Default 1969 396, 325 or 350 hp version???

Is there any benefit to one or the other? Is the 350hp cam worth the 20HP hit?

Go ya one better. Is the cubic inches of 31 with a POS intake manifold worth 31 hp? 427/390 hp rated at 371.

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.

Relax!
If it was a great Manifold you would be rated at 390hp or more!

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

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.
