So I'm building a 440... goal is 500 flywheel hp on 93 octane. Car is a 74 dart swinger 2dr hd top. 4 speed, 8.75 rear with either 3.55s or 3.91(I have both laying in the shop already from previous projects) and a 4 speed.

73 440 block, zero decked, bored .030
L2355 pistons.
Stock Rods and forged crank from a 68 440. Internally balanced.
Torker 2 intake(may swap this out for a Holley SD or RPM intake but I have the torker 2 already so for now, its the default intake for this build)
Edlebrock RPM heads, with crane adjustable ductile steel rockers and hardened shafts. Springs that come with the Comp cam kit will be used.
TTI Headers.

and This cam

Comp CRB XE285HL-10

Should this get me close to my 500 HP goal?
 
Of the ones you listed I would go with the RPM over the Torker 2, although my personal #1 choice for mild 440 is the Holley Street Dominator - and it's still available new.
 
I think you should be damn close, id go solid cam atleast .550 lift make sure you getcorrect valve springs. The torker 2 will work great.... What carb you gonna run?

Street dominator is an awesome intake.... It just works. I have one on a super mild 383 that prolly makes 425 at the motor

Holley 850 more than likely, maybe a 950 if the engine calls for it

you are very close to my build, except for intake and cam. M1 intake and I used a racer brown cam, 556 lift one. I built a Don Dulmage old reliable motor. but added rpm eddies and fender well headers, He told me that I would be around 525HP.

I agree, I ran on on my old 451. Really miss that engine. sold it like an idiot a couple years back.....

I'd like to get one for this build. just this torker came with the block when I bought it so I thought I'd save a few pennies and reuse it but i think it's gonna hold me back some.
 
I think you'll be close assuming the heads are done properly and you use the SD or an RPM intake. The cam might be a little small for 500 hp but you should be within 30-40hp of it. You've got the rockers - I'd run a solid flat tappet.
 
At the top of the first link are dyno results with a 440, RPM intake, Torker II intake, ported factory iron heads and a XE285HL camshaft. You should read through both of the threads as they answer what is possible with the XE285HL in a 440. OOTB RPM heads won't perform as good as the 346 heads in these tests, but will be close.

Regardless of brand, physics and airflow still apply. My 427 BBC .060 0ver =440 made 550 hp. Bore and stroke are the same as a 440 Dodge. 4.310 bore and 3.75 stroke. 11.25-1 compression with an Eddy rpm performer head. Heads for an oval port BBC are 280 cc intake runner. same head in a Dodge is 210 CC runner same head on my 426 wedge. The Eddy victor head for a Dodge is 280 CC intake runner.

Here is a cool fact my 440 BBC made 550 hp and 513 tq. My 426 wedge made 520 hp and 552 tq, with less head, cam and compression. Both engines had RPM performer heads and intake. Cam spec for the 427 was .585/.585 lift and .245/.255 @.050 was a hyd roller.

Mopar 426 cam is a lunati solid lifter cam. .544/.566 with .241//253@.050.

It takes parts to make 500 actual flywheel HP. where you make the power depends on type of parts used. My 426 wedge motor made 516 tq at 2900 rpm with the 210 cc heads.

The larger 280 cc heads will reduce air speed and move the power band up higher. Smaller heads work great on small cube motors, amd makes good torque.

Go to a reputable engine builder and come up with a goal. If you want 500 hp pick the right parts top work in the car the way you want it too.

There's much more to the equation than simply comparing port volumes...especially when you're talking a canted valve head vs a wedge
 
Stick with the RPM intake, I have a 440 with the Edelbrock RPM top end kit. Heads, Cam and intake, on the dyno my motor made 500 HP with 535FT lbs....

the rpm ain`t worth buying if you`ve already got the toquer 2. the torquer will have a little less bottom end(not much tho) and more horsepower up top. some have even found on certain engines the torquer 2 had more low end too.

Thank you. I think I shall simply copy that build then Instead of trying to reinvent a wheel. I wish I was closer, there's no true mopar experts around here.

Have you used the holley street dominator intake on any builds?

I have one, yet have never dyno tested it. My dad used them in the 1980's with good success. See the Dec, 1982 edition of Popular Hot Rodding.

True, on this link, line 46, columns 1 & 2 are direct RPM to Torker II comparisons. The RPM is hard to beat down low.

If you have a Mopar Performance M1 single plane and if fits under the hood, don't throw it away either.
