500 hp 440?

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.

Hmm, so it looks like it'd be a mute point really to try to sell what I have, the torker II, then just buy the RPM as the gains/loss looks minimal at best, its just bascially moving the curve towards a higher rpm...which in my light dart shouldn't affect a whole lot, 416 vs 428 ft lbs at low rpm is still gonna move that thing.

I wonder what a spacer would do on the RPM and Torker II, seems the M1 really likes it.

I believe it's roccodart that has run the 1" spacer on the RPM intake and found it to be of benefit. I know the Torker II has liked the 2" Super Sucker on the 440"-500" engines we have tried it on. Here are two back to back runs with a Torker II and Torker II w/ 2" Super Sucker.

RPM...............TKR II TQ/HP........TKR II w/SS TQ/HP

My friends 440, with a 275hl, ~9.7:1, stealths, rpm intake, 950hp, pretty basic build.

Yep, if you already own them, run them. Anything I would recommend as a replacement would cost a minimum of $480-$700.

Yeah, very low mileage set.
 
Just wondering, I was wanting to keep compression around 10:5 to 1, with the l2355 pistons, my math brings it to 9 to 9.5:1 compression, roughly. What do you think about going with a different piston,
 
I think putting in a modern forging or a modern hypereutectic would be an improvement. Those old TRWs weigh a ton. You will want to be careful on your math until the block is checked - or just figure on blueprinting the deck height to get you want you want.
 
Decades ago, Bill Bagshaw (?) of "Pro parts" fame built a 440 in "Car Craft" that made 511 Hp, TRW pistons don't remember the number at the moment, MP 509 hydraulic, M1 single plane and 750 Holley, ported 906 heads with big valves, was a pump gas build. IMOP, I think the OP is gonna see his goal of 500hp with what he's got; just gonna have to buy ALOT of tires.........................
 
Duke_318 - Not to rain on a parade, hypers are good pistons for a standard street build. My recommendations would be to go to a forged piston, you have more flexibility for future add-on's such as nitrous and they are more forgiving than the hypers. I learned the hard way. and yes, I gaped the rings when this motor was built.

Noted: Thank you.
 
Those KB flat tops would be fine. Those hokey quench dome deals are terrible at what they are billed to do.
 
Well it's done, finally just said screw it, im worrying over .14 compression points, stayed with the original plan and went with the forged L2355s

Yes, I ran the 1" super sucker on an RPM intake and gained 10hp and 12 ft/lbs on the dyno. Nearly identical to what you see on IQ's test.
 
Duke - Those TRW's are great pistons, heavy but very good choice.
 
Would you guys kindly specify if you are talking about Performer intakes or Performer RPM
intakes when you reference them. Thanks.

Yeah, I stuck with them for that fact. with this being mostly a street car, I'm not concerned too much about wind up. Plus, since my forged crank has been balanced before, the L2355s aren't hugely different in weight over the 1266 Silvo Lites I had orginally, so it'll save me some time and money on the balance machine. Plus I couldn't find a lighter forged piston in my budget of 600 that would give me what i wanted

Plus...down the road if this engine doesn't do what i'd like...my buddy just gave me a 440 out of a 76 truck with 452 heads on it for free so I can build another :)
 
A four hole spacer (rather than open spacer) under your carb will net you a little more bottom end torque with the TII.
 
496 stroker torque @ 3000 rpm

1) Torker II.................................................514 lb-ft
2) Torker II w/ 2" Supersucker 4 into 1............517 lb-ft

Very nice numbers. I'm curious now to see what a ported Torker II will do, ill even supply the manifold for the test if you return it .... hint hint

What you don't like the smileys?
