Sorry for being . But Zippy what would it take for mopar to bring back the M1 tunnelram in big and small block form?? Why did mopar stop making them?? I loved the one i had on my 440 and i really like that it would fit under a 5 inch high hood scoop.Thanks Mopar65

Andy the RAS rockerarms looks interesting, who sells them?
I need the best rockers out there, RAS or TD?

Good looking engine.

Depends how you define "best". I consider the RAS rocker arms to be the very best choice for street driven roller cam setups. They are strong and they won't break like aluminum rocker arms after X number of cycles.

For drag racing then something like the T&D or the Jesel rocker arms would be "best". Also, the RAS only come in 1.50 and 1.60 ratio so if you need 1.75 then the RAS isn't "best" anymore.

RAS only sells their stuff direct so you have to call them and order the parts. They do not sell thru any distributors or dealers. They only make the investment cast 440 rocker arms once a year so when they are gone they are gone. You'll have to call them to see if they have any on the shelf or not at the moment. I saw a set in the parts for sale section last month so you might get lucky there.

Thanks Andy

It's for my all new super tricky 440 sixpack super stock engine.
My new block is on it's way over here.
Now I ned a set of mopar stage V steel heads with 2.08-1.74 valve seats
Can only find 2.14-1.81

Sorry of topic

take care

RAS don't have them right now, Coke Bottle Kid was the one selling his used set. They are planning to make more, it's just that it would take some time.

Stage V takes a different offset intake rocker arm doesn't it? So you might need Harland, Crane, etc.

Zippy,

Cool deal on the 337 intake. I ordered one even though I have no idea what it looks like. Guess I'll post some pictures when it shows up so everyone can see.

8 intakes on B/O And 11 in Transit To Warren THat means Only 3 avaiable after B/o Fill. Andy you dont Like HArland sharps ? Had them On My 451 Stage6 low deck.6600 shift point and lash only backed of on 1 valve after 3 months .003, we checked them reguarly, i got sick of pullin covers.Zippy i Know the Mopar Parts system i was around when Lewandoski&Couisneau were at Direct Connection.

When did I say I don't like Harlands? As far as I know they are just fine for the correct application.

You didnt say, was just looking for your opininon and WhO is Ras and how expensive are they? , do they have a website?

Did you get your 337 intake yet Andy? They're in warehouse stock.

For anyone who doesn't know what that intake is and actually CARES what that intake is (if so, congradulations), it's a 4150 flange single plane, Max Wedge port RB intake for standard (Not stage VI) heads....so it's a standard width manifold instead of the extra-super wide Stage VI version.

It's kind of an odd duck in that MP always pushed the Stage VI head, so the extra wide manifold outsold this one big time. But with the Victor MW heads (or for that matter even iron MW heads) it should be a nice piece. Looks like it is very easy to convert to 4500 also.

Another one, for no particular reason. I'm glad we were able to resurrect this intake from NS1 status, it has it's place for sure.

I've never heard or seen one of those before. Even though it looks similar to the dedicated Stage VI RB intakes, I can tell the plenum for the 4150 version (assuming there are both 4150 and 4500 types) is at least different than the Stage VI intake... which can't be bad, 'cuz out of the box the Stage VI intake SUCKED. Of course, after you spend a bunch of $$$ w/ "Dr. Air" it makes some HP.

EDIT: I'd be curious how tall the intake in the pictures above is.

Cool deal, the missing link exists!

I haven't gotten mine yet but it should be arriving anytime now. The price on that intake was pretty cheap, I think the dealer told me $200 or something like that.

I'll be able to see shortly whether it will fit with Indy or Victor heads. It does appear to be the only way to use stock type Max Wedge heads on an RB since there isn't a bathtub intake gasket available. So if a guy got some Performer RPM heads ported to the MW size then that intake would be the way to go.

I've heard that MP is going to get a little more serious about the Max Wedge heads, if so then this intake would be a good one to use.

Andy whats the Pn for the heads? Yours are Different than what Mancinis price is, Are they a Stage 5 redone in aluminum?

They are the MP '452' heads that Mancini has CNC ported. They are in the latest flyer for $2650 a pair but maybe the price has changed since the flyer came out? They are not Stage V heads and they certainly aren't Stage VI heads. They are basically a straight plug version of the Edelbrock RPM head.

Brad,

As said....that intake is an odd duck. Unlike the "normal" (if there is such a thing!) M1 intakes it has MP's 4500 plenum, but with the carb pad filled in for 4150.

Good points on the fit also. It might look a little strange on Victor mw heads, and would require a valley pan underneath the integral pan that is already there....But can't think of any reason why it wouldn't work

I wonder what the 1000HP works like in traffic with those big bores.

If it's anything like my 1000 Race Demon, it basically works like an on/off switch. Sure it makes 7 more hp than the older 850 annular but the annular carb was much more linear feeling and easier to drive. But, hp is hp...
