There is no "best" cam....
It's all dependent on all the nifty gritty details of your setup, your engine, your goals...

ok u know what im talking about to get all the performance on gas...what one u have because i see u alot on here and u have a answer to everyone question so whatever cam u have is the one to get..........................high 5's low 6's in 1/8th is my goals

Just because I have a lit of knowledge, does not mean I have all the answers...

I went pretty good size on mine because I didn't really care about street performance as much...

Mine is a 248/252 .649/.646 112+4
And I'm spraying dual stage direct port, .020 first stage, .024 second stage for now...
The goal is to be at a .026 or .028 on both stages eventually...(that's 250-280 ish per stage....)

There comes a point where if you go too big, you waste a lot of nitrous for only a little return..

For the amount you're spraying SoundEngineer a wider split in exhaust duration along with a tighter ICL and wider lobe would advance the evo to a more heavy nitrous friendly set-up.

I would of expected a lot more exhaust split, a wider lobe somewhere in the 114-115 range and a 110-111 ICL. That really looks like a big N/A cam to me, but I am no Allan Futral and that is not meant as a slam.

You're on YB a lot and I'm sure you've seen what the heavy nitrous guys run.

For my 300 shot give or take I am going to be switching to a 239/255 115+5 cam on LSL and LXL lobes, maybe even XER/LSL lobes.

My lobe #'s are deceiving... They stay open at the top for a lot longer than the ones you just mentioned and are way more aggressive....

I will be changing to a different cam soon... This one was built for all motor and my old intake...
I plan on a cam better designed for my intake here in the future, but I'm working out some bugs and chassis things first with this cam...

What lobes?

I figured that looked like an all motor cam. Mine is even tighter on the lsa and icl, but it has more exhaust split.

hi guys

been thinking

how would you say a 248/254 615/622 114lsa 110ICL cam is for the bigger shots like 300-400

i have only done single plate so far .078jet itīs 200-225 shots size and it tooke well whith it.
planning on 300-350 later this summer

thanks

It will work yes, but there could be much improvement in your current cam timing for the bigger nitrous jet size you want to run. I would think something like 248/262 or 248/266 115lsa 110icl for 300-350 and for your current shot size your same 248 intake, but 248/258 or 248/262 LSL exhaust lobe with your 114 110icl.

For comp cams I like the LSL lobes and also LXL lobes for the intake, comp also has a another good hyd lobe called the HUC. XER are more aggressive and LSK are down right disgustingly nasty spit your pushrods and valvespring retainers out.

Custom futral lobes, made to make the lsk lobes look like wussy stuff.

My car is reasonably quiet, but my valvetrain sounds like the sewing machine of death is coming for your soul....

soundengineer

And its not valvetrain noise from improper setup... It's valves slamming shut with proper preload and proper geometry

LOL that "sounds" intimidating!!!

In my car I wouldn't be able to hear it though, exhaust is too loud!
