to much dur. split for my liking. plus l92 heads are flowing good over .600 so why stop short and leave hp on the table? now if the dur was closer and got teh lift closer to .600 them you'd have a nicer setup

I am bit concerned with tuning the 106 LSA but otherwise should be fairly straightforward. Should know next weekend.

NoRice - from what I've read the the reverse split helps on the exh with the LS7 style heads. In an LS7 the lift will be slightly over .600" ...1.8 rockers.
I believe Katech's "Torquer" LS7 cam has a 20* reverse split.

How well would it work with the L92 heads?
TIA!

It works awesome in an LS7 I can tell you that. I put 300 miles on a Z06 with one breaking in the clutch and I'd say it's streetable but not nearly as good as our Torquer on the street. Final cal is being done now and I look forward to doing some more testing. It also sounds absolutely sick - like a race car. And I didn't exceed 4000rpm or 50% throttle due to clutch break-in.

[Thread Hijack]
Katech have you tried one of the LS7 Torquers in a L92 setup yet?
With 1.7 rockers the lift would drop to roughly .587/.608 correct?
That would probably be a decent cam for a ls2 shortblock with the l92 heads and l76 manifold without being to outragous.
It would probably put down about 450 to 460 rwhp with stock L92 heads and LT's (insay a gto or vette).
Any plans on putting out dual pattern cam's for the DOD motors
[/Thread Hijack]
How is the opening and closing rate on the Grand-Am cam. Its a fast open/fast close, fast open slow close, slow open slow close, or slow open fast close?
With the .575" max lift and no 1.8 rockers available for the L92 heads I'ld say the Grand-Am cam wouldn't show the best results with the L92/L76 setup. It will still probably lay down 500rwhp or more in a 402/408 but it wouldn't max out the air flow on the heads.
On the plus side that 106 LSA would sound sick through a set of headers and dump pipes. Probably wouldn't be street legal though (sound level would be wild).

Thats correct. We have not run a Torquer LS7 cam in an L92 yet. .580/.612 on a 1.7 RAR. No plans on releasing any DOD cams yet.

Katech.... for some reason I like those specs on a L92..... Do you have the graph on the LS7? Also what does the lift equal on a L92 head? If it had that same duration and .600-.615/.618-.635 ballpark on the same 110+4 ... I would be all over it for my setup! Sounds like a torque monster with that split!

edited... saw the post above... thanks for clarifying. I am looking for atleast .600 lift on the intake side and .620 on the exhaust (just for ***** and giggles) Still not a bad comparison. Do you have any plans to build an L92/408 combo?

236/249 in a 402/L92 The large split is very similar to the cam in my 402.
I'm putting a 236/249 112+2 in my 402/L92. Lift is 650/620. I'm using Manley Nextek dual springs.
I get the heads tommorow. The exhaust was cleaned up and they were shaved .020. SCR @ 10.8 and DCS @ 8.17.
I'm hoping it at least comes close to 500/500. I'll post the results when I get it dynoed.
