No i meant exactly what i said.. A 6m is a 5m with a 7m crank and different timing gear.. The crank in a 7m is just that a 7m crank.Yes it is shared by the 6m but the 6m has the 5m head.. The blocks on the M series motors all share the same blocks regadless of displacment.. Even the 2.0 2m made in 1965..No difference.. All that toyota did was enlarge the bore and stroke over the years aswell as head design .. Sure you could say that the 7m had a 6m crank in it but they are the same through and through.. Just the heads were changed along with the pistons because the 5&6m's had 2 valve releifs and the 7m's use 4 valve releifs.. Try to run a 5m head on 7m pistons and your going to bend every valve, same goes for the 7m.. Ive been here for awhile i broke my laptop and havent been on for a smooth minute but ill be checking in more often now.. I have learned so much about these cars inside and out that i get a hard on seeing one driving down the road and cry when there is one in the salvage yard..
