G'day Big Seven, "good things come to those that wait" or put a wanted post for good 2nd hand followers.
The 356 cam gives a lot better mid range and torque over the 344. The 357 is for rev heads like me for more top end.
io ic eo ec
344 = 24, 65, 60, 21.5
356 = 30, 70, 65, 25
357 = 42, 62, 67, 37
Cheers
