W2 Mopar inspection w/RAMM

What did you do 15-16 years ago with W2’s? Is that the set I called you about back in 2010-2011? Think you had them on your car if I remember correctly

Actually it wasn't W2's but it was me trying to turn some LA's into a set of W2's. I machined a set of "J" head pushrod holes to accept solid slugs of aluminum rod with the intention of porting the intake side into the exact shape of W2's. After several hours of work I had pressed 8 solid chunks of aluminum rod into the pushrod holes and began shaping the intake runner into a W2. I worked the bowls the intake guide boss and really thought I had a weapon on my hands. At the time I did not have a flowbench but I did know a guy that had a SF-600 and dropped them off there. He called me when he had tested them and I went to pick them up. I had acheived a whopping 237cfm @ peak. I was so disenchanted I tossed them in the scrap bin. I kinda wish I hadn't now but it taught me that the runner doesn't have as much to do with it as I thought. The material just isn't there in a LA casting. J.Rob
 
I'm sure those heads would have made more than enough power without the pushrod pinch modified.
Dan smith (Qwkmopardan) makes plenty of power with just a ported set of 587's on his 410 ci smallblock.

Sorry to read of the Batten loss. A horrible thing.



Love it!



With rectangle ports... I think that is how most people see it.



Most people will say the W5 is a rectangle aluminum version of the W2.



IMO, A factory hp/light race head in aluminum and iron are the W2-5 set. As cast they more a good bit more air than a stock head.
The W-7-8-9 are race heads. Extra bolt bosses are a key. There own family if you wish to see it that way.

The W5 head is a raised runner while the W2 is a standard port location. People may say the W5 is an aluminum W2 but it ain’t.
 
"You sure? That equals 426cfm @ 28" h2o."

That's why they ripped! lol
 
The Batten heads were the aluminum W2's. and where the W2's came from. From what I remember Batten made Oldsmobile heads. I had a set of oval and square port batten heads. I liked the square ports they were like the Indy 360-1 we have now. W5's were great heads but finding what you need to use them was always a problem with the raise ports.

What parts? The raised port head had an intake from MP in 3 flavors. Single plane small port, large port & a tunnel Ram. A 4th, short lived dual plane *I think.*
 
Ramm,
What size valves are in those W2s, and are they going back on the same 371” motor? Do you remember what kind of numbers you got out of them after you ported them?

The same valves are being re-used 2.055"/1.60" and they went 285-286 cfm. J.Rob

Several years ago I looked at a R engine out of a roundy round dirt car. It had w-5 heads but had a W-2 intake with quiet a bit of welding done to it. I asked the owner about it and he said his engine guy liked the W-2 intake better.

I can see that. A lot of work must have went into that intake with the port reshaping. With the W5 selection, they re-drilled the LA-M1 to fit which is fine enough for the street and light drags and then had the large port intake single plane for the single 4bbl. racing applications.

I would select a 400+ cube as a determining factor. It's just an arbitrary method and that's just my own thoughts. J.Rob

I’d imagine that is also combined with what one is doing and how hard it is being pushed. Good answer to a good question for new to the W2 people.
 
How would you go about utilizing W2s in a stock appearing application ?
Cam specs , intake porting etc ...
 
Only the early original W2 castings resembled stock heads.
The newer heads have their own “look”.

As far as using them in something like FAST, they wouldn’t be legal....... since the rules stipulate you must use the “correct” castings for the combination(or one of the approved alternatives).
 
I have been following the FAST class racing on youtube and thinking aboutwhat itwould take to build a small block A-Body to be competetive.
I have no illusion that you could outrun a Hemi but think one could be impressive .
I was thinking ported W2 Econos , TQ competition carb , extrude honed exhaust manifolds...etc .
But what kind of cam grind ?

I’d suggest perusing the rules before buying any parts.
