I have a cam Im goin install.. its a 234/242 .482/.496 113lsa on 1.5...

What do you think? What kind of RPM am I goin be seeing?
Prolly goin do some 1.6 so it'll be .514/.529.. Should be a fun cam.. It shouldnt hit to hard being a 113lsa, which will make for a great DD cam..

But what do you think of the RPM..

wow your lift is small. Barley bigger than a lil ole hotcam.

Where did you get that cam? Are you sure of those specs? What made you choose that particular one? I would do some more research and make a better selection.

I agree, do some more research, even though that cams lift is small, the dur. is steep, might not be too bad on a 113 though. I would try & find out who made it, & what all the specs are before installing it.

Sure you should do more research, but so should everybody else that told you to. The numbers you posted aren't near enough to get a good picture of the cam profile.

I'm not going to do like everyone else and tell you that the lift isn't enough, because for stock heads, it might be. Lift isn't everything, but someone with more detailed LT1 cylinder head knowledge can give you a better idea of what to expect.

Kinda reminds me of the asa cam for the ls1. They put out good numbers with big duration and small lift. Id like to see how that cam will do in the lt1 and it should be easier on valvesprings than a high lift cam.

He is going the right direction, Ask someone what are your cam specs and they always say I have a XXX lift cam. Yes lift is "Part" of the equation but the duration also determines what and where the power band is dictated. Agreed, if you have poor flowing heads then excessive lift will actually cause a loss in horsepower and reach its peak way soon. Lift and head flow should go hand in hand. We sent a set of heads to a shop to perform a head flow test, and at app 500 lift the heads flowed well, above that and flow suffered due to poor port design, (loss of velocity,tumble ect) so in this case the lower lift cam would produce better numbers. Make sense?

Yea every stock head ive had on the flowbench either goes flat or backs up at .500 due to the shortside. Most dont flow but about 220 to 225 stock. So if you have stock heads, that cam will be fine. Your just going to need some good valve springs with close to a 150 lbs on the seat and 350 open.

stock eliminator cam?

the bigger duration and low lift is going to make your lowend torque suffer a bit but will produce a bit more on the top end. 113 lsa is about as tight as you can get and still have a very easily tuned cam for ecu cars. At least with the obd1s, anything can be tuned but it seems once you get tighter than 112 the computer gets upset with the amount of vaccum being made.

It seems like on stock LT1 heads .525 lift is pushing it..

Is there any reason to go with that cam over something like a CC503? The lift is only .502"/.510" (w/ 1.5 rr's).

It's not all about the lift. I say get a cam in that lift range wit ha higher duration and lower LSA.. chop chop/?

"Hand in Hand" exactly..
This is a DD car and I want to make it as fun to drive as I can! 113 will make it drivable with no idling issue AND like he^^ said.. For stock heads, you dont really need to push the lift right?

I would run a smaller cam as far as duration with it being a daily driver. Also with a 6 speed any cam surge, bucking, etc is going to be much more apparent and annoying.

RoAdRaGe912

Surprised to see you in here. Hopefully we can make use of the appearance before this thread goes to crap.

The lsa in itself will not make the car "drivable with no idling issues," especially considering it's not that wide. With the large duration, you will have issues at lower rpms. I'd do some serious talking with a cam grinder as to what supporting mods you will need and what can be expected as far as drivability since it is a DD. My suggestion would be against that cam for a DD, but as I said a more knowledgable/experienced person can point you in the right direction (I'll guess different for DD).

So what your saying is a higer LSA such as my 113 over a 110 isnt goin make a difference in drivability??

As for the duration, wont the low lift make up for that?

RoAdRaGe912

I did not say that. I said that lsa BY ITSELF does not dictate drivability, ie just because a cam has a 113 lsa does not mean it will perform well at low rpms.

I'll be honest, I have no idea what kind of power this cam will make or what kind of behavior characteristics it will have. But it sounds like you yourself are not 100% sure either...so why not go with a time-tested and proven set up? LT1's have been around for a long time.

do you already have this cam? if so put it in there. then you can let us know how it worked with real world experience. i am learning new stuff everyday, but its difficult trying to figure out what is first hand knowledge and what is just internet bs.
