Big horsepower 318 builds

Agreed.
You don't see them because they don't exist in nature outside of the local cruise night and usually the only proof is the owner's mouth. Show me a 500hp 318 on a dyno and I'll point out the lack of any belt driven accessories, hood clearance limitations, and a real exhaust. Aside from pushing the power band up, I think the stroke and bore size is more of a limitation than we think in terms of having good heads "available".

Anyone who uses the dyno with dyno headers, ignition, carb and all that is wasting their time and money. If you are running a mechanical fuel pump you should be using that too, along with the alternator and water pump too.

With the heads available (the W2 has been around for decades and those heads will EASILY make 500 HP on a 318 or anything else) like the TF stuff that 500 HP is like oatmeal. It’s easy to do.
