Stock 383 road runner cast intake manifold vs original Torker?

What I like less weight with the torker.

The 383 spins up fast and the torker helps it maintain those rpms. I won several street races against some furds and chubbys back in the day.

tx guys...i have both and am undecided. Was hoping someone had swapped theirs and had the evidence.
MWbird...do you remember if lo rpm power was ok with the Torker? Car will never be raced, only street driven.

That Torker intake is a single plane as you know and loves 2500-6500 rpm if memory serves. So for my current combo it’s matched (cam,Holley 750, stall, and 3.91) stock it wouldnt didn’t have and off the above except then 4.56 gears. I think maybe back then a higher stall mighta helped some but motor was all stock except intake cam and gears and headers. Honestly it was kinda slow but in 86 the motor got treated to 11.5 pistons .484 cam stall 3.91 gears stock manifolds and gasket matched heads and I’m very happy even these days with my combo on the street

Torker low end and stock I wasn’t pleased but I was a kid on a budget and in 86 time to do it somewhat to the old DC parts catolog recommendations

also have 516 heads

See the link I posted.

Torker is the last one tested.

They tested them all with no other mods to the engine.

You can use the "Performer" as a substitute for the factory iron intake, flow wise.

Or old school Chrysler DP4B as sold in the day and turn up here time to time

I always liked a dp4b for dual purpose 383.

Still i have heard guys say their 383 with the Torker worked well at low rpm. I'm guessing they had better compression than most stock 383's which were generally quite low and a short duration cam, but even so this flies in the face of the common belief single planes are poor lo rpm torque producers? I'm reading (i know) that a dual plane with longer narrow runners produces better velocity and longer pulses which produce torque. Scratching my head i went out to the shop and noticed something. The b and rb blocks are very wide and that Torker on my 383 has long runners ...and they are quite tapered which should increase velocity. Maybe this could make a difference?
I can't believe i typed all that?

Tbh it didn’t work good at all with a factory torque converter

 

[ir3333]

a lot of factory 383's had very lo compression and with a big tire and 3.23's they were lazy out of the hole with a dual plane manifold.

There you go

DP4B is more comparable to Performer RPM than standard Performer (actually about 1/2 way between).

Standard Performer was a near exact copy of the factory iron manifold in aluminum.

this going in your 68 Dart.

Me too!

Don...i have a 372 going into the '68 GTS. I recently purchased another '68 GTS that will get the 383 if i live long enough.

You love your Dart,me too,the right 1 has not come my way,booth builds no doubt from you will be stunninng, love the 383 in a Dart right combo your building.

Getting so hard to find authentic muscle cars to restore. I sometimes wonder how many are left?

On my 70 383 I ran the original iron intake, then a DP4B on a mostly stock (headers) car and noticed much better throttle response with the Edelbrock. After that I rebuilt the motor with "3/4" Crane cam, TRW domed pistons and a B motor 6 BBL setup. Ran way better than it should, switched to an original Torker and a 780 Holley, both the six pack & Torker performed about the same. After the rebuild I ran a 3.91 for a few years then switched back to the original 3.23 gears. Obviously, throttle response was better with the steeper gears but even with the 3.23's it hauled serious a$$ with the Torker at that point.
