OK --I have built a LOT of Mopars--no two alike ( that may be part of the problem) but...
Have and order for a stock block 511 style STREET unit
Buyer wants a mildish hyd cam loads of TQ and great street mannors--He is just crazy about an A&A Maxie style crossram so...let the ideas flow here--I am sure we will use a non max wedge port maybe Sidewinders or perhaps Trick Flows he wants a cam that you can hear but not too big--will run some good headers like TTI--I want to run the smallest diameter possible so they fit easy as pie with no hassle--want a Hemi 6 qt pan so nothing hanging below the K Frame too bad
I am talking Simple--no big RPM--best rockers and valve train
10:1 that purrs but will pop the windshield out of the gasket
The biggest factor here is that damn intake carb set up he wants
Andy--what would you do???????????? Everyones opinion welcome but please try and speak from recent experience
Big HP numbers are meaningless here Think of it this way --he wants EASY to live with and drive anywhere ( after that intake warms up) and big big TQ
So.....????? Laroy where are you?? Comp Wedge?? Other builders --what do I need to do here--cam lobes that are easy on stuff no max under curve computer BS -- Stone Ax reliable Really think about LSA on this one and...I really prefer flat tappet I am just not in the mood for dealing with hyd roller lifter issues and bronze gears
OK GO!!!

505" 440 block with 4.25 stroke and 7.1" Molnar rods and crank.
10.5 CR
Modern Cylinder Head ported Stealth heads
Howards hydraulic roller .545 lift and 235/241 @ .050 duration installed straight up with 1.5 Crane rockers.

3" full exhaust with Dynomax Ultra Flows
275/60/15 MT Pro's
6 cylinder bars and SS springs.

I went to hydraulic roller after a flat tappet failure. Use the Crane composite gear and the Howards bronze tipped pushrod if you are going mechanical pump.

I looked long and hard at the crossrams and finally chose to go a different direction after reading Andy's findings. They sure do have great eye appeal, though!

For headers use the Hedman 78030.

Only way to make a cross ram really street friendly is to go EFI. I'd talk to FastMan EFI to make it happen. I think a pair of throttle body injection units should work pretty well.

I'd use a Mopar .528 flat tappet cam or the aftermarket equal. You can also get that grind in a hyd flat tappet, I used one a few years back in a 470 stroker with exhaust manifolds. That setup was killer. It idled nice and smooth with 16 inches of vacuum but would pull your head off all the way past 6500 rpm.

I'm working on one of these right now. It will have TF heads, a CH28 intake with dual FiTech throttle bodies and a fairly mild cam. The guy wants a ton of torque without having to fiddle with it all the time.

Who does that .528" grind in hydraulic?

My 9:1 493 with an MP509 did 600 ft/lbs @ 4000 and was over 500 ft/lbs from 2000-5000. When it fired on the dyno I figured it would be a stone below 3000 based on how choppy the idle was but it was already giving the big needle a swing on the Stuska by the time it hit 1500.

Displacement is your friend when you choose the less than ideal cam...

RPM heads with the valve job fixed, M1 single plane and Commander 950 Pro TBI.

Sounds like you have most of it figured out already(heads, intake, etc).

I've dyno tested a few engines with the oem x-ram and they were very well behaved.

This is a situation where I wouldn't try and reinvent the wheel.

My choice would be the biggest Howard's Rattler cam, hyd or hyd roller, your choice.
If you felt that would be a little too choppy for the owner, then drop down to the middle one.

I have a set of Stealth heads here that are destined for almost the same thing, only I opened the port entrances up to MW size to use the OE intake.

I have used some of the Howards rattlers darn cams run great and sound good too--and they are available--so many Mopar part numbers are a wait deal these days

Does anyone know if a stock max wedge set up with air cleaners will fit under stock 69 Roadrunner hood???

Thanks

What a great pic. Were you trying to get it perfectly square to the divider centerline making it a true visual compairison?

I wasn't really trying to do anything other than getting the ports in the middle of the screen on my phone.

After I had the first port done, I figured a pic of the two might come in handy at some point.

Would there be any benefit in raising the roof of the port but leaving the floor as cast, to keep velocity up for smaller/street oriented engines?

On the heads I did, what the motor makes for power isn't the top priority.

They have a factory x-ram they want to use, and just want a cam that's basically zero maintenance and lumps a little, and they needed some heads for that.

I took a MP MW intake gasket, bolted it to the heads and scribed out where the openings are and made it so the intake "should" line up with the heads.
