Pushrod Length With 02 LS6 Cam? Going to be installing this cam in a friends car soon. He is going to go with new chrome moly push rods which are available in 7.400 and 7.450 length at the same cost. Would the 7.450 length rods be better to use with the reduced base circle that the LS6 cam has or should he just order the stock length 7.400 rods? I believe the correct length is somewhere between the 7.400 and 7.450. I'm pretty sure custom length P/Rs would be more than the $5.75 that SDPC sells the ready made ones for. Also, are the Manley P/Rs that they sell a good brand to use. They seem to be the cheapest I can find.
Re: Pushrod Length With 02 LS6 Cam? I've seen this asked a few times. From what I've seen the 7.4's are a shade short and the 7.45's are a shade long. Most people would prefer to be on the slightly short side to be safe.

Re: Pushrod Length With 02 LS6 Cam? Hey SS... how does your car run with your Z06 cam? I just did a cam swap for a friend a few nights ago. I used the 7.4 pushrods. What happend when you used the 7.45? Did you start it up? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Re: Pushrod Length With 02 LS6 Cam? WS6-
I'm very pleased with the cam. Not a whole lot of difference until it hits 4000 RPM,(although it is a lot smoother) then it runs like a raped ape. I need to raise the rev limiter a few hundred R's and get some 4:10's to realize the full potential. The 7.45's just wouldn't allow the valves to close as quickly as stock. (No, I did not start the engine)

Re: Pushrod Length With 02 LS6 Cam? SS... another question for you. I installed a ZO6 cam in my friends car a while back and I drove it tonight. "He wanted me to check it out" I thought my car ran better than his did and mine is stock. at least SOTP feeling. You said that you can tell big difference when you get over 4000 rpm's. I didnt notice anything different with his. Just runs smooth the whole way through the power band. Do you think it needs programing? He has Autotap and the Preditor, maybe we can fiddle with them and make it run a little better? We also reset the PCM after the install if that makes a difference? Got any idea's? Where about are you in San Diego... Im in Granite Hills. Maybe we can compare the proformance between the two cars? Before we did the swap he had 335 HP and 345 TQ. Thanks for any help you have.

Re: Pushrod Length With 02 LS6 Cam? Ws6
My car definitely runs better than it was stock,it's quicker and faster. I had my cam installed when I had my engine rebuilt due to the dreaded oil consumption problem (1 qt. every 750 mi.) so it was completely out of the car. I have had no tuning done, it's a 2000 SS, stock manifolds (intake and exhaust, will change that soon) and stock heads (except the LS6 springs). I still need to raise the rev limiter about 500 rpm's. I'm in Poway.

Re: Pushrod Length With 02 LS6 Cam? been wanting to put an ls6 cam in my car. Can anybody tell me how good this cam will work in an A4 car <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
Thanks in advance

Re: Pushrod Length With 02 LS6 Cam? My stock 98 cam had a base circle of 1.552 diameter. I installed an 01 LS6 cam with a base circle of 1.520. That's .016 less lifter preload. I did experience more noise with the 01 cam. .050 longer rod would be too long. I now have a Comp Cam with a base circle of 1.540. This is .006 less lifter preload. I have no additional noise with this cam.

Re: Pushrod Length With 02 LS6 Cam? the base circle of the LS1 cam is 19.7mm
base circle of the ' 02 LS6 cam is 19.0 mm
0.7 mm difference is 0.027 "
so the ideal pushrod length is 7.427. They don't make them in that length though, so 7.40 would be ok

The LS6 cam will have no problems with the idle in an A4 or an M6 car since it has a high LSA.

Should I use the LS6 pushrods with my LS6 2002 cam or the LS1 pushrods?

Re: Pushrod Length With 02 LS6 Cam? check part # and see if factory LS1 and LS6 have same pushrods from the factory.You hear so much stuff on line.I am in the process of doing same swap.I am still not sure if I am going to use different pusrods or not.If I do it would be chromemolly for weight savings and am not worried about hardened ones if I over rev I would rather bend a pushrod then smack a valve to a piston.IMO
Re: Pushrod Length With 02 LS6 Cam? Ok, I'm going to stick to my LS1 pushrods then. Anyone want to buy some LS6 pushrods <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
