Am I an idiot for even thinking this will work with my bolt on LS1 and stock heads ? The lsa is on a 107 or so, that is gonna be a bitch to idle.....

IS your car a M6 or A4? Do you have a stall if it is an auto?

greekss

an m6.... i wouldnt run this if i had an auto, actually im even iffy running this cam in an M6, i figure makin it idle will suck

one thing is for sure, it would lope like nothing else lol

not sure u wanna do that if u drive the car like anywhere lol, i believe u may be better off both at the track and on the street with a magic stick, trex, or g5x3 or what not. definetly need mad gearing with any of these cams to stop cam surge and be in the power band.

honestly, id try something like a 233/239 from tsp, a f13 or f14 from futral... id keep it in the 230's if this is a streetable car.. all depends on you tho.

do a search, the grand am cam seems more suited to track racing. There's a few guys that run em, and i would love to see em mated up with the gmpp cnc ls6 heads. hopefully somebody can chime in on the performance on a daily driver, however i dont think it's quite what you're looking for.

my buddy's running this cam in his a4, daily driven. hopefully he sees this thread to let you know more about it.

Not a good daily driver cam. Very nasty idle. Tuned a few C5's with GMPP CNC heads for Grand Am Cup racing. Can't disclose HP numbers.

Binks is/was running one w/ an m6. another guy, dont know if its the same as who white00ws6 is refering too has the cam in an a4.

both said tuning was a nightmare. whats funny though is the Grand Am Cam, isnt even "big" anymore. you can have it cut on a 110 and im sure 112lsa if you want. talk to Louis. though unless you need to be making power at 7k+ i'd look elsewhere.

I can cut that cam on any LSA yall want.

Typical cars with the cup cam, and GMPP LS6 heads make 440-450.

Peak torque is 48-4900, peak hp is 6600 with a stockintake manifold, but it doesnt fall off the hp curve past 7k.

That cam would be more "friendly" with more displacement.

yeah i have this cam. running it on an A4, stock stall, stock motor, daily driver. tunning it's idle isn't that bad, just gotta know how to use Ls1edit, that was my problem in earlier days when this cam first came out. it's not all that bad for a daily drive , it's all about the tune. this cam is no sissy cam when it come to making power across a broad but peaky powerband . she dead around idle to just under 2k, but more get up and go then your flooring your honda off the line. around 2-2500 she really hit in hard and makes torq all the way up to 44-4900, then you horsepower hits in 5k and cares you well past the red zone, never feels like it leaves. she a peaky cam when she hits her power mark she hits them hard and cares it out. you can feel the transition from torq to hp. the only thing is gas mileage probably on average 15mpg and i live in the city traffic driving,, as far as everything else i've gotten her to idle in gear without dying, got her to start with out needing to push on the accelerator, idles good and smooth all on an A4

what about piston to valve clearance with stock heads? or with aftermarket heads?

DVCrazyCamTAWs6

its pretty tight. your gonna want the best spring you can buy that can handle high reving, i got the manely, or plan on kissing ur piston of then that it does requires valve reliefs, but will still work without

That cam was designed to be run with the GMPP heads which uses the stock 02+ LS-6 springs and valves. The light weight valves and beehive springs are well suited to the high reving Grand Am cam.

Jub Jub,, I have searched a little, but could you guide me where could I find more information on these heads and camshaft?

jub jub

The heads:

88958622 Cylinder Head SBC - LS-6 Gen 3 Aluminum Racing. This CNC ported head is for Corvette showroom stock racing. With this cylinder head and the ASA camshaft, Gen 3 engines can approach 500 horsepower in racing applications. This cylinder head includes production LS6 valve springs and valves. These ported heads are race only. Not for street usage.

The cam:

88958606 Roller Camshaft “Gen 3” Showroom Stock Design --
This hydraulic roller camshaft for RPO LS1 or LS6 was designed for showroom stock road racing. It requires the use of 2002 and later LS6 hollow stem intake valves P/N 12565311, hollow stem - sodium filled exhaust valves P/N 12565312, and valve springs P/N 125565313. It features .570” intake and exhaust lift, 251 degree exhaust duration at .050” and 239 degree intake duration at .050”.
Technical Notes:
• Center line of intake lobe means M.O.P. or maximum open point, determined across nose of lobe.
• Lobe flank is not symmetrical - for best torque set intake to TDC@105 degree and for best poer set intake to TDC@106.5 degree.
• Cam timing @ 0.050” tappet lift (timed @106 degrees intake to TDC)
• Exhaust opens @ 51 degrees and closes @ 20 degrees with duration at 251.
• Intake opens @ 12 degrees and closes @ 47 degrees with duration at 239.

As a side note, someone that worked for Lingenfelter, did the R&D for these heads, so you know they flow pretty well.

I read an old SAE paper about the engine build up. This was when they were using the asa cam (226/236 525 110). For headers they used 1 3/4" stepped to 1 7/8" with a 3.5" collector.

The world cup cam with the edelbrock headers might be a strong set up. I would like to try it but the cam is too expensive for what it is.

Are you still using this cam on your new motor? And how long did you have this cam for? I think I saw and raced you a couple times (if thats you). your car was untuned and you had a broken headlight motor right? anyways just asking if you still had the cam in the car or if your thinking of selling ...just asking...Thanks

PS. your president has the SALEEN right?

I'm guessing somewhere around 625 @ the wheels. Close? Or you that sworn to secrecy?

ok, maybe not that much, but i'm still gonna say 550~600 to the ground, considering they put air restrictors in the cars to slow them down.

jub jub

The Grand Am cars, if adhearing to the rules are around 450-500 at the wheels.
