My mild steel 8-point bar added about 100#, FWIW.
I, too, think the Performer RPM is the next choke point. Got the hood clearance to try a tall(er) single-plain intake like a Trick Flow?
Did you ever state your performance goals? I’m currently right against the hood with. Drop base 3” air cleaner. So anything taller than the RPM is out. I think that wile the RPM may not flow what a victor does, I think it does good things for my heavy-azz car. While I’d be willing to try an M1, I don’t think the car would be any faster, and I think I’d be shifting higher for the same ET. Could be wrong, but it currently pulls pretty good between 4500 & 5500. Goals are to be faster with no specific ET. Im a bracket racer and I’m currently usually the slower car in the local Pro ET class, which is full of mid to high 10’s cars. I’d like to be the hunter once in a while instead of constantly being the hunted. Low 11’s will Have the race in front of me now & then. More MPH at the stripe would be nice as I feel the faster car always has better options. With that said; a 10 second time slip would be the next benchmark I’m looking at. I don’t want to get hung up on it, but it would be cool.

I agree w putting the cam in sooner. Mine is at 102 or 103, on a 108.
What are your 60s? Jw, as our et/weights are pretty close.
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.
Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.

It’s generally in the 1.57X range on the typical 11.55 run. In good fall air last year it went a best of 1.548.

Your comments about wanting to get into the tens make me think a bigger cam, single plane intake, bigger carb, and restalling the converter to 5,000+ is the way to go. And it sounds like you don't have a cold air system? That is leaving a lot on the table. I would do any gear change last. Consistancy at this power and speed level come from back to back 60 ft numbers, and accurate shift rpm. When i was running 9.50s and went to an airshifter with rpm switch, i saw my times narrow by .02. Having the 1/2 shift happen further down track is a help, and once you have the cam/converter combo up well above the torque peak, the old rear gear ratio has less Effect on ET, but good effect on cosistancy.

I was wondering if your car would go any faster with the Indy dual plane that I run. As far as I know the intake comes in standard port and can be opened to Max Wedge size easily. I believe it has bigger runners then the RPM and I don't think its any taller. Just a thought as that way you could still have the good low end of a dual plane and it should outflow the RPM you are using ? Just a thought ? Ron B series engine, Ron. I don’t think Indy makes the 2D for a B, do they? Onsidering hood clearance, the only viable options to me are the M1 or maybe a victor. But again, I like the torque curve and shift points down low where they are now.

I have wondered how the Indy dual plane stands up to the RPM as I believe the Indy has larger runners. Good luck with it. There is also the Mopar 337 single plane that is not to tall. I hear its a pretty good intake. Ron

Hey Greg, the cam would likely be my next engine move. But I'm hoping I'm done under the hood for a while at least. Current cam, as outlined, is a pretty good lobe profile (Engle KV-3) topping out at grosst .573 / net .555 lift. So I'm leaving a decent amount of my heads potential on the table. Going to a 1.6 rocker, or simply more cam to make use of the heads potential up around .600 valvelift seems like it would yield results. But I realize that is only a theory. Not sure about your carb thoughts. Currently running a 1000 4150. I think this carb is plenty. Don't want more converter because I drive this car on the street regularly. Basically, as long as I get near bottom 11's, I'll be satisfied and turn my future efforts towards shedding weight, as that would not only help it go a little faster, but also make it easier on parts.. The car currently carries every bit of its factory stuff. A nice fiberglass hood, bumper, and maybe removing the original am radio in favor of a delete plate, along with a few other tricks could negate the weight of the bar, and effectively move that weight rearward. Can't wait for spring.....

Gary how does it run with the exhaust hooked up? Weren't you running a pretty small exhaust with Flowmasters?
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

I will be following along here. I have more cubic inches, and the combo is nowhere near sorted out, but the intake aspect of this sure interests me.
1969 Dart GTS 340 1969 Super Bee X9 N-96 1969 Coronet R/T X9 N-96 2015 Dodge Dart GT 2019 Ram 2500 Big Horn. Looking for the original block for my Bee. The last 4 are 7449

Though the infamous "Silver Bullet" is more your breed, That would be a great clone
71 demon stock stroke 440/indy ez-1 running 10.10 @ 132.14 mph in the 1/4 and 6.36 @ 107.46 mph in the 1/8 not in the same weekend but It did it then I sold it. 67 Belvedere that worked it's way in the 10's

It does have a full "street car" 2-1/4" exhaust system with Flowmaster 40's that was near new when I bought it over 10 years ago. I put 3" head pipe 16" off the headers with 3" cutouts on it that I open at the track. I jet the primaries down a couple when it's corked up. I believe the exhaust would cost it 2 tenths or more.
