Im not positive but they look like they will work, going off of the fact that they are 115# seat pressure. Should be good to around .550 lift.

I agree. The 223/230 .565/.565 112 LSA cam would be a awesome cam. I would change the 112lsa to a 110 or 109 myself.

305 @ 1.200 bind 1.125

mean anything to you guys, I got them from a great performance shop here in town and are known around. Patterson Racing Inc. The have a bad *** lt1
At the stock LT1 install height (assuming you reuse all other LT1 hardware) that spring will be good for about .600" of lift, however the seated pressure will be too low for most aftermarket cams. The seated pressure of 115 is at a 1.7" installed height, the LT1 will be 1.78" so your seated pressure will be below 100 pounds which is less than the LT4 spring. This looks more like a flat tappet spring than a roller cam spring. You could shim the spring to give you more seated pressure, but depending on how much lift you go with you will have a problem with coil bind.

I remember seeing the specs for the Cadillac cam somewhere, its a small duration, high lift cam. No idea on the lobe design.
You will likely need a spring good to .600" lift. Might as well get some quality springs. You're valve train is an area you don't want to skimp on.

Any of these Valve springs will work good.

As you can see, I posted several times in that thread. That cam was cut for stock manifolds, and what not. Once you have headers, exhaust, and intake...you might as well go with a bigger cam to see the most gains. My car is lopey and far from stock sounding, not crazy sounding either, but I still get many races. Many guys find it hard to believe that I am cam-only. I run door to door with a lot of cars supposedly making more power than me.

I agree with getting a bigger cam like everybody else. The sleeper cams are kinda cool though but only if you don't plan for all the bolt ons or headwork.

Hot Cam springs will not work with either cam.

The least expensive spring I would use with the LE Sleeper cam would be a set of the Bullet VS 574 spring ($60 shipped). These have 130 lbs of seat pressure and 340 lbs open when set up at 1.750".

A better spring will be the Bullet VS 2700 Alpha Wire spring ($110 shipped). These have 145 lbs of seat pressure and 370 lbs of open pressure @ 1.750".

You will need to check with Larry at Speed Inc about what seat/open pressure you need with his cam but these springs might also work.

Both will work with stock retainers, locks and locators.

Just curious, do these springs use stock seats, retainers, and locks?
