I have the 396/350 and it shows a lot of promise but I've been fighting electrical/fuel problems so I haven't made a good run this year.

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.

Re: 1969 396, 325 or 350 hp version???
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.
