So I decided to bring the car back to Speed Inc and have them redyno tune the car using Speed Density and ditch the MAF. I didn't think it would pick up any power, as I can't see a 100MM pipe with a little LS7 cartridge sensor being a restriction..but it did. Picked up 9.75 rwhp and 7.61 ftlbs of torque. This is with a heavy LS7 clutch.
Thanks Speed Inc!

Great news, thanks for the update! All of our parts Speed Inc has assembled/tuned in the past have always done well.

The head will make power with most any camshaft. An ideal setup is our head + having us simply supply a grind for your specific application. If you feel like you want a grind like Jimmy used then we'd just provide a Comp LSL lobed cam - same level of aggressiveness with more potential to make power. Otherwise, we'd back down the scale of relative aggressiveness to one of the mild to moderate aggressiveness grinds we've run for years.

You'd certainly gain appreciably. We'd ask that you precisely measure your current p2v during disassembly however - most cam grinds are so inconsistent that we need a reference p2v measurement or the cam in hand if you want the maximum gain from head work while ensuring you retain adequate p2v.

Yup no MAF now. I haven't gotten the car back, but im sure it will drive good MAF less. Speed Incs tuner knows his stuff.

So a LSL lobed cam will make more power then a similar sized EPS lobed cam?

Says it will retain stock ptv clearance.

What injectors did you use? I'm going with the same cam in my car and not sure what size injectors I should use.

I used the GTP 36lbs injectors. On a LS1 car they flow about 40lbs or so which is more than enough.

I have been selling a 226/234 .600/.600 LS grind for the past 8 years that will make as much or more power, turn more RPM, and not be as aggressive as the cam Jimmy is running. As a bonus, it will actually be within 1deg since that is the tolerance we adhere to as opposed to Comp's stated +/- 2deg tolerance which often ends up being +/- 3-4deg.

much more info & cam list on the page I linked in the last post: http://www.advancedinduction.com/LSX...BilletCams.php

Depends, I explain why on the page I linked.

We have digitized the entire line of LSL lobes, and about half of the LSG/EPS lobes. The samples I have measured have essentially identical levels of aggressiveness when compared to the LSL's. At that point, the lobe with more area (LSL) wins since it gives you more power potential for the trade off you accept when running lobes at this level of aggressiveness. Though they can still be controlled with a good beehive spring, we generally don't run lobes at that level of aggressiveness unless someone specifically asks for it. You don't have to run lobes as aggressive as we're discussing to make power & retain street manners.

Depends - stock available p2v at ~11:1 with an OEM gm head gasket. That head will have significantly more available p2v if closer to stock chamber volume for guys who want to run larger grinds.

Hey AI: Any sales for labor day for some CNC work?

Could you PM me a price on the 243 216 CNC work up with a valve job? Heads are bare and don't need to be disassembled and brand new so no need for milling of the head surface and/or header surface.
