I agree, my Scott Brown cam was way off with the 112LDA. My car couldn't get out of its own smoke with that cam. Don't take it wrong, but sometimes the cam has to be matched to the converter etc. IM sure you and MR P know what you doing, just saying. My buddy has a Nova, 3600lbs street car. Scott handled the cyl head porting, and the cam. Its a 565 BBC and it runs 9.30's . We haven't lit the plate yet....LOL There are a few good suggestions in this thread, call a few and see what they say. My car runs pretty well, and I don't question Scott, whatever he says...I listen LOL A lot of fast cars out there have Scott Brown cams in them and they don't even know it, only because a lot of tuners go through Scott and don't tell their customers where the cam came from or who spec'd it. Hey I understand, not everyone will get great results and that's why there are a few great guys out there to work with. Honestly I would talk to Dwayne ( I have never worked with him, but many here have) and or Scott. I think that's all you need to get a great cam for a Mopar
....BAD A$$ STREET CAR.....

calling cam companies
You're not going to get an engineer on the phone. That's Buffy-the-phone-girl, reading a prepared response from her screen. Not her fault, she's limited to recommending at least one product whether it's best for you is not her problem.
Another problem: understanding cams has 2 distinct subjects which overlap by accident:
1. how do the whirley bits function (this has naught to do with engines and combustion, just metal, springs and geometry - especially rocker arms)
2. what does the engine want the valves to do (and doesn't care if it's by pneumatic, solenoids, or pixie dust).
Just my 2¢? I don't know anyone of Harold's quality that you can get on the phone. Some of his comments are still on Speedtalk.
After 50 years, your radar gets really sharp at picking up "he sounded good, until he said that really stupid thing" (name on request).
Why you see big LSA numbers with big engines: they need HUGE duration, and that LSA is how they hide the overlap.

These "who do I call" questions come up all the time... I can remember 15 plus years ago calling a few cam companies for a solid roller for a car with exhaust manifolds. I got so frustrated because I could hear the juice bag on the other end of the phone turning the pages. I didn't take any of their reccomendations, I basicly had a idea how much duration I wanted and knew how much lift would fit in the motor. I told them to spread the lobe center out as wide as the cam core would support.
Then through Ryan Johnson I heard of this guy Dwayne Porter that works with comp and had a very wide scope of dyno testing all kinds of racing engines...From 2 bbls with exhaust manifolds to stock eliminator to boat stuff. I gave Dwayne a call and tapped into his expierence...Naturally he was able to refine what some stupid kid came up with on his own.
Over the years, I have have bought more than a few cams...All sourced through Dwayne. I have directed many of my friends and family to use Dwayne's services with not one misfire...Not a problem ever!
Sometimes business comes down to... who you "want to get the money." All the names mentioned in this thread I'm sure are capable of getting you a cam that will work in your motor. Of all those names listed which ones post here on Moparts on a regular basis? Passing on their wealth of knowledge for free. Which ones can you call up on the telephone and have a conversation about YOUR car/combo and not feel rushed to get it all out in less than a minute? Then get advice you may not have known you needed with your cam purchace?
I just call Dwayne when I need a cam This ^^^^^^

I would not presume to recommend a cam (except for those small number I've used personally,).
I would feel comfortable preferring 1 of 2 or 3 as a choice.
I would definitely recco not using some mentioned ("is 270° @ .050" a good choice for my 318 904 3.23?").
If Dwayne did your heads, he's the first person to ask.

And why Isky is the best overall in MY world and all I use plus my roller has the most aggressive street-ish lobes while being easy on parts. 14+ years and changed springs twice and rebuilt the roller lifters once so far. Easy mid 9's and 6-teens so far and driven a good amount.......680-.660 276-281 on a 108 lsa w/97 degrees of overlap..... I too started with an Isky. A. RR735 grind with 1.55 rockers on a 528 alky motor with 440-1 heads. Went 8.77 with that cam at 153 mph at 1600 da and 3055 lbs. I had another more agressive cam cut and didn't see much if any improvement other than beating the snot out of my valvetrain. That rr735 was run with 340lbs on the seat. Ole Ed Iskenderian understood cam design way back in the day. Those shelf grinds are VERY good designs.
8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

I ended up ordering a cam from Dwayne Porter. Definately glad I did. He took the time to go through all my info and I feel very confident after spending 45 mn on the phone with him. Called Bullet cams 5 times in the last week after filling out the form and left many messages to call me back and still haven't talked with them. Thanks again Dwayne.

I ended up ordering a cam from Dwayne Porter. IMO your combo may be common in the last few years since the TF270 heads came out. Dwayne is familiar with it. So, I feel you made a good choice. Converter, gear, weight are variables other than engine. And user tolerance for valve springs is another. Tell us your combo and the cam lobes and/or specs.

What was your compression on that 511 and what did Dwayne give you for specs if you don’t mind sayin? 10.5:1. SFT 260/266@.050. nets a touch over .600 lift with 1.6 rockers. It’s drug my 69 roadrunner into the high 10’s with a six pack @ 4000#’s (with me). I’m building another one right now for a 69 dart. 512 10.5:1 440-1’s with the solid roller from Andy F’s 470. I’ll be curious how it performs. Cam for the one I’m building.

....I was asking for cam advice and intake/carb help. Its somewhat of a weird combo and my experience with something like that was minimal, having Race heads, street CR and a small solid roller not the best. Duane took the trouble in answering my posts and also spent time with me on pm's giving a cam recommendation with which lobes he thought would work with which springs, rockers etc. as I wanted to get some more out of what we had with the limit on CR which was a big restriction. Got to give it to him he was very helpful, where else can you get a good response like that on a forum from an expert in the field
