Please look at the timing card that came with the cam. You will find the Federal Mogul / Speed Pro / Sealed Power part number on it. If that part number is CS118-R, then you bought the 30-30 cam copy distributed by Sealed Power.

Goodman, that EN-145 designation is Zip's part number. They are just the retail outlet, not the cam brand.

Not very. The early LT-1 cam (not to be confused with the late model LT1 cam) is a relatively mild grind and generates more vacuum at idle. That is a good thing for FI operation.
The biggest problem I have with the 30-30 cam is getting owners to use enough valve lash. The most popular settings now are the "magic" numbers found in internet chat rooms. These settings (.024"/.026") are way too tight for FI applications.
People seem to have forgotten why they call it the "30-30" cam. It really needs at least .030" lash to make enough vacuum signal to satisfy a stock Rochester injection at idle.

There it was
Had to peel off the sticker to verify the number.
Under the sticker I found CS-118R.
Guess this is the "30-30" copy then.
Difficult to see there was one sticker on top of the other, and I`m glad I kept the box by putting my old cam in it.
