273 302 318 340 build

I did mean the 340 factory intake. It is a nice dual plane that in the end will only breath through the 318 ports. I was thinking just a quick easy hop up to get you by without tearing the 273 apart or taking the good 318 down too far. If you want to take everything apart and take the best parts and do some quality machine work, I'd have a different answer... lap the valves, if nothing else to check the seal. Definitely keep the 3.23 gears for the street.
