Street driving / Highway runs / Drag Racing is no problem. it's road racing that's an issue with them.

I don't buy it. 600hp is 600hp worth of energy whether its a 4-cyl or 6 or 8. People use the same rad/fan for a 6-cyl as they do an 8-cyl or 4-cyl @ 600-800hp. 'Cars' that see constant duty (boats) high WOT%/time at high power (i.e. Z06 corvettes tracked) always need consideration beyond what the factory supplies(factory Z06 has issues just like anything else), but it has nothing to do with the number of cylinders or engine configuration or space (corvette is tighter than a 240 with a V8). It is more based on the fuel type used, on measures taken to cool the engine. For example water injection allows a limitless EGT reduction. Oil coolers, heat exchangers, its the same scene 240/corvette but the vette is more difficult. So I don't buy anyone saying 240 is impossible or "I couldn't do it with a 240". Nevermind all the creative endeavors somebody who fabricates regularly could pull off without going overboard or getting into a difficult job.
