Cam Gurus please look!!!

[1sehturk]

For the cam whizes here.. I have an 05 CC Z71 lifted with 35's 4:88 gears and 2800 Yank TC. I am about to swap in a .030 over LQ4 with 317's that have been cleaned up a little and .020 mill on them. I am using the stock truck intake and K&N CAI. My exhaust setup is Pacesetter long tubes custom mandrel bent y pipe with tiny little 6 in high flow cats and Magnaflow Cat Back. The cam that I have in the motor is a 224/220 581 581 on 116 reverse split (Old MTI grind). Cam wizards am I making a mistake? Looking for a torquey cam that will work well in the 370 ci LQ4 with the 2800 Converter in this tank.

Thanks in advance for opinions

Will it work. Yes...

Is it optimal, no by no means.

Something like a 224/228 with the same XER lobes would work better. On a 114+2 or 112+2, maybe....

So is my thinking that the the free flowing exhaust vs the stock intake setup being a little lopsided not correct? This was one of the factors that went into reasoning for this reverse split? What would be the advantage in the cam you spec'd vs what I have selected. Not being argumentative by any means I just want to understand. What is it about the cam that I selected that you feel might be undesirable? Power come in too late or ?

Your cam kinda looks like an sc cam. I agree there's power to be had with a 224 setup or along those lines.

These motors seem to thrive on a split cam. 224/228 healthy lift LSA 112. That 370 will eat a lot of cam before it shifts you too high in the power band. Also if you ever toss nitrous at that cam it will be loving it.

The stock intake does not restrict near as much as the exhaust. People waist tons of money on these fancy intakes when a cheap one will do just as good, there is not much power to be had when mildly modded.

Simply put you will have much more usable power under the curve, right where you need it. The split pattern verses a single or reverse split will broaden the powerband, sometimes lowering peak power but not always. Also if used correctly taking into consideration all the factors (IE ratio, intake manifold, FI, nitrous, exhaust. etc) you will not loose your peak power but gain low end/top end with a broadened powerband.

For instance the Hemi's work well with a 6-8 degree split since the intake valves substantially outflow the exhaust.

The cam you have will work but leaves a lot on the table.

I would think something along the lines of the 228r or split like 228/232 with decent lift on say 112 would do better than what you're looking at now. I'm not a guru by any means. Maybe garrison or farmtruc will chime in and give you some recomendations.

I would take a look at the LSL lobes from COMP. With those heads you could run something like the 219/227 @.050 610/614 on a 113lsa. This would give a nice wide powerband with strong low end and mid-range torque. Great for a heavier truck with bigger tires and still gives a choppy idle and good throttle response. JMO
