Just curious but has anyone made a high compression M20 that could still run on 91 or 93 octane. With the right cam I think you could do 11.5:1 without detonation, especially since M20's have AL heads from the start. Domestic V8's are running compression that high with aluminum heads, cam and a good tune.
sure you can do a swap but sometimes its cool to make the best out of the obsolete, and poorly designed stock stuff!
