I received the Gen 3 Victor heads directly from Edelbrock a week or so ago after waiting for them for over 5 months due to some changes Edelbrock made to the heads.
I spoke with a engineer at Edelbrock about the changes made to the Victor heads. The engineer said the ports and combustion chambers were not changed however the following changes make these Victor heads different from the Gen two castings.

The solidification process of the heads is more controlled than the previous process. The benefits are a more consistent casting with less impurities in the aluminum.

The center rocker shaft stand on the heads is thicker by 3/16 in order to better handle the emence spring pressures seen in some full race applications.

One of the heads I received had some core shift however I'm moving forward with this set of heads. Here are the flow numbers out of the box Future posts will detail the changes made to the heads with new flow numbers

100 in 77.2 / ex 55.7
200 136.4 / 110
300 196 / 143.3
400 251 / 188.3
500 295.5 / 201.2
600 314.8 / 207.7
700. 318.4 / 209.3

All flow work performed on a SuperFlow SF-600 at Thunder Performance in Madison Heights, Mi.

Thanks for the documentation! J.Rob

When will you be posting the descriptions and flow tests for the additional work done? Those numbers are pretty sad for how that head is intended to be used.

Those heads flow very poorly as do many. I see exactly that kind of flowrate on my bench. J.Rob

Man that is PATHETIC. Who the heck do they have designing these heads. You would think that after all these years they would be able to get it so much better out of the box.

They go to the trouble of changing other things on those heads, but couldn't tweak the ports a little?

When they first came out, the Gen 1 heads would flow about 325-330 ootb. The Gen 2 was a big step backwards........and it appears that trend remains unchanged in the Gen 3.

Gen 2 head, ootb, Ede 2.20/1.81 valves, 4.375 bore, radius plate on intake, no flow tube on exhaust, #1 cyl;

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....... If those numbers werent bad enough...... I could see the way the bowls/chambers showed a little core shift....... That the numbers would likely get progressively worse as you worked your way down to the other end of the head.
Same head as above, #7 cyl:

Lift---------in/ex
.100---64.2/51.0
.200--126.1/104.1
.300--183.4/143.8
.400--238.9/167.4
.500--281.6/174.8
.550--297.4/176.0
.600--311.8/176.0
.650--302.4/176.0
.700--308.7/176.0

All that money and work to maybe match a stock Apache head.

This is our chance to let Edelbrock know what we think. This thread will be sent to them as they asked me for feedback

MY 360-1 SMALL BLOCK heads flow 343cfm at .700......

Why go big block ?

Dan

The Gen 2 heads I ported for Brad H had what I consider ridiculously small bowls.

I ended up making them about .300" larger in diameter than as cast.

IMO they should be cast with the bowls around 2.00 int/1.64 ex.

They're supposed to be race heads....... They don't need to be great for a guy running a .480" lift cam, so the bowls/ports should be configured towards high lift race applications.

My 360-2 heads flow 337 @ .650...

And those 360-1 and 360-2 posts are relevant to this thread about BB Victor heads how?

Are those Max Wedge Victors? If so, the flow numbers look pretty weak when compared to a Trick Flow head. Any chance the guy has Trick Flow numbers on the same bench? It would be nice to do a comparison if he does.

You can tell from the pics.......std port.

Sorry I tried to delete my post but it will not let me.

Std port. He does not have Trick Flow heads to flow.

Still seems a little weak for a standard port head. The Trick Flow 240 head numbers are a little better than that and I think they are less expensive but it probably depends on which parts you buy. The Trick Flow heads are fully CNC ported, not sure if the Victor heads are. From what I recall the Victor heads were only port matched but maybe they have changed that since I had my set many years ago.

Just the port entries are cnc'd on these heads. We shall see what a valve job and some port work will do to improve the numbers.

Not sure what value proposition that Edelbrock thinks they have selling a non-ported head for basically the same price as the fully ported Trick Flow heads. They call the Victor a race head but they don't give it enough installed height or good enough ports to really be a race head. The Victor heads are also heavier than they need to be because of all of the extra material on the intake face. They need to fix that design. It shouldn't take too much work, not sure why they don't do it.
