Hi Learned Brethren
I’m doing some work in building up an engine from a selection of blocks, cranks and heads which I have collected over the years. A bit of skimming will be needed on most of the heads and I have good data regarding minimum dimension limits on these.
But can anyone give me a guide to the limits for the block faces? One I have has been welded at some point and another has damage, maybe even from a hacksaw blade through a stud... God knows what the head must have looked like! I’m guessing the dimension would be from the crank main journal (without shell bearing) to the top face? On one of the blocks it measures at:
RH front = 6.870”
RH rear = 6.875”
LH front = tba (hard to measure...)
RH rear = 6.875”
Is there a “standard” for this? I will be checking valve heights to piston crowns etc but wanted to know the base line first.
Thanks in advance, Simon
