Patrick, how does the cam sound at idle? Anything like a T-Rex? I am planning on running AFR 205s and from the looks of it... a similar cam to your own. Just kind of curious as to if it sounds as mean as it looks on paper.

It sounds nothing like the T-Rex. It shouldn't. The T-Rex has around 25 degrees of overlap at .050". My cam has something like 5 degrees. It's much tamer. But it still has a great sound with an 850 rpm idle. The T-Rex would need to idle over 1000 rpm to sound like mine. Or said another way, my cam would need a 700 rpm idle to chop hard like a T-Rex.

is it bad to run a lower idle on a cam like yours? I really love the T-Rex sound, but love low end torque.

Idle speed is primarily a matter of taste. If you want a mean chop to the idle, you can turn down the idle speed. About the only thing bad that could happen might be that you will stall more when you let out the clutch. That's about it.

Hey Patrick, would you recommend the Cometic .027 MLS gasket for my PRC 2.5 5.3l heads and that LSK cam you spec'd me? It was 227/235 .639/646 110LSA +2

I'm just trying to tighten my quench and I really don't know that much about it. Thanks!

You can't go much tighter than a .040" gasket without risking piston to head contact. With the pistons .006-.007" out of the hole, a .027" gasket would put your quench around .020".

Nah, you don't need to go to that extreme...a .040" gasket is ideal for quench. The GM MLS gasket just leaves torque on the table.

Hmmmmmm. Perhaps that is why there is such a big spread between my rwhp and rwtq. I am running the GM MLS.

No. Your hp and torque issues are not quench related.

Set up a PayPal account and charge like, $1 per question.

Right before you do that though, I have a few questions...

Sharpe has the right idea! I'd definitely pay you for some advice! Nobody around here knows this much about the technical side of a motor. They just kind of piece stuff together and hope for the best. I just need to know specs on a cam and heads and anything else i might need to make the kind of power you are making. Let me know if you are interested in making a quick buck Patrick!

Will the stock lifters be okay with the increased lift? Will the increased lift shorten their life expectancy?

I use stock lifters with my car. They've gotten over 18k miles of running various LSK lobes. I've had 3 sets of heads but still the same stock lifters (59k miles and counting).

Patrick, I was referring to the non-nitrous pass. I figured out that the problem with the nitrous pass falling off was the plugs. The spray was blowing out my spark. Now back to the hp/tq split. Would it close the gap (currently at 50) between my peak tq and hp? If not, what would? I have not seen you really talk about ground in retard much on the cam. Why do it and how does it effect the cam? Mine is a 113 ICL with -2 retard ground in. Would this cause my huge split? If not, what?

Thanks in advance!
