OK, after doing some further research and checking, I think that the #356 which is listed as a Speedway cam would be good running with 14-1 or 15-1 compression ratio and Methanol. Same basic conclusion for the #399 cam. Their really long duration numbers mean that they will work with the high compression pistons, but would give a lot less performance with a lower compression piston on gasoline. Main reason would be the effective compression ratio from the extended duration. The big lift on the exhaust lobe of the #356 cam I am not sure about yet. Seems like it would basically compensate for a poor exhaust port design or smaller exhaust valves or maybe a restrictive muffler system? Here in the USA we run a lot less Methanol because mainly the racing classes typically don't allow it. Some do but not all.
