Cam Install Question

midnight340 said
I have light springs to check piston/valve clearance every 10* or so. Can’t remember how much is recommended to be safe.

Running the Dynamic Compr. formulas off Wallace Racing it shows advancing the cam builds more dynamic ratio and dynamic cranking up to about 4* advanced and after that the gains drop off.

If I'm correct this cam has a fairly short 48* overlap. With the installed ICL at 106 it shows 62*ICA with a dynamic compression ratio of 7.31 and dyn. cranking at 140.
With it 4* advanced I get dynamic compression of 7.53 and dyn. cranking at 146.

Are these just numbers? or something to take into consideration. I could lose some top end and not miss it. Are there any other down-sides to advancing it 4*????

If that was a hydraulic cam, I'd say she wants more compression ratio.
But a solid is rated different, so your dynamics and cylinder pressure should be a lil higher than the calculator shows; perhaps 5psi higher.
Yes there is a downside to over-advancing it; namely your effective overlap shrinks, and with it a smidgen of midrange power and a smidgen more absolute power.That cam wants to be in at 108, which is where I would put it to take advantage of the rest of that combo. But for your stated useage 106 will be just fine.
