Torker 2 vs Performer RPM

[SRT-440]

Right now I have an old Torker 2 (single plain) intake on my 383..will a RPM be worth swapping out? The motor pulls really good up top but it's low RPMs and mid-range is lacking.
If I do swap them, do I need to buy a new valley pan gasket...the one on there now isn't 6 months old.

What cam are you running? There was an article a year or so ago on all of the mopar intakes. The torker and torker 2 did exceptional compared to the other intakes. Depending on your cam specs the rpm may not yield much better results.

I don't think the Performer will help much on the low end problem....The Torker, while an old skool outdated intake, it is a good intake even by todays standards.
I'm thinking your problem lies more with camshaft, and a stroke less than that of a Small Block Chevy.

[SRT-440]

I'll have to get the specs on the cam...but it's on the bigger side (im drawing a blank but i think its a comp cam XP284)..it's running close to 12.5:1 compression and soon to have meth injection...it's got decent low end but I have a chance to pick up an rpm for cheap so I'm trying to decide if it's worth the trouble.

[c00nhunterjoe]

Good lord, 12.5:1. If its a 284 then I would leave the torker on it. If its smaller then the 284 and you have a good deal then try the rpm. I would bet you won't see a 2 or 300 rpm difference

[SRT-440]

Lol...yea high compression but the injection will help a lot and let me run 93...it runs awesome at wot...breaks the drag radials lose at 30 mph. Just seems like the throttle response could be better...might just be the combination like cooter said.

I was always under the impression that the Torker manifolds were for mid to upper RPM power making-I had one on my 440 and that's the experience I had with it.  Isn't the Performer RPM a dual plane?  That would address the lower RPM issues...

From what I've heard torkers are from 3500 rpm and up...like I said, at wot it screams but around town it seems sluggish. The rpm is a dual plane which is said to be better from 1500-6500 rpm

3.38 Stroke VS 3.750 Stroke...Bottom end solved.

I think you will like the Performer RPM. I'm running one on the 440 with the 509/292 purple cam. It works in it's advertised range and the power does not fall off in the top end. I would only choose the Torkers for a dedicated drag car.

[c00nhunterjoe]

I will have to find the article. The torker outperformed several dual plane intakes but it soundslike you have other issues.  Throttle response will be more of a tuning aspect then an intake swap.

I missed the torker 2 part. I run the torker on my 383. Here is the article. Hotrod was extremely impressed with the torker intake. Be sure to note the torker vs edlebrock rpm numbers.

And part 2 with a cylinder head swap. The rpm had a couple extra ponies to offer but not much.

Interesting, I would not have thought that. Good find.

I have always argued that the torker 383 is a great intake. I've had it on my car for a long time. Its extremely streetable behind my 383. 11:1, RB cam close to the mp 509, basicly stock 906's. The car turns mid 12's and has a great powerband. Its very tame to cruise at slow speeds, even with the 4 speed, and has plenty of power when you lay into it. The power band is very useful. Despite the disadvantaged short stroke, it rivals a few of my friends with 440's. Its a fast revving engine.

I was tickled pink when that artice was written and thos numbers were posted. It confirmed my "seat-o-pants" meter

Is it a Torker 2 or an original Torker ? I've never seen a lowdeck Torker 2 and wasn't aware that they were even made. 

The torker and torker 2 are different manifolds in terms of performance and appearance. Post a pic if you can so we can see what you've got.

Ok I feel like an idiot   it's a Torker 383...I don't know why I keep calling it a T2...with that being figured out I guess there wouldn't be any reason to swap them in light of the Hot Rod links above.
It def needs some tuning...has a odd stumble off idle (does it in park also) almost like it doesn't want to rev...but once it gets above 1000-1500 rpm its fine..pulls hard after...rebuilt Holley 750DP..has to be timing/carb. Gonna play around with it this weekend.  

[firefighter3931]

I kinda figured that's what you had Rick  Looked online and couldn't find anything on a 383-400 Torker 2 

It sounds like a lean off idle stumble. You might need to increase the squirter size on your 750DP to eliminate it. What cam are you running ? Where is the timing set at ; initial @ idle and total at what RPM ?



Ron

[SRT-440]

Cam is a comp cam XP284...can't remember off hand what we set the timing to..I have it written down at home...it's been several months since we set the timing. I know I'm not much help...LOL!
In the meantime, is there a "ballpark" that would be a good starting point?

[firefighter3931]

The XE284 is a healthy cam so it'll want lots of base timing @ idle. I would bump the initial setting to 20* BTDC then check what the total timing is and at what rpm it stops advancing. You might have to do some distributor mods to limit the mechanical advance.

If the engine likes 20 at idle then you only want 16-18* mechanical advance for a total of 36-38* preferably "all in" by 2800-3000 rpm.

Big cams like lots of spark lead 

That Torker is an excellent manifold....i don't see any reason to swap a Performer RPM in it's place.

I would be that holley needs tuning. Bigger squirter will probably help and changing the cam on the accel pump to start. Might have to upgrade to a bigger pump, the 30cc may not be enough for your comboo. Your build is similar to mine and I had the same off idle issues you describe. Carb tuning fixed mine. 4779 holley dp is what I'm running
