BB roller cam recommendations

440 .30 over , 12.1 flat top,indy ez heads by compuflow,dominator,2” headers,1.80 glide,4.88 gear, 32x14,2811 lbs with driver. Foot brake bracket car
Flow numbers 347@700 on intake and 232 @700 on exhaust

I would look for a cam with between 260 and 270 @ .050 with as much lobe lift that you can get and have it ground on a 108 LSA and install it between 103 and 105 ATDC on the intake lobes
Make sure and get enough spring pressure and stiff enough pushrods to go to 8000 RPM
Take the time to test shifting the motor between 5500 in 500 RPM increments up to 8000 RPM and then shift at the RPM that makes you happy

Max Wedge or standard ports?

What's the peak RPM the engine sees on the track?

What's the converter stall speed?

And, what rockers arms...... and what ratio?

If that's a stock 440 block. Get a cam that won't need a lot of rpm. A 440 block won't take 8000 rpm very long. I wouldn't run it over 7000 rpm.

2800 lb car with 4.88 gears gives you a lot of flexibility on the cam. I'd be interested in knowing in how much power you're trying to make and if you want to get aggressive with the cam or have something that goes rounds without any maintenance.

If it was my car I'd probably use a street roller like the XR292R from Comp. That should make good power in a 440 with 12:1 compression and EZ heads without beating up the valve springs. I'm assuming 1.5 rocker arms?

this is approximately the combo my 1933 dodge panel project will end up [with me in it], but i will be using 32/33" tires, and looking for mid level maintenance.

This is close to my combo also. I'm running a .030 over 440, compuflow ez-1's at basically the same flow you have. The difference is I have 13:1 and a 727. Also weigh about 3400 w/ me. I run the old .690 comp roller. I believe it's 282 @ .050. I've put 3 passes on it so far. No tuning and it went a best 10.24 @ 132. Rear is dana 4.89 w/ 33 x 14.5 slicks. Shifting at 6500.

Hs 1.5 harland sharps and max wedge port.
Only made couple of passes with .650 lift 290@.050 old comp solid. 6.35@108.9.97@131 in 1/4.

290@050 is way too big for your combination. That cam is killing the torque and slowing you down. Sometimes bigger is not better. I think the 292 street roller would work or you could go one size bigger with a 260@050 intake lobe.

Looks like you're crossing the stripe at roughly 7000 rpm with those gears. With a better cam you should be going faster so you most likely will need to drop the rear gear down to 4.56 or even a 4.30.

A 440 with ported EZ heads and 12:1 compression should make 650 to 700 hp if you have a good intake manifold. That would put you into the low 9's at 140+ mph if the chassis is decent. So I'd gear the car to go 7000 rpm at 145 and then pick a cam that puts peak power around 6800 rpm. 260 @ 050 should be in the ballpark. Probably need 5000+ stall on the converter but I'm no expert there.

I run an Isky solid roller in my 470 low deck with home ported rpm's and .680-.660 and 276-281 @ .050 and it has many street miles and a few passes with a 6.15 @ 112+ so far on crap QTP's.............

My mate's 440 Dart made 600hp with 320cfm Eddy's, old .590 sft purple@12.5:1, 1050 Dom etc. Working on your no's, 2811lbs/9.97@131 your only making 560hp, something wrong, you should be up in the 640+hp range with those speccs, I don't think its the .290@.050 cam personally....I made 530hp with that cam@9.8:1 an 850DP and 260cfm 906's back in the day.

Yes something in the combo is not working. My dart has a 446 with Sr heads that flow 290 and has a .557 mopar cam, speed pro pistons and a 750 carb. That car runs 6.60s @ 3300

My perspective is a bit simplistic, but MW ports, that much duration, and only 450-ish cubes is killing your torque.

Add my vote to those who are suggesting you should try something 20 to 30 degrees smaller. If you're going to switch to a roller, you might even be able to pick up some lift, too.

The 290/.650 cam was designed to move air in and out of cast iron heads. The Indy heads don't need that much duration, it just makes the engine lazy. Put a smaller cam in there and the engine should perk up. Before you tear it apart check the cranking compression and then recheck it with the new cam. You'll most likely need to change your ignition curve and re-jet the carb too since the smaller cam will make the engine more efficient. Take a note of your manifold vacuum at idle before and after. It should go up by a bunch.

While I’ve never been a big fan of the 650/290 solid, it did have its place.
But imo that place isn’t MW sized Indy heads on a 440.

That being said, I think the xr292r is too much of a step in the other direction.
Sure, it’ll work okay......... but I don’t feel that cam in that combo is going to make the best use of a roller set up in a 12:1 bracket car with decent heads.

I'd been thinking my COMP RX 265 / .650 / 108 might be a good choice, or something close to it. Wasn't sure if the OP's MW ports vs my standard ports made it less of a viable option.

This maybe a good choice?>

That would most likely work better than what the OP has now but my guess is that it is still 10 degrees too big. I tried a 270@050 cam in my 470 with TF heads and it was too big. That engine worked best with cams in the 260 range. The OP engine is a little smaller but has a bit more compression. My guess is the OP's engine will work best with a cam in the 260's.

Looks like it's laying down after the first 1/8...mph is down alot compared to the 1/8 mph.

What does it 60ft.? Fuel system?

My sons .496 has a .637 279@.050 roller with edelbrocks. Runs 6.00s in 1/8

No real benefit to limiting yourself to what’s available in a catalog.

As a reference, Dyno Sim gives me the best numbers with a 270/276 at .050

for my 12.5cr 470.....

Does the simulator consider head flow? Does it give different results for flat-tappet vs. roller cams?

yes for both...........

A 290@.050 cam and Max Wedge port with only 446 cubes means you should be turning a lot of rpm to make power. Like ou812, I don't think it's making power on top. My first suspect when I see this is valvetrain instability, and may be why it's laying down. The bottom might be a bit soft from the big cam, but you could crutch that a bit with the converter. But, if it won't rev, that's an exercise in futility. Make sure the rocker geometry is right so the valvetrain stays stable, no matter what cam you choose to go with.

If the motor is 446 cubes and has 2.19 intakes, Vizards LSA chart asks for a lobe seperation that is rather tight. 104! If a single pattern 270 @ .050 cam is ground that way, the overlap at .050 would be 62 degrees, letting the motor breath. I definately don't have enough experiance to pick a cam that is perfect here, but looking at 62 degrees overlap combined with no more than 270 @ .050 total duration in straight up will allow a resonably early intake closing of 59 degrees ATDC. Sounds logical to me. Use a 6,000 + stall minimum due to the glide, shift it at 7,000?

I don't have "the" answer for you, but can give you something to think about. My RB 452 has less compression (11.5) and standard ports, but comparable flow #s. Dwayne Porter spec'd a 265 at .050 x .650" on 108 LSA solid roller, which made peak torque at 5100 and peak HP at 6900. Your MW ports would probably push the peak torque & HP RPMs up 300-400 over mine.

I don't recall what you may have for converter stall or what RPM you're willing to spin your engine, but you may be able to better predict what size cam suits your combination based on this.
