Cams for 318's

Great article, like how they broke down the steps of the add ons.

Was wondering about the compression ratio of their Recon 318 long block? Something like 8.2 to 8.5:1 compression ratio?

Something like that

Guessing by the looks of the original 318 truck exhaust manifold, that engine probably came out of a 1976 D100 Pickup with the same compression ratios listed above.

Was wondering what the final Results would have been had they started with a 1969 318 9.2:1 230 horsepower stock 2 bbl engine.

1 cr point suppose to gain 3-4% hp so like 290 hp

Stock 230 hp, with the addition of the cam, 4 bbl intake and 4 bbl carb an upgrade of 100 horsepower.

High doubt the 318 ever actually made 230 hp, look at the gross 2bbl 189 hp number before cam and 4bbl, not much difference between 318 specs over the years, 230 hp very generous rating.

Puts them at:
230 + 100 = 330 horsepower

Hmmm . . . Interesting Thought.
