SLP,
are you going to make a LS1 big bore alum. short-block? I don't want to add extra weight to my car and I don't want to worry about switching the sensor wires from LS1 to the LS2.
Thanks

Anymore news or results?! It's been almost a week, there should be 10 new engine packages by now! Ha ha! Just kidding. I'm impressed that you've had enough time to be so kind and answer so many questions and still get work done. Keep up the good work.

I am considering ordering the L92 kit to top a LQ9 or LQ4 (depends on what I can find) that I want to but this fall. My question is about the cam choice: do you offer a cam similar to the Torquer V.2 from Texas-Speed (232/234 .595/.598 112) Would it have a comparable power band to the 51016? I wanted to go with a little more duration to get try to squeez a few more horses out of the engine, but I don't want to loose much mid-range (as the car will be a mainly auto-x/road course on the weekends and my DD). Has any work been done for the PTV clearance issues? It would be loverly if this was a bolt on and go Drivetrain will be a T56 with either 3.73s or 4.10s

Good Afternoon,

The 51016 Cam installed on a stock bottom end LS2 (stock pistons, stock crank,stock rods) with the milled SLP L92 Cylinder heads has too close piston to valve clearance to be used in combination together.

Exhaust = .082"
Intake = .043"

We will be working on a new cam that can be used with stock LS2 internals and the decked SLP L92 heads.

Also please find attached a dyno graph of our 402 with the 51016 cam and L92 heads. This specific graph is from a 2001 SS with SLP Headers, SS Lid, 160 Thermo, 3.42 Gears, and the stock SS cat-back. We have a handful of customers with the 51016 cam in their 402. They are extremely happy with its street manors and its performance throughout the RPM band.

Thanks
Hank

Hank,

Are you saying this is too close due to possible valve float or are you worried about airflow reversion affecting power. Thanks.

Good Morning,

I am saying that this is too close due to possible valve float.

Everyone have a great Memorial Day Weekend.

How much did you Mill off the SLP L92 Cylinder heads ? If it was left at the lower compression level and the 51016 Cam, would that provide adequate Valve to piston Clearance ? How much would that impact performance, but still allow a stock LS2 Piston or LQ9/4 Piston ?

We finished checking piston to valve clearance today with the 51016 Cam and the STOCK L92 Head (no decking)

Exhaust = .108" (good)
Intake = .073" (too close)

Thanks

My cam is a .581/.581 224/228 112 that is very close to your 51016. I just installed untouched L92's on my LS2 except I used a .040 cometic gasket. It looks like I may have some trouble on the exhaust side.

What do you think?

Hank I just bought an iron 402 with -2cc piston reliefs my cam size is 250/266 .597/.598 will your L92s work with this combo? thanks, Travis

Is the intake minimum .080" ? If so, what thickness gasket was used for the measurement ? Thanks ! This is great info from you.

I appologize for the slow response. Things got a bit busy here this week at SLP.

We used the stock GM MLS gasket on all of our piston to valve clearance checks. The min we will run is .090"

98C5LS2 - You have .010 less intake lift and .019 less exhaust lift then our 51016 cam. But you are using a .040 cometic gasket which is .015 less then then GM MLS so we can say it is a wash lift wise. .090" is the lowest we will run at SLP piston to valve clearance. This is in-case of valve float, over-rev, and missed shift. You will be under the .090" safe mark. If you want to go with this setup have your pistons flycut just a bit. It will be more time and some money now but might save you LOTS more time and money later.

Thanks
Hank

Hi Travis,

Are the piston tops flat? Are they a dome or a dish? How many CCs if either of the two?

With this info I can compare to the SLP 402 piston so that we can get an idea as we have checked here. But that would be the best I can do for you as it is impossible to know the P to V clearance without checking and mapping the cam.



Thanks
Hank

Is there anymore news on the LS2 configuration. Is there a new cam available yet? Not trying to be impatient but if it's relatively as good as the 402 combo it's hard to wait for it.
Thanks,
Russ

there has to be some new info about an LS2 based L92 head and cam package by now. Any thing small will do, I'd just like to know. I getting close to making a purchase and I'm still on the fence between a KB supercharger or a good cam, heads, intake package. I'd like to go NA but I'd like to have some solid numbers first.
Thanks!

I bought my L92 heads (now decked .030) and L76 intake for my stock LS2 bottom end before SLP had this package. Can the SLP cam for this combo be purchased separately?
