Default Hot Rodding Methods

The two limiting factors to getting the engine to turn high rpm's are the ignition and the valve action. Says the ignition just is not firing the fixture completely above 5000rpm.


Then the valves 'crash' above 5000 rpm.So that is what needs to be improved.



Says the factory engine is good for 5000 RPM and the goal is to get it to turn about 7000 rpm.



This info is from the 1959 Hot Rod annual 'Hot Rodding Methods' article.


Once the engine can run at 7000 rpm then it is on to improving the breathing of the engine to burn more fuel and air mixture.


Which consists of 2 4bbls or 3 2bbl's, port work, bigger valves and such.



This is a darn good roadmap to building your engine for better acceleration and top speed.


This clear thinking in these books is first class!
