Stage 2 TSP 212/218 .550 low lift with GM Blue Springs in an 06 5.3L with 3.73 Idles fairly smooth. Barely has a hint that has a cam in it.

Heads are milled to 58cc.

@1FastBrick I think that the idle is extremely tune dependent. My 6.0 with the same cam has a pretty good lope.

I pulled 2 degrees of timing and bumped the Idle rpm a small bit.

I am sure if you add timing it will lope more. As it sits only a few people have done a double take and asked if it was modified.

Adding timing to reduce lope? Usually adding smooths it. Or are you just adding some to adjacent cells in order to get more of an rpm swing, (not increasing the whole cell range in the idle area)?

LSA makes a big difference, too. a 212/218 with 110° lopes more than a 114°
