I have a 05’ vette and it is auto which means it has the 4L65E transmission. I have a full exhaust set up on the way already & looking to switch out my stock heads for ls3 heads along with forged ls3 intake Manifold. I also want to go for a cam kit that my tranny can handle without a stall for now until I can afford a Yank stall later on. Any suggestions on what kind of cam kit to go with ?

 

Moved to C6 Tech.

 

Not sure what you mean by forged intake manifold, but Gwatney does a really good port and rod mod job on stock LS3 intake manifolds. Good bunch of guys there too. They don't mind answering the phone and I've always gotten someone business like and knowledgeable on the other end.

I'd get Pat G to spec you a cam with your particular Vette and your particular needs in mind. All he's selling is cam specs. He's not going to try to sell you the cam he has in stock or the cam that he ordered too many of. He doesn't sell cams. It might be the best 25-40 bucks you'll spend on your Vette. Here's a link to his service CUSTOM CAMSHAFTS | patgtuning .

If your LS3 heads need work, Tx Speed can CNC port, do a competition valve job, mill to your spec, clean and assemble with your valve spring of choice for a very reasonably amount of money. I used them several years ago and it was around $700. I believe it's more than that now but still not huge $'s for what you get. You pretty much get back an "as new" set of CNC ported heads. I'd bet Pat G can tell you how much milling of the heads is safe with one of his cams also.

 

There is no good compromise IMO. When you do decide to upgrade to a higher stall performance converter you will want to get a cam to match, but in the mean time the GPI Stage 1 is a fantastic cam for stock converter and rear end (unless you have SUPER TALL gears!) It is a little aggressive on lift so you would need a good double spring and appropriate retainer. I run their GPI stage 4 NFC in my stock bottom end LS3 (gmpp CNC ported heads, Cadillac Racing lifters, Katech ported 90mm TB, Holley Sniper intake, 60 lb injector, 4500-4600 Circle D billet converter, 3.91 rear end) and it pulls to 7500 rpm

Give them a call and they can spec what you need. (2005 is an LS2 cathedral port motor so you might want something with less duration split than a rec port grind however)

BTR stage1 is easy on the converter.

 

I found Precision were really helpful getting my convertor for my 05 built in a rush to catch a container being shipped to the uk. They had it built and ready to go the SAME DAY! 2800 stall for a LS2 404 stroker, triple billet clutch

 

I've got an 05 6 speed that I did a LS3 topend on.

Like Old Motorhead (whom I talked to when i was planning - thanks Rodney) I had Texas Speed port and mill the heads and Gwatney ported both my original throttle body and an OEM LS3 intake. Car has long tube headers and NPP exhaust. Lots of other goodies including C6 Z06 brakes.

LS3 heads have bigger combustion chamber so milling is critical to retain compression ratio.

You will want to replace the stock LS2 MAF sensor with a blade style LS3 model.

I went with Cam Motion Titan 2 - 222/230 @ 113 and Comp 1.8 steel roller rockers. This cam is a little large for stock converter. I also considered their LS3 Stage 3 Camshaft (220/230-117+4) mild performance cam. https://cammotion.com/camshafts/ls3-...220-230-117-4/ this would work for a stock converter.

Call CM and ask for Bobby, the man is an absolute genius about cams and especially pistion to valve clearance when milling heads and bigger cams.

No disrespect to Pat G, I paid for his cam recommendation, but Bobby was extremely helpfull on my P2V issues as I was using the 1.8 rockers and milling head with a thinner gasket. Bobby will also do custom cam recommendations.

I had electrical gremlins until I put in LS3 AC Delco spark plugs. The car did not like aftermarket plugs.

A custom tune is mandatory. Have recommendation there also: https://www.corvetteforum.com/forums...vette-air.html

PM me if you want to talk.

 

Do the converter FIRST. Then do the cam. If you do a small cam so you can use the stock converter, you won’t like the cam after you do a real converter (Yank SS3600).

 

Thanks to everyone for the info that was provided , very helpful ! I’m looking into either btr stage 1 or cammotions stage 3 ls3 cam as soon as I figure out the issue on why my battery isn’t holding up any charge. Any recommendations what to check on this one ? I already replaced battery and alternator although the battery was jump started several times while I had the (non-working) alternator in. It was also jump started with new alternator in. Is it a good idea to grab a new one again since I do have warranty ?

 

When I got it running it would jump up and down from 13.4v-13.9v.

 

How is the drive ability with a 4600 stall and 3.91 rear end ? I would like to daily mine or atleast drive it every other day and have fun with it. I currently have 3.15 rear end so that will be an upgrade to be considered as well !

 

Personally, I think a 3600 stall is a bit much on the street. But, to each their own. I went with a Yank 3200 on my C5, never a problem in 60,000 miles/16 years (where's that piece of wood to knock on??!!!). I was going to keep the LS1, and build it. Changed my mind and went with a built LS7 instead. I feel like I could've gone with a bit lower stall, seeing I went with the bigger motor. Regardless of stall speed, it's my personal opinion you can't get a better converter than a Yank. If it's good enough for Lingenfelter, it's good enough for me.......
