[quote=ccdaveYour trying to say that Victor heads are very bad. This is old news. Everyone already knows this who cares. Next.

Well I didn't know this way back when and I wish there were HONEST threads LIKE THIS about them so I would have prevented myself some time/$$$$.

Actually now that I think about it I guess I wouldn't have learned nearly as much because you don't really learn from your successes.

I'm calling you out, because it's a fact that not everyone knows about the victors.

There have been quite a few posts highlighting Eldebrock Victor issues and the respective solutions.

Like anything else, it all depends on what you are trying to accomplish. From what we have seen I think we can all agree that OOTB TrickFlow is the best thing going right now and they have everything covered from the RPM's to the Indy EZ line up.

That said my second 511" low deck is getting a set of 440 -1's with a paired rocker setup. Simple and proven.

So your telling me that you being the engine master, the master of all things Mopar, the king of telling people how it should have been done just found out by viewing this thread that the Victor heads have some design flaws??

Time for some ice fishing and some pond hockey. Take a break

Actually ccdave, you should probably take some of your own advice.

Danny,

Not good on skates and the ice is not out on the lakes here in Michigan. I do enjoy Ice fishing however. Thanks for your input

This is an older post that is should be relevant to the question above, if the OP is asking about standard-port Victors.

I think JohnRR's Chapman VI's also went right at 350 peak too and with better .200-.600's (from Fast's bench) than any other standard ports I can remember. I think below .350 or so they were even better than my MW 285's. Wish I'd have known when he was selling those...and those numbers were more than 12 years ago. I was thinking at the time....300 cfm at only .450 lift is pretty amazing if you think about it, even a stock replacement Mr sixpack cam in a 10:1 440 would make some serious power and have 14" at idle and a still streetable .557 or .590 purple shaft in a hot 470 would be killer with those .500-.600 numbers.

from the Tech archives:


Chapman CNC'd MP Stage VI 260cc's:

Lift" I/E

.100--71.5/58.2
.200-150.0/118.6
.300-219.4/180.0
.400-278.7/219.4
.500-323.6/233.9

.750-348.5/251.5
.800-348.5/253.1

Remember Dave, if no one agrees w/you, you are WRONG and sent to your room w/out dinner........lmao......Or, they will pm each other about you like in high school........... I'm never right so we're good to go here............

I'm sorry... can't help it... must... post... more... cylinder... head... data...

------------------------------------------------------

MP (Mopar Performance) Stage VI heads vs Edelbrock Victors (both prepped & ported significantly from "as cast"):

-------------------- MP --- EV
Intake valve ------ 2.14 - 2.20
Exhaust valve ----- 1.81 - 1.81
Intake runner cc -- 245* - 294
Intake Avg CSA ---- 2.39 - 2.76
Intake Min CSA ---- ~2.2 - 2.66

* Includes volume from intake spacers required to use on RB block (440)

III. Flow data from same Saenz 600-class bench tested on 4.375" fixture:

INTAKE - MP --- EV --- Delta
0.100 -- 69 --- 75 ---- 6
0.200 -- 143 -- 151 --- 8
0.300 -- 213 -- 220 --- 7
0.400 -- 262 -- 280 --- 18
0.500 -- 293 -- 326 --- 33
0.550 -- 305 -- 338 --- 33
0.600 -- 307 -- 346 --- 39
0.650 -- 307 -- 350 --- 43
0.700 -- 307 -- 355 --- 48
0.750 -- N/A -- 347**

EXHAUST - MP -- EV --- Delta -- EV w/ 2" pipe added
0.100 -- 52 --- 55 --- 2
0.200 -- 108 -- 116 -- 8
0.300 -- 146 -- 155 -- 9
0.400 -- 181 -- 194 -- 13
0.500 -- 211 -- 223 -- 12 ----- 238
0.550 -- 222 -- 233 -- 11 ----- 249
0.600 -- 231 -- 241 -- 10 ----- 259
0.650 -- 237 -- 247 -- 10 ----- 267
0.700 -- 243 -- 252 -- 9 ------ 274
0.750 -- 255 -- N/A ---N/A ---- 278

** Drop-off above .700" is suspected of being due to the chambers' CNC work laying back the plug-side wall too much. The same drop-off resulted when tested at 15" / 28" / 35" H20, yet without any change to relative flow #s for each depression level. A hand-ported casting that was used as a flow bench "guinea pig" didn't have the chamber pulled back as much as the CNC'd chamber program, and it did NOT have the same issue w/ dropping off at .700".

------------------------------------------------------

I don't have any buddies here but I do get tired of assholes egos running contributing members off.

Yes, me too. I’m glade we agree on something

they "copy" iron heads to cast them in aluminum,
they copy rpm heads, they copy Victor heads,
why the hell is nobody copying these Chapman heads????

or the Brewer heads!

Because there wouldn't be enough market for them to cover the costs

These arent from Brads stage 6's, but a set of the same vintage....... ootb with Ferrea 2.14/1.81 valves:

Lift--------in/ex
.100---67.4/52.3
.200--126.3/108.5
.300--181.3/137.7
.400--215.0/144.8
.500--235.0/149.1
.550--236.9/149.1
.600--238.8/149.1
.650--240.8/149.1
.700--242.7/149.1

Ootb second gen Victor(the ones with the bowls cast .300 too small, like what Brads were):

Lift-------in/ex
.100---64.2/51.0
.200--126.1/104.1
.300--183.4/143.8
.400--238.8/174.8
.500--281.6/176.0
.550--297.4/176.0
.600--311.8/176.0
.650--302.4/176.0
.700--308.7/176.0

Just some numbers to give you an idea of the starting point for using either of those heads.

And for something else to compare to.....
Ootb Indy SR std port:

Lift--------in/ex
.100---69.0/54.1
.200--132.9/99.2
.300--189.5/135.1
.400--236.2/165.4
.500--264.6/188.9
.550--272.9/196.7
.600--279.7/203.2
.650--284.2/208.1
.700--287.2/212.0

Pro Comp "Victor", std port, valve job and back cut valve, no porting(intake test only):

Lift-----in
.100---71.9
.200--147.6
.300--204.2
.400--255.1
.500--289.1
.550--295.5
.600--304.2
.650--309.9
.700--309.9

I've often wondered that myself. It seems the folks at ProComp and other such places aren't smart enough to design their own heads so they copy existing heads. Okay, I get the fact that they aren't smart enough to design new stuff but why don't they copy the good stuff?

Even if they aren't smart enough know good from bad aren't they smart enough to hire someone to help them? If they are too dumb to hire someone to help them then how do they stay in business at all? Just one of the mysteries of life...........

So r u referring to me...........

These guys are looking at what moves off the shelf fast
(not what is good).. they are selling mass (or trying)

EDIT
there is probably no more than about 5 or 6 people that
even work there and I doubt they have any design engineers
working there
