for one, appreciate the blunt honesty of your posts about your experience with the heads.

What bore are you running them on?
Flow numbers on that bore?
Intake valve size they came with?
Are you using that size valve?
Do they come with 11/32 or 5/16 stem valves?
Do they use 5/16 or 3/8 rocker hold down bolts?

Never had a set in my shop, but from what I read it sounds like they are similar/the same as the Indy T/A heads.
Those use 5/16 stem valves and 3/8 rocker hold down bolts(according to the catalog).

My prediction is that the TF SB Mopar head will have a bigger impact on the SB market than the BB head had, since there are less similar options for SB’s....... and there’s a bigger gap between what they offer for the $$$ vs the competition.

I predict it won’t be long at all before someone has a set making 600hp, right ootb, on a pretty basic 408/416.
Wow. Now I'm crying even harder lol

I went and dug out my dart file from my office...

280 at 650 lift...sad...thought they did better. And that's EXCESSIVE porting. Imo. Like $1k worth at employee cost at the time at TEA.

Had 1100 in block maching... made 608 on the dyno at 7400 though.

Anyways. Valve size is as delivered but was not matched to that the instructions said. I think is stated 2.08, 1.6 and these were 2.10. And .16x forgive my memory but I remember both were wrong. Why I advised above that literature nowhere is correct on these. Large valve stem.
They did take 3/8 rocker arm bolts.

Kinda shows how much the TFS heads are going to blow the market up IMO. I wonder if TEA (TFS) used my dumper heads to learn from as they designed these lol when I was there they did have a edelbrock mopar head that was all bondo'd up, I remember talking with them about how that head was going to be huge once they got it perfected....in the next 10 years
Shows how long this stuff takes to come to market sometimes.
 
Thanks guys. Mine has 2.08 / 1.60, 11/32 valve steam. 5/16 rocker bolts and same size of intake and exhaust runners. Basically is a Edelbrock head!

I'm running currently on 360" 3.58x4.000, 11.8 CR, Pump Gas, Solid Flat Tapped Cam, Tunnel Ram and with a set of Edelbrock ported by myself that flowed 310@.650". These heads already has 2.08" intake valves and a huge work on intake runners that has 195cc with std LA port. This engine produces 484WHP@6800 and runs 6.73@103mph on a 3300lbs a-body. Can runs easily on 6.5 with a better 60ft.

I spend a lot of time just making measurements on intake runners to see if I can do a decent porting work on these heads. So far, my expectation is good based at all that I saw.

I believe that making a good job, these heads can flow over 310cfm with the benefits of a large port can provide.

I will keep everyone informed about the progress. Thanks a lot for all information.

Thats the same PN head i posted? I'll be following to see what numbers you end up getting. Thats awesome if you get into the 310 on a 4 inch bore. wow.

Is it just the way they look in this picture...... or are the port openings a little wider than a std RPM head?

Thanks Johnny, PN is almost the same. Mine is a little bit different then yours. On the front of head has the PN P5153850. This must be the PN for a assembly head and P5155128 would be a bare head.

I made some tests in my flowbench using different bore sizes to understand how the bore size really matter in the flow. I flowed Edelbrock heads, 2.02" intake vales in 3.940", 4.000" and 4.060". Difference between 3.940" and 4.060" was 2cfm. Not a big deal IMHO.

I guess i'm confused on your previous post where you noted some flow numbers. So have you bench flowed THESE heads? or your 300 CFM was in reference to actual edelbrocks?

What do these MP heads, with a 2.08 valve, flow on a 4.00 bore @600 lift? Have you flowed the yet?

Edelbrocks with a normal 2.02 wouldn't be affected much by the bore sizes i agree. From my understanding the 2.08+ on a 4.00 bore...the valve is so large that its shrouded by the small bore size, and actually kills flow because air can't move around the smaller space left between the cyl wall, and the edge of the valve. I'm not an expert by any means, so i'm not "challenging" your first hand experience. Just looking at what mine flowed on a 4.030 out of the box, and even after trickflow ported them...I honestly do not believe you can touch 300 with these on a 4.00 bore. If you can, your porting skills are phenominal. i know you don't need my gratification or approval.lol I'm just genuinely interested in the results you get, as almost noone else has these. So i now have someone else to compare to.

Sorry for confusion Johnny. I flowed 310@.650" on current head that is installed on my car this heads has 2.08" intake valves and was flowed using 4.000" bore size. I didn't flowed Super Commando yet but I will keep you informed about the number as soon as I have.

Here is a picture of my head that is currently installed in my car.

Those are gorgeous. I have no doubt that you're a skilled porter. And 100% believe you that these do 300 CFM.

I think you'll be surprised with the super commandos on the smaller bore sizes. But time will tell. thanks for the clarification. eagerly awaiting results :)

And through a 193 cc intake runner?
That is amazing.
On a Edelbrock head currently installed?
NICE!

It only picks up from here on a bigger bore.

What head is currently installed?

Yes Rob, 193cc. Flowed 303@.600" and 310@.650". Edelbrock 6077 head with 2.08" intake valves that is currently installed in my 360" engine.

The plan is replace these Edelbrocks for the Super Commando that I posted the pictures above. I would like to measure the intake runner volume tonight.
 
That’s gotta be sweet!

Best of luck on the current effort.
I’m so subscribed to this. I liked the head when it came out with the moved pushrod. Though that currently seems to be the heads bane.
 
Very cool! So what's the timetable for the bench flow on the 4.00 bore?
 
Had a buddy who ran those super commando heads in a bracket car with a stroker and 904 few years back
They had been fully ported by a reputable guy most on here would know.
Plenty of compression, roller cam, etc, etc
Never ran as good as i thought it should. Struggled to break 10 flat in a roughly 3100 pound car. Ran around 130-131 mph in good air. Usually 10.0xx something
Not that impressive for what the combo was in retrospect. Hsd a good bit of money and effort in them

Yes man. I have heard about the "Bad reputation" around these heads and that they don't give the real power that they should. I'm spending a lot of time on measurements to calculate and correct what I think that is wrong on these heads IMO. I'm doing a huge porting work to try make this heads give the real power that they should. It's been painful so far but I really like a challenge. lol

Good luck.
The set i mentioned, several people who know what they are doing worked on them.
They aren't a terrible head. But they aren't going to make power like an Indy or W5 would. More like a very good Edelbrock head.
 
I'd say 131 mph trap speed in a 3100 lb car is making decent power. ET is a lot more than the engine

Again..... not the power of a W5 or Indy head. But cost wise every bit as much. Just better options out there.
Regards the 131 mph. It was made in an extremely well sorted out car. If anything the “ car” helped the motor go 131 mph. Car was 3100 with driver.
Thats close to 600 horsepower. Not impressive for a roller cammed stroker with lots of compression and a 904 behind it.
Argue if you want. Dont care. Just think that head isnt anything i would throw money at
 
Hello Guys, sorry for delay but finally I got the heads flowed. I'm very satisfied with results.

208cc intake runner
2.53 MCA
2.08 intake valve
4 angle valve job
65cc Combustion chamber
4.000" bore measurements

Cooool! Better late than never. You can only go so fast anyway. Thanks for the update. Port pictures? Exhaust flow numbers? Thanks!
