Anyone ever run Speedmaster Heads on their small blocks

[MOPAROFFICIAL]

In the bold.... huh? Say what? Mean what?

Rod ratio

I think they got there pic mest up on the shocker sight.
If you click on the picture and then read at the bottom the closed camber said FORD and the open chamber says BB mopar.

If I were in the market..ld buy the shockers if I decided not to port the factory heads. Better head.

 

[Cudafever]

Are you saying that because of the 185cc intake chamber???

 

[Cudafever]

The SM ported head are 190cc intake runner.

Mopar Chrysler SB 318 360 190cc 68cc CNC Hydr-R Complete Aluminum Cylinder Heads

Small as necessary for the big average numbers. Besides, if something's fkd up I have a hair more room to fix it .

 

[rumblefish360]

And the SM site has no flow numbers

 

[Cudafever]

Agree.
the combustion chamber look bigger on Shocker but claims to have 65cc like the SM's How ever the ported SM" have 68cc aka the chamber needs some work!?>.!!

 

[rumblefish360]

Shockers come in 63 or 65 cc.

Someone needs to flow test the SM heads.

 

[Cudafever]

Is there flow number out there for the shocker?
Claims 285 but is there a full lift swing of the port somewheres?

 

[rumblefish360]

CNC Shocker 185
Flow Data @ 28″ water
lift 200 300 400 500 600 700
Int 142 202 251 278 284 286
Ext 124 159 190 203 219 231

Not to bad IMO. I’m sure they can be improved.

I had a guy flow a shocker a while back and they are pretty close to the advertised numbers up to 500.

I am going to try to order a set of bare heads tomorrow. If I get a set I will put a set of my Edelbrock valves in them and flow test them. I will then port one intake port and give flow numbers after several mods. Valve job, Open pinch, straighten common wall, chamber work, short side widening, etc. I will also post some air speed numbers

Pro max shocker 185cc
.200-.500 lift flow numbers are real good.

Needless to say extremely interested...

Of course PRH just posted numbers 4 unported heads on one of the other three threads that's going on these heads right now... ..

Nope...... that’s a repost, of a repost of 70aarcuda’s post of his CNC speedmasters....... after being prepped(valve job, etc).

I'm confused, maybe, but I think those #'s are for the CNC ported SM's posted by another member, I think. lol

Nice!. I was thinking of getting a bare set of non cnc heads to see what they could be become on a budget-is that what you are doing or are you getting the cnc?
