We’ve got two exciting announcements for you guys and gals.

First, our new website is partially up and as a promotion we’re going to having a cam kit sale for both LS1’s and LT1’s. For information on the cams we carry just go to www.cmotorsports.com, then choose your engine (LT1/LT4/LS1/LS6) under the “Engine Store” tab. Once in the engine store, click on Camshaft Design and try not to go into cam overload. There are quite a few cams listed and cams can be quite confusing, so if you have any questions about which cam will work out best for you, please feel free to give us a call.

Second, we now have a valve spring kit with titanium retainers for LS1’s and LS6’s that offers substantial savings and improved performance over other valve springs and retainers currently offered. The springs that come in the kit are part #EX-616 which we’ve been running in some of our own cars for quite a while to make sure they are up our standards. In our Z06, we’re currently shifting at 7200rpm with this valve spring kit and a .591” lift cam and in our 2001 SS we’re running a .615” lift cam shifting at 7100rpm. The springs fit on the stock heads/seats without machining, just install and go!

The EX-616 springs setup at 135lbs at 1.800” installed height, open up to 360lbs at 1.200”, and don’t coil bind until 1.110”. We recommend a cam under .620” lift as that is what we’ve tested to, but the springs can handle a little more. The retainers, part #EX-122, are aircraft quality titanium and offer the ultimate in high-end valve train performance. For a few pictures of the EX-616 springs and EX-122 retainers, check out www.cmotorsports.com/615springpics.html
There is also a new set of springs that set up slightly lighter than the 616's, part #EX-615. They setup at 115lbs @ 1.800", and open up to 320Lbs @ .600" lift, with coil bind at 1.110". These springs are the springs to have for less agressive cams like the low lift Comp Cams offerings.

Here’s what is included in the cam kits:

LS1 Cam Kit Includes:
Comp Cams Custom Ground Camshaft
EX-616 Valve Springs
EX-122 Titanium Retainers

im the owner of the '01 ss. these new springs are awsome. as stated, shifting at 7100 rpm, these springs show no sign of giving up. i shift at about 6700 on the spray and still no signs what so ever. even with my 236/238 .600+ lift cam, the vavletrain isnt overly noisy. if youre looking for piece of mind in springs....these are it

mhoward

Man, I was just recovering from the transmission purchase, now you go and do this! You guys are going to make me go broke! But, I'll be broke and fast...

I'll be giving you a call tomorrow to order. Thanks again you guys for the great service with the transmission, it's going in tomorrow.

Is that the cam in your sig, you are talking about?

cmotorsports

There has been so much response to our springs and retainers that we have decided to do an introductory spring and retainer price.
Our Introductory package price for this shall be $199.95.
This includes the EX615 or the EX616 springs along with the EX122 Titanium retainers and locks.

You guys rule

ROB'S SS

update on the '01 ss. we just went 10.48 @ 129.3 with there new stage 2 cnc'd heads and the monster cam using these new springs.

mhoward

You guys were awesome to deal with on the transmission, so I'm going to get a cam from you too. I looked at the cams on your website, but there are SOOOO many. Is there any way that I can find out which one you guys think would work best in my setup? Should I email you the specs? Call? Which would work best?

My springs came in today. I have one head done, would be two heads done but someone at absolute forgot to send 4 of my intake valves back :p
Here is a few pics installed.




Hopefully if all goes well the new motor will be in this weekend.
Thanks, Seth, Andrew @ cmotorsports for the GREAT SERVICE

Those look really nice. How well did they fit?

frcefed98

iTrader: (16)

They fit perfectly. Just like Seth said they would. I definately didn't want to machine my heads for a spring rated for 600+ lift and I wanted to stay away from the rev duals so these fit the bill perfectly. And who doesn't like that price on them. Spending 300 bucks or more on springs and retainers is bullSh!t. I am glad cmotorsports came to the table with some decently price LS1 parts. I hope other vendors can do the same.
I posted up on the internal board but got no replies. I figured that some people on there would jump at the specs and price of these springs and retainers.

No flame intended whatsoever but you guys are either really really exceptionally happy with this company or you are getting paid to post this. Its like a damn commercial in this thread where the company says, "heres just a few of our satisfied customers."
Anyway, I'm very interested in this package. $200 is a great price for any springs with retainers and locks, even if they are shitty. Are they singles or duals?
frcefed98: why did you say that you wanted to stay away from the revs? I was going to purchase some on Monday from Thunder. They are $351 for the springs, retainers and seats. I have heard nothing but great things about them, especially over the CC918's that alot of people seem to go with. What are your reasons for this? Thanks, Mike.

Also: exactly how many miles have been tested individually on these cars? Are these springs good for 25k? I don't want to have to switch them out every year. I will be getting around a 230 .580 112 cam and shifting at 6600. Thanks again.

1) They are a single with a dampener.
2)Those springs will handle that cam all day.
Four of my firends locally are running those springs already with about 4 track visits already and 2-5 weeks of daily driving having already been put on them.
They have cams ranging from 228/228 .588 112lsa to 236/238 .602/.605 111lsa.
Flawless so far.
