I may not be doing a cam right away and only be going with 1.6 rr's for now. so the 918's or double springs will be ok with the stock cam?

 

what size cams do you guys think for stock bottom end, with heads and cam in mind? trying to run as fast as possiable 1/4 mile time. give specs

 

low mileage really has nothing to do with the age.i prefer to put more spring than what the cam calls for......

 

I would curious to see where a lot of the gains come from, are they an attribute of the new rockers or replacing worn out valve train components such as high mile valve springs, more then likely a combination of both. Which would explain why some cars pick up more then others, though I have never heard of any really ever breaking a stock spring, I imagine like any other spring in constant use after 10+ years, they must have some wear resulting in decreased power.

 

Im looking into this cam Ai 230 / 238 - .575/.575 - 110 LSA

You should check out "advance induction" they got some nice cam's

Yeah, good point. I wounder? it makes good sence.

What power gains are you expecting with this cam? wow that website is very user friendly when it comes to info I like how they lay all the cams out for you. It is like looking at steak dinners in front of your eyes.

 

i put NSA 1.6rr and all the supporting mods for that (guideplates, hardened pushrods, ect) and it was a nice little mod. nothing crazy. better top end. noticed little change on bottom end. i'd say it was a 5-10hp gain. now i just need my LT4 knock module to come in

 

is stock rocker arm length 1.5 or 1.6?

also, for you guys runnin the CC503 cam, what rockers you usin?


these any good?

stock is 1.5

 

On The Ls Cars I Think It's A Waste Of Money. Stock 1.7 Work Great! Lt1 Yes,, Upgrade,upgrade,upgrade

 

Just do it!!!

 

Do you think there is in really hp gain on a LS motor such as my own in the sig? I figured probabley not, just strength.

 

Yeah they have good info on there site. My HP goal with this cam is right around 365hp n/a but once I get ported heads and intake with retune around 390-400hp n/a.

 

That would be very nice man , do you still have Stock Bottom End?

 

Yeap, im still stock bottom end. Just have bolt-on's and removed some weight.

 

Thats awesome man very beautiful car too!

If you take the first cam and divide the lift by 1.5 and then times 1.6 you get the second one which is accordng to them an lt4 cam. The third part number is the lt4 "hot" cam with 1.5's and the fourth part number is the same cam with 1.6's

 

I see that some of you recommended 1.7's on stock cam . Would that require any valve cover modifications with the stock cam ? I have a 94 corvette by the way and heard the valve covers may have more clearance but not sure . Also with either 1.6's or 1.7's which springs would be good for stock cam and what else would be necessary for the swap ?

 

How does more lift change the sound??? At the end of this month, I'm installing some compcam 1.6 roller rockers. I did a cam swap a while back, and I don't know why, but I ended up buying 1.52 roller rockers instead of getting the 1.6

I'm running the 502 comp cam 218/224 durations, 495/503 lift 112 LS
