Any grinding necessary to swing that 4.25" crank in the Gen V block?

Don't know yet, I have done a bit of research , it seems it is a block by block basis. I will definitely post that process when I get there...
Initial clearance looks good , more than enough here is my

Hey

Good project Derek. I have a '92. Runs great but it is showing its' age! Just take your time, be thorough and take pics write it all down like you are, to document along the way. A short pencil beats a long memory. A few questions just for consideration....

1- Why the screens in the lifter valley. You may be wasting your time, and building in something that could be problematic in the future. If you are worried about stuff getting to the bottom, such as a valve keeper or push rod tip maybe, they would almost have to defy gravity to get there, and then your prime concern would really be pulling a head to get the valve out of the piston,replacing the connecting rod, and maybe repairing the cracks, if possible.

I know it's old school, but it would be better to paint the lifter valley to help move the oil down to the pan.

2- Where are you getting those bore measurements from? Way to small for the big block.

3- Are you sure on those tolerances? A thou? Tough to get all eight within that margin. Even GM didn't do that at the factory on the engine production line back then.

Keep at it !!

Bill

Hey thanks for the good advice.

The lifter screens were suggested by someone I trust, and they seemed to be cheap insurance from top end damage.
I am trying to take good advice from reliable people, this is the first engine I have ever built.
Next, these were crank bore measurements from using my telescoping bore gauges.

I just wrote down what my mics were telling me, I'll double check .

Thanks for you advice.
