Cam Specs. What do you think?
I will be dropping my car off monday for a custom spec cam and stal convertor install. My car currently has a cai, headers, full exhaust, and will get a cam and 3200 stall.
I want a big nasty cam. My local ls expert suggested that he custom spec me a cam- 234 / 242 - .629" / .620" 113 +4
What do you guys think this will produce? I dont want anything mild.
This is on an ls3 by the way

That camshaft will need a 3600 (or a little higher) stall. A lot of folks don't realize how badly performance can suffer if the engine combo & converter are not matched properly.
My personal opinion? That cam is a little on the large side and doesn't have quite enough split.
Recently we took in an 08 C6 from another shop with a 238/248 camshaft in it. The customer hated the driveability and lack of power down low. We removed that cam and the silly heavy Comp 921 valve springs. Reinstalled was one of our camshafts (224/234) and a set of PSI 1511ML Beehives. The result? The car picked up 40ft lbs of TQ across the board and make almost the same peak RWHP number. High rpm was MUCH more stable.
As soon as I have time to overlay the graphs I'll post them, but this same cam did 490/470 in a 5th gen Camaro.
This is a sound clip of what it sounds like. You don't need a "big nasty" cam to sound good...
And FWIW, I don't sell cams nor make profit on them. Our cams are cut by our vendor and paid for by the customer directly so this isn't a sales pitch. Just dropping some knowledge on what results we see every day. Hope this helps.
Cheers.

I agree without the supporting mods can actually be slower at the track, if I was going to run that cam I'd suggest a 4k stall and shifting at 7k as mentioned...average power is what gets you down the track faster and as Josh mentioned a smaller cam sometimes does that, which allows you can run a smaller stall in an auto and not shift have to shift as high

This is good advice. I don't know what has happened in the LS world, but there are a lot of bad ideas that have been followed by the masses and passed off as the "correct" way of doing it. Going large duration and retarding it a mile to make it clear is an odd way of doing things IMO

Race cars and street cars share what in common? I don't know why you made the thread you did if you already knew that your guy knows it all? You asked for opinions without actually wanting to hear any? Your car will be awesome, no matter what you read in this thread, I am sure you will love it.

I guess I'm too old fashioned. I actually like to match all the parts together to make a good combination and dyno numbers are not my #1 concern. *shrug*

I blame the internet marketing & hype for these issues. Certain vendors open a Comp catalog, point at some big nasty camshaft and say "Hey I'm gonna put a stupid nickname on that and sell it to everybody!" without any thought process behind it. Irks the **** outta me.

I do want to hear opinions...on what i asked for opinions on...the cam. Somehow my stall cam into question. This is a street car so no one in their right mind would but a 3800 or 4000 stall in a car they want to drive to work....
But yes i will love it either way. I was just hoping someone with a similar cam/setup would chime in. Thats what this forum is all about
