If you can't make a 318 run fast, maybe you shouldn't be giving advice.
So who in here races a 318? See post #27. All it takes is a pair of used 360 heads for $100, some machine work, a set of pistons, and a camshaft. All this nostalgia and bigger cubes don't mean a thing. When I was hot rodding, 318's and 360's were considered junk smog motors, and were scrapped. Not because they would not make power, but there were better motors with more potential to start with. A 68 318 is not the same as a 86 318, and on it goes. A low mileage LA or Magnum is very cheap to rebuild. Most will buy pistons and a cam anyway.
