Wide open question there. Almost like how many stars.
Ok I always like the F275 in near stock engines. And the 308 or bigger in the wild engines. But never undersell the F275 because it has tremendous duration a overlap for higher rpms. And when you add the ratio rockers, It really hauls the mail. If you don't go all out for trick heads, tillotson carb or big Mikuni . Check your PM
