It's only a 15 hp hit from the 325 to the 350. The 350 is rated at 340 per NHRA.

325 HP is factored at 320, 350 Hp is factored at 340. That's 20.

Stock is still 325 in the Camaro. Only the Chevelle is rated at 320.

I'm looking at the chevelle combo to be more specific.

Here is a way to think about it.

325 hp - G/SA 3690 lbs 12.00 index
350 hp - F/SA 3740 lbs 11.85 index

So the camshaft would have to be worth about .2 , In a car that heavy, that would mean at least 30 hp net through the curve.
