Max effort cam for not DD
Brian is right, you will never pass emissions using a cam with that much duration and overlap, like the cams listed above me.. but I think you can work your way around the emissions test. Just find the dealership or muffler shop that offers the most lax test, and bring them a six pack or something.....lol.
Well you're asking for a lot here. First off, there's no MAX EFFORT cam that is not going to have a lope. Second, the largest cam that I know of to have passed emissions would be a 224 cam and that's no where near MAX EFFORT. Both the cams you listed above with the G5X4 and the F14 both have lope to them. The combination you're seeking is just not really possible. You're MAX EFFORT would be the biggest cam you can run and pass emissions and not have a large lope to it would be the 224 cams.
I can deal with the PT4000 stall w/3:42 gears and the constant rocks being thrown into the wheel wells from the Huge drag radials .
If i need a cam that thumps like the TRex to get to my goal of running bottom 11's-to high 10's all motor then ok.
I was just looking to find out if a high duration/high lift cam could have great top end pull and not have a real tight LSA too. I have run this car for about 3-4 years now with a very loose convertor and wished for the top end pull to match the quickness off the line.
We bought my wife a 06 GTO A4 and have a 04 GSXR 1000 in the garage too now,so i am ready to pull my car apart and go for "Max effort"
flamingo-flaps- Thank you for the research. It seems to be hit or miss as far as location and emissions goes.
Lots of great input from everyone,thank you.

Like everyone has said before, max effort will pretty much eliminate stealthiness, but the MS4 is on a 111.5 lsa so it will idle a lil less lopey than the trex, but the trex and the MS4 both pull amazingly hard on the top end, with a lil low end loss, but with a 4000 stall that will be moot. But hey who needs stealth when you car's idle will shake the import next to you apart! If anything hit up Patrick G for a custom spec cam he will take care of ya!
Your all thinking in the wrong direction . For what he wants Id go with a smaller duration , high lsa and maybe with it installed retarded . Kind of like the MTI Stealth cam . A cam like this will want a good bump in compression .
Maybe even a reverse split to make the ivc later and have big duration cam rpm .
230/224 .612/.609 117lsa -1 something like that . You would have a difficult time hearing any cam lope .

max effort = high rpm operating range = alot of overlap = rowdy idle
You're also limited with the springs you're using. The vindicator, MS4, etc are all big cams for stock cube cars, but I don't know if I would call them "max effort". Something like a 264/276 on a 108 with between .750 and .800 lift with the heads to support it would be max effort. It would probably not idle any lower than 1500 though. RPM range would be 4500-8500 ish.

So to run low 11's w/ full weight my best bet is.
"Vindicator
MS3
G5X3
MS4
G5X4
TREX "
Is there any cam that is gonna work for both performance and still be able to cruise on the "Power Tour".
We took my car last year and we plan on going again this year.
I may be asking for too much, low 11's,full weight & still driveable on the highway w/ 3:42 gears.

Crane has a 266/276 .624/.624 114+4 if you wanna try that. I wouldn't recommend that personally, but if you are trying to get into the 9's N/A with a 346 on a budget, good luck. 9's N/A takes alot of motor and money to get there. Some of the BEST heads, sheetmetal intake, compression, solid roller, killer LW short block assembly and tons of money will get you there.
I've lived in Davidson, Rutherford, and Sumner counties. For 1996 and up OBDII vehichles, they do a visual inspection for cats. They then test the fuel cap for a proper seal and plug into the vehichles computer and check for any codes. As long as the computer says everything is okay, you can pass emmissons. That's the benefit of OBDII. You can run any size cam you want and as long as the computer says everything is good, they will pass you. I have interchangeable cats and straight pipes. I just have to put the cats on before I do the emissions check.

. How often do you have to be tested,is it every year for tags like when i lived in Florida?
JPH- i am not looking for 9's all motor,that is not possible w/ my budget.
Now that is great to hear,thank you. I can go the route of swapping in cats in my y-pipe too then .

My car already went 10.3x's @ 132+ n/a with stock suspension/weight.
I want to stay hydraulic roller. The cam I have now is 114 240's .600. Looking to go bigger.
Any recommendations?
I would never recommend either of those cams to someone if they were asking for a set up to pass emissions, I would prob suggest a 224 cam for that. But when someone says they want a MAX effort set up all thought of emissions pretty much go out the door.
