Ls2 cam

[malbright]

So I recently purchased a stroked LS2. 402, eagle crank 4.0, eagle rods 6.125, arias pistons 3.997, patriot cnc ported heads with 2.05 & 1.6 valves.

The cam is a comp cam .612 intake .612 exhaust, lobe separation is 113, with duration of 248 intake and 252 exhaust @ .050.

Is this small? Appropriate? What I'm not sure is if stroked motors, or LS motors make a difference. I guess I thought the duration would have been a bit more but again not sure if the package makes a difference.

I am running 3.89 rear gear, T56 mag trans (gear combo not decided).



Im hoping to be educated in how it all ties together and how decent this cam is or is not?

Thanks in advance.

What is the powerband your are looking for, compression of the motor, power adder or not, what intake manifold, and what is the use of the car ie; street, street/strip, autocross, road race, cruising? Does the cam have any advance ground in it?

Also do you have the grind number of the cam. I couldn't find any of those lobe profiles in the comp lobe catalog.

its def not small.... Is the car primarily street driven or will it be used more for track use?

I don't know the powerband. The compression is 11:1, no power adder, and the intake is a GM performance part top mount throttle body. The car will be street driven as well as autocross and light road course. The cam is a custom grind for cbm Motorsports who built the motor.

I had almost that exact cam (mine was the Texas Speed "giant") in my TA with a 408 and ported LS2 heads. I had a Vic jr intake. I drove mine on the street all of the time and drag raced it (nitrous car). With the tight 3600 stall nitrous converter and 3.73's it would destroy the tires from a roll on the street... It is a pretty big cam, even for a stroker, but has a ton of mid range and top end power.

I would say that cam is a little large for what it looks like you might be using the motor for. Like previously stated that is more of a drag race/aggressive street cam. I would look to drop some duration for a road race cam, something closer to a mid 230s low 240s duration cam might work a little better.
