Making power out of the 318

Problem with picking a random power number is even 25 hp can change the whole cost of the engine and or driveline. To get that next step might need a whole different engine parts list and different drivetrain.

Eg. A 360 can easily get 275-375hp with a lot of stock parts and driveline, 400+ hp 360 almost everything starts to need or should be modded/upgraded.

very well said. there's no hard line in the sand on where the tipping point is, but the data available shows that 375/400 is fairly easily attainable with a 360 and not a ton of jack. where as those same numbers from a 318 are exponentially more expensive.

then comes the necessary upgrades to the supporting cast, because who cares if you make 400 horses and can't get 'em to the ground, or blow up parts, or can't take advantage of that power because of a soft converter and 2.76's

there's more to the whole picture than the horsepower number, and unfortunately that's the one thing most people get hung up on.
