Basic 318 Mods
1. Recurved distributor, properly set up vacuum advance.
2. Headers and decent exhaust. This is the true zero compromise mod. Even the most mild setup will benefit from headers. And contrary to old school train of thought, long tube headers will ADD low/mid range torque.
3. Cam. A modern, MILD cam, will give you more power above 4000 rpm, without sacrificing much on the bottom.
4. Good intake and carb. Just a modern dual plane and something like a Holley 650.
5. Heads. Lots of info and opinions on this one. But just about any 360 heads, or if you want to get fancy you can adapt the magnum heads, it's not a big change.
Do 1-4 and you should be able to easily break 300 hp, without destroying the streetable manners of the vehicle. Do no. 5 and it's probably around 350. Still very mild and street friendly.
I'm going to copy this post and repaste it from now on when the 318 with mild mods question pops up. :lol:
