For discussion, this is the X-celerator with the Mr Gasket 5840 gaskets. There is a lot of meat left in this intake.For a performance stroker I'd never run a dual plane, ever. In the OP's situation I'd run the Weiand and be looking for a used Victor.
I ran one on my Edelbrock headed 340, it took a bit of work to port match, but it worked well. IMHO, it's borderline small for a stout stroker, that's why I recommended the Victor. The Victor that I ran on my 408 took a ton of grinding to port match, it had a lot of core shift.For discussion, this is the X-celerator with the Mr Gasket 5840 gaskets.

I wouldn’t run away from an M1 if I had one laying around.
You think a little less aggressive for a street/milder motor with the curved runners?

I think that intake surprised me last winter after flowing one for a member last winter. And we also have a member running 6.60’s in his beautiful duster with one. We will be seeing how a Victor340 stacks up against it soon hopefully.
My guess is that between an M1, Excellerator, and Victor , with all ported/ port matched, and installed on a cookie cutter 500/550 horse bracket stroker motor, the ET difference between all of them would be negligible, at most 1/2 a tenth.
I never seen or touched an Excellerator and would like to but if that’s what was on your old engine they work well. So I agree any of the above with a little tender loving care.

How is the low end with the Trick Flow? I bought their heads I figured I might as well get the intake. I know on Powernation it matched the dual plane on the low end on the stroker they done.I'm impressed with my out of the box Trick Flow intake and how it performed first time out in my new build. I have yet to run anything else worth noting so not much to compare to right now.
I vote for the Weiand 1995.I have started assembling my 340/420 and I need to start deciding on which intake to run. I currently have the following two intakes:
Non-Airgap RPM
Weiand X-celerator (small single plane)
I have gasket matched both of these to the same intake gaskets, and the depth of the match is about the same for both. I have also matched the intake openings to the carb gasket on both pieces. My worry with these is that they were made for 318-360 cu inches when new and now even with the gasket match, I’m guessing that they will still be a restriction for the 420.
I am also trying to decide if the new Trick Flow single plane or the Indy 360-3R single plane may be better options too at about a $30 difference in price between them brand new. I know the Indy is quite a bit taller, but I am running a drop base air cleaner with about a 1” spacer under the carb with the current RPM intake. So, I am fairly sure that the 360-3R will not have a height issue under the hood (Challenger with RT hood).
My main concern with the top two are, if they are going to choke down the engine or not. My main concern with the 360-3R is if it is too big for a streetcar that will be maxed out at 6-6200rpms or so and has a solid lifter cam of 252/256 @ .050” with .603” lifts (before lash and geo loss).
My 727 Dynamic 9.5” converter was spec’d for my 340 with a 226/238 cam. So, I am assuming that the flash rpms will move up from 3800rpms with this new setup.
This is my street toy with no power steering or AC, and it has manual front disc brakes. So which intake would you suggest?
Thanks!!
My preference for street is the Performer RPM Airgap. Dual plane for better street manners.I have started assembling my 340/420 and I need to start deciding on which intake to run. I currently have the following two intakes:
