building a mild Daily driver 318

AJ/FormS said

So if I understand this right, the ActionPlus, and a 600, and a 340type cam, dual exhaust,a valve job on stock teener heads, with the bowls mildly opened up, will make in the neighborhood of 310hp;more power than a stock, brand new 1970 340 engine?
What are you thinking? what did I miss?

With the headers as a plus, you would gain at least 80 horse power over a stock 318. I will tell ya what you missed, a 340 gross horsepower is more than 275, and that's not a secret. Now let me ask you this question: What did a factory 73 340 dartrun the 1/4 in from the factory? Get the numbers, and I will tell you I ran 14.40's at 96 mph with a non posi, 3.21 geared, 727 (stock w/stock converter), with the build mentioned above. Only I had a cast intake with TQ instead of the Action plus, and I had 360 smog heads, which to most folks here I hurt performance using the 360 on a stock block 318. Might I add, the 340 cam I used was a used cam with almost 100k on it, and the heads had much slop in the valve guides
