Never seen a W5 head go remotely close to 355. For one thing, they flat aren’t big enough.
I can say this for sure, even a good W5 head is more than used up with a serious effort 4 inch crank deal. You need go no longer stroke on anything like that. Those heads were designed for stock stroke 340-360 mills. Not 400+ inch stuff.

I’ve seen someone’s report on them go a bit past 330, IIRC.
Shady Dell? I forget. The W2 if carved to the high heavens will get crazy numbers. IIRC, Dick Landy carved ridiculously huge rectangle ports. It’s porting way beyond normal.

I've been very pleased with my 4.125" stroke deal. It made peak power at 6750, I normally don't turn it over 7k and it pulls like a freight train..........everywhere!

From a been there and still doing it guy. Thanks for that reply.

They will go that high. I was at 340 on mine, but it took a **** ton of work.

I think (THINK) I could get close to 400 out of them, but by the time you did all the work you might as well try and find some W7’s because that’s what you’d have.

IDK about 400, thinking of what Landy did back in the day with those monster rectangle/square ports. But for all sanity purposes, by the time you carve away what’s needed for that kind of flow, I would not expect much life from the cylinder head or reliability.

I was hoping for a little better out of W5’s myself but it gave up the ghost on that in one port. Not that it isn’t flow well as it is now. But more the merry and the planned 434+ mill can use everything it can on a cylinder head.

I agree stepping up would be it. W7-8-9…..

@justinp61 arent you running a set of Indy heads on your mill?

If you want to get near 400 you have to break out the welder because that’s what it takes.

That’s what I’m thinking. A bit of work 99.9% here aren’t going to do. Like you said, just step up on the head. Go to the Indy, Victor or higher W series.

Of course if someone just simply wanted to experiment and try it, far be it from me to say don’t do it.

Yes, 360-1's.

LOL…IF i was younger and I found a nice pair of unmolested castings I’d give it a whirl.

I‘m WAAAAAAAAAAAAAY past that now.

my W5’s were the first set Ryan( Shady Dell) ever did.
Brett actually, from what I understand, did part of them and Ryan copied the rest.
kinda interesting, those heads ultimately ended up on a very reputable bench( Best Machine) later on, and another set, done the same way, ended up on another reputable bench. Very well known guy
on both those benches, both sets struggled to get over 300.
that said, mine ultimately ended up going right at 140 mph in East coast mineshaft air, at 3220.
that is a VERY honest 700 horse.
Moral to the story, flow numbers definitely aren’t everything….at all

edit, those W5’s were opened up such that a few of the spring cups were so thin Chuck at Best Machine was able to poke holes with a pencil.
thankfully, that got caught… running a 700 lift roller at 250/600 it wouldn’t have lived but a minute or two..lol

Thanks. And yes that’s 100% true. Numbers aren’t everything. And 700hp is a lot of happiness going down the tracks me road.
Until your used to it of course!
:rofl:

I’m hoping my one day soon is coming fast. Setting up to build a garage for the toys.
 
Rumble do you have any pictures of those ports?
 
@bigfoot
Yes. As cast or ported or both?
I can get you pictures of the as cast W5 ports by tonight.
I have some ported pictures on the phone I can get to shortly.
Tell me what you want and I’ll post it.

You had that TR on the bench at Charlie’s. Now it’s time to put something under it and make some noise.

Both would be great if you could do it.

Sure thing but right now I’m out and about. I’ll post it this evening and I’ll do a @ your screen name to alter you to the posting.
:thumbsup:

After the garage is built.
 
I’d have to sift through folders of paper work to find our W5 data. Some of you probably remember the “group buy” CNC port deal that Ryan J had on moparts ions ago. We sent one of our sets in on that deal. I can’t remember the “advertised” numbers on them, for some reason 330ish comes to mind, but my dads engine builder just had to flow a port and he wasn’t impressed. At that point I was just like “put it together and see what it does”. It was a 340 block based 4” birdshit crank and rods (Eagle) deal. I think the best time it ran when my dad was wheeling the Duster was 9.89. he only did that once as the car wasn’t legal to run 9’s. All he did was to raise the shift point from 6k to 7200. I’m sure it had more in it, but he just shifted it low and ran low 10’s.
 
…..and if anyone is in search of a project this is up for grabs :)

How much? Not that I would ever use it but would be cool to have sitting in my trophy cabinet.... lol

$450 and I’ll ship. and it’s really weird. You send me payment, and you’ll receive the part!

What are the specs on that intake?
Click to expand...
It’s a mopar 598 intake. Top was cut 1/8” and plunge cut for a 4500 carb. I made spacers for it to fit on my 9.2 deck R3. It was originally on my 9.0 deck R3.
