Hi, I could use some advice. I am building a low deck 511 (street/strip car) and was planning on using the TF 270's. Now I have been offered a really good deal on some used MW Victors. I know the Victors require some different rocker arms and headers but I need to get all that anyway. The Victors have been gasket matched and port blended, no other port work. If I go with the Victors I will save myself about $1500. What do you think?

Thanks,

Steve

Do the Victors come with the springs you need to work with your cam?
Will those used heads require a trip to the machine shop prior to installation?

With only that minimal amount of work, if the Victors have the newer style chambers, they will be way down on flow compared to the TF270’s, especially in the low and mid-lifts.

Depending on what you do for rockers, there could be a few hundred $$$$ difference between the two.

I’d look into exactly what the header fitment situation is between the two so you really know what you’re getting into.

I think you need to talk to CCDave--he has all of the facts, I am missing them. J.Rob

You’re saying you can buy the Victors for about $1000.

Be very careful on your decision making when it comes to buying used race parts
I have used a bunch of different heads on my race cars over the years from stock iron 516 on street motors to NHRA legal stock 1963 M.W. heads on my old NHRA A/SA Plymouth Belvedere to Indy 440-1 on bracket motors.
My current bracket S/P car has a set of used Victor M.W. heads on my 505 C.I. 400 block, I raced that motor with a set of Eddy RPM heads that I had MCH CNC port them and then switch the M.W. Victors that winter, mine where M.W. ported all the way to the seats, not like Edlebrock said they sold them out of the box originally I wouldn't buy another set of them regardless of price
Buy the good ones once, don't repeat my mistakes on trying to save money by buying and using used race parts , especially heads

I think you will end up with the same money and less headaches in the end if you go the TF 270 route. How much power does it need to make and on what type of fuel?

So what are you saying Cab? Did the car slow down with the RPM's or what? How did the MW Victors perform? J.Rob

Junk is junk....

Hi Dwayne, I did buy the cam for this project from you (you spec'd it for the TF 270 heads). I was maybe going to give you a call sometime this week for your advice.

I know I will need new springs so I figured about $500 for the springs and machine shop install. These heads have recently been to my machinist for valve work so I'm pretty sure they are good to go except for springs.

I'm planning to use the Hughes offset rockers (part of the deal) and the $900 TTI headers setup for the Victor heads. All this figured in I'm still saving about $1500.

I'm not sure which version of the head they are. I'll need to look into that. I'm not to excited about the low/mid-lift flow especially on the street. I'd like to save some money but if the difference is significant I will stick with the TF 270s.

Thanks,

Steve

The Victor M.W. heads didn't pick this car up as much as the Duster did when I switched from the same set of Eddy RPM to the Indy non ported SR M.W. heads on the same motor that flowed 20 CFM more than the RPM did The Victors had smaller CC on the heads also so it should have pick that motor up even more with the compression ratio increase
Those Victor M.W. heads have not impress me yet
I'll be trying a new set of the Trick Flow 270 soon, after I use up the current stock of heads I have on hand

No not exactly, I get the Victor heads (springs for solid flat, I have solid roller), rockers arms, an e85 Dominator Carb and Indy intake for $2200.

If you get a pic of the chambers and post it, I can tell you which version they are.
However, without some reworking, the low/mid lift flow on the first version wasn’t great, and it pretty much just plain sucked on the second.

IMO, some of the $1500 in savings should be spent in improving the flow a bit, if you went the Victor route.

The overall fit and finish of the TF heads are just “nicer”.
Pretty hard to find a good argument against them.

I'm hoping for 650 to 700 HP. This is a street/strip car so I will be using pump gas (92/93 octane).

At over 500 cubes, that shouldn’t be too hard really.

As a counterpoint to Cabs story, Todd at Comp Wedge pulled some pretty nicely ported RPM heads(over 300cfm) off of (what I believe was) a 493 with a smallish race roller cam that was in a very well sorted out bracket car(multi time track champion), and replaced them with some Hughes CNC ported MW Victors and the car picked up about 4 tenths as I recall(something like 9.90’s to 9.50’s).

One of the few dyno results I’ve seen from the MW Victors were from Brian at IMM.
As I recall the numbers were pretty good.

Here is a picture

Here is everything minus the rocker arms for $2200.

I have the cnc MW victor on a 511 with 11.25 compression. Havent been to the track yet, but not real impressed at this point. I paid $1100 for HS rockers which isnt to far from T&D prices.

What was your combo before? J.Rob

I had an Indy headed 408 on pump gas that ran 10.30's with 3300# race weight.
