The Victor M.W. heads(3 to 5 yrs old) I have are fully ported all the way to the valves confused

Of the limited number of BB Mopar Victor heads I've seen that came ootb from Edelbrock(only like 6-8 sets), they were all "unported" heads.

On my bench a TF240 head flows a little over 320, with very good low/mid-lift numbers.
The Gen 1 Victors flowed more at high lifts, but had pretty soft low/mid-lift flow.

Hand ported, while retaining the as delivered port opening, the std port Victor can flow 350+ with decent low/mid-lift flow.

By modifying the core plugs, I don't see any reason why Edelbrock couldn't have these heads flowing 335-340 ootb unported, with significantly improved low/mid-lift numbers compared to how they come out of the box now.

The only reason they work as poorly ootb as they do now is because they aren't trying to "fix" it.

My point of view would probably be different if I owned a CNC and had a steady stream of customers sending these heads to me to have ported.
I felt like the Gen 2 version required too much porting effort(for hand porting) for that level of performance.
If you're just running it through a CNC machine, how good it is to begin with doesnt matter as much, as long as there's enough material in the head to allow you to get where you want to be.
But for the guy that likes playing with his own heads, there are other, easier options.

I'd love to hear what the Edelbrock marketing guys think the Victor head's competitive advantage is. It isn't as good of a race head as the Indy -1, it isn't cost competitive with the Trick Flow heads, it isn't a street head like the RPM.

It isn't like Edelbrock doesn't know how to build heads. They make some cools stuff for Chevy and Ford engines. They sell CNC Victor heads for other brands that are really good heads so they could make a good Mopar big block head if they wanted to.

I came up with an oil restrictor in the rocker stand using a Mig wire tip fitting and you drill,cut to length.just an fyi.

As a point of reference........ The Pro Comp version of the Victor head(which is a copy of the Gen 1 version) will flow 335-340 with a decent valve job and a "good" bowl blend.

If we're being totally fair to the std port Victor head however, it should be brought up that they do flow more ootb than another head that's been a staple of the better running std port crowd for a while now.......one of my favorites actually..... The Indy SR.
While the SR can be made to flow pretty nice numbers in both std and MW form....... The fact is they aren't very good ootb.

Perhaps a price adjustment is in the works, the TF's haven't been around that long. The -1's are a big head, too big for many combinations. Perhaps the thinking is that a 'race' head should be 'sized' by the end user for the application. Displacements and engine speeds are all over the place and there's no way to produce an ootb head that works well for all. There are already at least 3 'ED' BBM heads on the market. Now if they offered a CNC version ootb with bigger flow numbers so buyers wouldn't have to (if necessary) have them ported by a third party (or at home) it could save engine builders some valuable time. But what are the perfect flow numbers? There aren't any.

True. But these...

Lift------ in / ex
0.100 -- 75.0 / 55.0
0.200 - 151.3 / 116.2
0.300 - 220.1 / 154.9
0.400 - 280.3 / 194.0
0.500 - 326.1 / 223.3
0.550 - 338.2 / 233.3
0.600 - 346.0 / 241.3
0.650 - 350.5 / 247.2
0.700 - 355.5 / 251.8

... sure beat the He11 outta these...

Lift---- in / ex
.100---71.9 / 52.7
.200--135.9 / 99.7
.300--196.4 / 143.8
.400--249.4 / 174.8
.500--292.9 / 187.7
.550--309.9 / 189.0
.600--296.7 / 191.0
.650--304.2 / 191.7
.700--317.5 / 192.9

... and retain a standard port entry, too.

Even if they couldn't exactly duplicate this ported form short of a CNC program, they surely could recast the ports to be far closer to the first set of #s than the second.

Did they correct the push rod pinch issues in the latest heads?

Still under 300cc as well.

I'm sure they could be made to flow 335-340 and only gain a few cc's over the advertised runner volume of 280cc.

I never cc'd one of Brads intake ports before I started whittling on them, but since the bowls were much smaller than the Gen 1 heads, I would have been pretty surprised if they were actually as big as 280cc.

Maybe ccdave will check one of these new ones before any work is done on it.

Have you considered opening them up to MW size Dave?

So, if we arbitrarily say 2hp per cfm the first head would easily go 700hp while the second would only go 600hp. BUT, the second head could be ported to match the first while the first can't be downsized for a milder application (without a lot of welding). I have no problem with them coming out with another head casting. I suspect that Edelbrock thinks we only build 440's and that's what they target.

I think it's a pretty safe bet that if someone is stepping up to the Victor style heads they're trying to make some power.
In which case, I can't think of any type of "normal" build where the barely over 300cfm version(with the accompanying quite poor low/mid-lift flow) would be the "better" option over the 355cfm version.

If you thought the build was better suited towards a smaller head...... The TF240 fits that bill, or a ported RPM head.

If you have a set of dividers or a snap gauge, I'd be curious to hear what the bowl diameters are, at a height about even with the end of the guide.

277cc's is what I measured.

Do you have a way to measure the bowl diameters?
