this is truth... i would've answered this last night when i came home at 430am but was too tired haha.

hmmm, thinking about it... didn't the smog laws first comeinto place around 1968? i thought it was car's and engine pre-68? more than likely you're correct though.

What do you guys think?

I think the Honda F20c is one of the best (if not, the best) engines of all time. For it's size, it makes an incredible amount of power (nearly 125hp/L), has a 9000 redline, and will last for 500,000 miles (more, I'm sure, but no F20c has reached that yet) with nothing more than oil changes.

Some of you guys will probably think that I'm crazy, but I know Jason has to agree (at least partly) with me on this one lol.
i agree 100%... F20C is probably one of the greatest NA engines EVER MADE (piston powered).

with that said....

Ive always loved the Chevy dz302 as well, a small block v8 that would rev past 7000rpm from the factory in 1967 is damn cool.
i also agree here... the 20B 3-rotor. 2L... makes about 250hp. so about the same as the F20C BUT i think the 20B didn't come naturally aspirated did it? you had to physically remove the turbos to convert it to NA. i'm sure i'm wrong but i've never claimed to be all knowing. haha
