Cam Swap Questions

Am I correct that you can swap cams in an LS3 without removing the front fascia? Am I also correct that the labor for the cam shop in an experienced shop should be between 4 and 6 hours?

Yes you can do it with out removing the fascia, I would say yes they should, if they've done it a few times

No it can not be done in 4-6 hours.... Thats probably what this forum will tell you... But they also say headers takes 2 hours.

The shop I am going to told me 3 days for an LS3 conversion, cam swap, install new torque converter, before and after dyno pulls.

If it's a straight cam swap in an experienced shop, 4-6 is about right. If your going to change the oil pump, upgrade the chain, upgrade the rocker arms, etc, which you should if not already done, the time will go up. My shop charged 14 hours to do the cam and all the other things that go with it, headers, full exhaust, cutouts and tune.

Guys, I'm just talking about a cam swap. The lifters, valve springs, trunion upgrade, oil pump, head work has already been done with the present cam. I'm talking about just pulling this cam and going back in with a VVT cam. No associated parts except the VVT sprocket and cover.

And for those that have said no, without giving any details and estimate might as well have saved their breath. Worthless IMHO.

Being that you can pull the facia off in 15 minutes. I would pull it just to be safe and easy access to everything else. I don't see any reason why just doing a cam swap not messing around with the pump/timing chain it can't be done in 4 to 6 hours. In a very well-prepared shop that has past experience with aCamaro.
One thing I'm curious about is I never went back to the VVT cam. Can the lifters that are in their handle that VVT camshaft?

From what I've been led to believe the VVT has nothing to do with the lifters whatsoever. The different lifters in the L99 are there for AFM/DOD. Those lifters, and all their associated parts (among other items) were swapped out when my LS3 conversion was done for my present cam. My understanding is that to go back to VVT I just need a VVT timing cover, sprocket, solenoid, VVT cam, wiring pigtail, special center bolt and maybe a few other minor items. Unfortunately, I didn't get those items returned when the LS3 conversion was done, and it has been too long to even hope they are still laying around at the shop that did the conversion.

I'm just trying to put together a ballpark cost for labor hours (I have a ballpark cost for parts) in order to make a decision as to whether to go back to VVT. I'm looking for more torque in the lower RPM range, and understand VVT will get me some.

My bad for not explaining this in my OP.

You are right VVT has nothing to the lifters. Yes your parts list looks right to convert back to VVT with that being said 4-6 hours looks about right for the labor. And no you do not have to pull the front fascia!

any reason why you want to convert back to VVT?

On these cars...good headers do only take 2 hours. I did mine on a lift on my buddies lift at his house. Took an hour and 45 minutes. Unbolted the catback and supported it on a stand, unbolted the 2 cats, pulled the plug wires and unbolted the manifolds...that was 10 minutes...reached up and screwed in header studs from ARP, hung the gaskets and headers/cats...bolted everything up, put the plug wires back on...torqued everything...done.

Also did my cam swap without removing the front fascia. But anyone doing that in 6 hours is probably hacking the car.

What don't you understand? As mentioned is Post #9 the torque curve on present cam is anemic at lower RPMs.

Completely agree. Possibly if it was a cam only, but on all of our kits we upgrade the chain, the oil pump, valve springs, pushrods.....it isn't just a cam swap.

The radiator and fans come out, but no the fascia is not removed.

There is zero gain to be had by pulling the front fascia off of these cars to replace the cam. Zero. 15 minutes wasted and a potential for scratching when off of the car. No thank you.

OP, in my garage, using all hand tools with no air, it took me about 10 hours to install valve springs, trunnion upgrade, oil pump, cam, gear and chain. An experienced shop with better tools should be able to do it in 6-8 hours.

You got the wrong cam in there then if you think switching back to VVT is a smart move.
