i have a 12.0:1 compression 402ci w/ported l92 heads and port matched l76 intake. i've talked with all the sponcers i listed above and they all say something different. one says a cam like 238 256 610 595 114 would be the best and it needs that BIG split in dur- because of the big intake valve getting too much air in. another says 248 258 610 630 112(if you remember tpis 427ci,it was posted that anything lower then a 114 lob it lost power down low) one says cam timing is a must and another said they tried different cam timing and it made no real difference.one says no lower then a 114 lob and another told me they had better luck with the 110 111 lobs. they all say something different and now i have NO idea who to go with and i need a cam in a matter of weeks. the ls1 was so easy. what is the best way to cam these heads and intake right now? can any of the sponcers or anyone who can help,PLEASE.
thanks mike c.

You don't think you are going to get an agreement do you?

I'm going with a recommendation from Patrick G. Thunder is grinding it. My local shop is doing the L92 exhaust/dual springs. I'm basing everything on a SLP 402.

I'm going to try my 1 3/4 headers 1st, before I upgrade the exhaust.

I'm looking for driveability and over 480RWHP. Lot's of torque would be nice also.

I'll have it togeather in a few weeks and I will post the dyno charts.

If you've got a 3.90 rear end then you may enjoy the larger cam. The larger cam gave me a little better taction from the take off.

i went with a livernoise motorsport custom l92 grind, check their web site, they have a varity of l92 grinds and good custom support to help you chose a cam that best suits your combo

I saw on their site they have a Stage 2R. Seems it's the same cam I just put in my car.

Of the ones liste I would go with LG.

If it were my engine though, I would go with Bret Bauer. Just my opinion.

LG steered me away with their 500 dollar price tag for an l92 spec cam, seems a bit pricey in my book

[rant]Problem is, you'll be gambling your money by going with someone who may not have the proven experience with the L92 setups. Honestly, if you save $111 by going with a discounter and your torque is 20 lb ft down because the valve events were wrong, how good are you going to feel at that point? The reason why LG can charge more is you are not just paying for the cam, but for the hundreds of man-hours they've spent finding out which L92 cams make power and which ones don't. Go with someone who hasn't tried dozens of cam combinations and you could be taking a chance. Think of the cost of having to install another cam later because your bargain guy missed the mark.

Think about R&D when you see that $500 price tag. Sometimes paying more saves you big in the long run. [/rant off]

ok...first,my motor is not in the car yet. it will not be done and in the car ti'll mid april. second,i have 4.11 gears in a 12 bolt. third,my heads will be ported. fourth,they all have said(LG ,vengeance,tpis and t.s.p)they have spent many hrs finding out what cams work with the heads and intake. two sponsors said 114 lobs help lowend grunt ( tq) because the low velocity of the heads. also,keep the intake dur lower 232 because of the big intake valve(if it opens to long it pulls in too much air and is over kill) the exhause should be higher 248dur because the exhause is the weak area of these heads and needes to be pushed out. they also said cam timing is a must if you want it to perform right. they said grind up a ls1 style cam for the l92's and it will not give me the best performance at all. the other said the lca did'nt make much difference and the cam timing also did'nt make much of a difference either. he said a 248 256 112 would work fine. this is what i mean........they all say something different,so who has done the homework? i also see livernis motor sport cams are all on 113 114 lobs....is there some truth to the lca the others say?
PAT G- it sounds to me you like LG motorsports(so do i, i ran ALL thair x cams) but,have they done enough to get me the right cam for my set up. what do you think. i want the most i can get. all the shops say they have the answers..............now i need to know how these heads work and what cam will produce what i want,power in the 500+ range.
thanks all for any help. mike c. ps....who is bret bauer?

hi,

i would say go with a 230-245-115 .625 lift.

just my opinion

You should have taken my advice from the beginning, jack up those L92's and drive a set of TFS 225's under them

Just kidding Mike, good luck on your build, I happen to also think the big split from intake to exhaust with a wide LSA is the way to go, wonder what LG has?

That is close to what I am putting in my 427/L92. I went with a 230/242-115.

Not gambling, liverious motorsport are one of the many pioneers in the l92 tech, they have many hours of R&D with the l92 heads and which cams work best, heck they were even featured in gm high tech doing some R&D on L92 combos, but im not going to get into a pissing match with you Patrict, to each his own, i chose to spend my money wisely, shop around, compare specs, talk with my tuner about specs, etc, etc, not spending my money on snake oil and overpriced products is my main concern

thanks brian,i now wish i tried your heads. i got such a GREAT deal on this 402/l92 set up,i had to take it. as soon as i get the proper cam i'm sure it will be fine,but i'm not enjoying this right now.
