beachcomber said:Oh boy ... along with my recent good health news - I now have my Glemseck donor engine [ blower / nitrous ] AND my twin plug head ! I also collected a spare exhaust camshaft to be modified [ rev counter drive cut off ] to use on the intake position. This gives more lift without affecting the overlap. Cheap horsepower !
beachcomber said:Uncharted territory :.................. what do we think guys ?
The second plug .... short reach plug so the threads / body on the inside [ nearest crown ] are level with the opening where it enters combustion chamber and remove / smooth out the threads on the other side .... or - what ?? ???
