401m performance upgrades.
 
Looking for recipies for the 401 engines. Or ideas. I have the baseline data for the 305 -351 engines. And a lot of modification data. I run these on my engine performance software. The hard part was the initial data. But now that's done. So any real mods on the 401. I have some things cooked up. And am going to apply it to a 401. Just wondering. Soon as the 401 data is done I am going to post 305-351-401. All hp and torque curves. Plus all modifications I have seen.
