Default dart big m chevy block

does this block take the 300 taller lifters with solid roller?also will this effect pushrod length or is the cup in the same spot with just a taller body?

Cup is in the same spot just taller body. A lot of people use them.

Have your machinist check the clearance on the lifter bores. Both my blocks had to have the lifter bores hone to the proper clearance. It can be catastrophic if the lifters stick . Needs about .0015 to .002

X3 but make sure the machinest knows what he is doing. Those lifter bore hones cut fast.

Well you would think so but two different machinist around here didnt check it and one had lifter seize on the dyno and hit valves.
