Hey this sounds like a noob question, but I am baffled by the lack of info on the web.

Has anyone ran across a step by step guide for a CAM swap on the V? I don't care if it's a LS6 or LS2... but one for the V.

Yeah I realize a corvette forum somewhere might have one stuck in a closet somewhere... but for the amount of people that have done heads and cams here... where is the documentation?

Myself and some buddies wanted to tackle this one weekend and we were trying to estimate what we were getting ourselves into... not so much the motor, but taking the front end of the car off to get at the motor....

Anyone see anything? Got some pics? want to point me in the right direction?

I would be much obliged.

I've never seen one specific to the V.

LS1Howto has great write ups for an F-Body and a C5, which really isn't that much different:

I have the complete tech manuals that of course describes it, however the intial step is:

1) Remove engine

So i wouldn't be using that method.

I didn;t personally do my cam swap, but the shop that did mine, said it was a very easy swap. All you really need to do is pull out the radiator, and there is plenty of room in from of the engine to pull the cam out.

BTW, what cam are you planning on dropping in?

Good luck,

Chris

Yeah, the only thing that would be V specific would be taking off the nose. Anything engine related should be universal...

The radiator and fans can be pulled without removing the front bumper. Just FYI.

Livernois did a sweet article in a GMPP mag. They did a dyno before and after with only the CAM swap...with some sweet results. The CAM wasn't anything crazy... it was 218/220 @.5 w/ .570 lift and 114lobe.

I'm going down the FI route, and they livernois tech said if you were going to do that you should get a custom 110 lobe to help with overlap... so that's what I'm planning on. Thanks for those links I'll check em out.

I didn't see anything on youtube... but it's hard to wade through all the garbage out there, so I might have missed it

Oh yeah I should mention that the swap was done on an LS2, not an LS6.(thus the gain bcause of the cam differences between the ls2 and ls6) Here is the article link for your leasure reading :)

I don't know that much about this, but I do read a lot. Everything that I've read about cams for forced induction recommend LSA of 115-118 and an exhaust duration about 8 higher that the intake. LS6 cams ('02+) have a LSA of 118, which is one of the reasons a lot of people choose them when they're running boost.

Are you sure that this tech said 110?

Also, I may be completely wrong, but as an example, EPP's FI cam specs are:

232 / 240 .595 int .608 exh
Lobe Sep 115.0

I wonder what lobes that thing uses? That is a huge gain. My concern with that cam is that they are using uber agressive lobes, and even with premium dual springs, I'd bet that thing is going to eat valve springs. That is also a LOT of lift on the intake.

When doing a cam you really need to match it to your goals AND constraints. That does look like a daily driver, hgiher milleage type of cam. It would probabaly be good on a low milleage weekend warrior though.
