how much horsepower from my 318?

If an 86 318 with a 2bbl had 200HP, then the 210/220HP 318's from the past must of been measured with much bigger horses........... Cuz there is no comparison between the A318, and early LA 318's and an 86.....

And unless you know some kinda voodoo I don't, stock cam 318 doesn't gain much from a 4bbl and headers.... I've kinda done that a lot, sure, it makes a difference, but you can really feel 10HP............................

Think of it this way.....

If what you say is true, then a 86 318, with a 4bbl, and headers, would be 35HP shy of an old 340?

Nooooo wayyyyyy.
