650 lifters & pushrods same as 750?

jseng1 · Feb 16, 2017

Are the 650 pushrods & lifters are the same as an Atlas (or Commando) 750.

Someone wants to use my cam kit in his 650 & I need to know if everything fits.

It could be that Atlas (& 650) pushrods are .080" longer because they used shorter valves and changed with Commandos.

thanks

Yes, 650 & 750 are the same, with both early and late pushrod and valve lengths. If he sticks with later/longer valves, should be no problem.

What length are the earlier valves & pushrods?

Earlier, before serial # 125871, the pushrods were 8.25" intake, 7.4" exhaust, valves were 3.933 for inlet, and 3.917 for exhaust.
