302 heads are tiny runners. Very tiny. But will port out really well. I’ve read 240/250 on the intake. I hich makes for a nice street strip head. Remember, you can race anything without a single race part on or in the car!
Caveats to the 318 should not be ignored but also at the same time those that always say things like “Keep the cam little because it’s easy to over cam the little engine.” Are speaking the truth but also ignore or not pay attention to the build at hand.
The smaller the engine the more it takes to get it to perform. This often requires a bigger camshaft and the. To round out the package, more stall from the converter and more rear gear.
With this as a known, build accordingly!
