what are you going to use to bore and hone? this isn't something you can do yourself its a specialist process
thanks for the reply , I'm not much of an engine builder , this is my first attempt (with some help ) lol
I'm going to bore to within 0.004" of the 0.020" bore , then hone using 220 and 280 grit , then finish with 400 grit to reach the 0.0035 clearance
and as u said use pistons 1-4 and measure clearance on each piston to cylinder
You need to bore to 0.003" and then hone, not 0.004" and then hone.
And as Tim said it is a specialist job.
I would recommend that you contact Wiseco and ask what clearance and what grit hone to use in what stages.
And then take it to a REPUTABLE engineer shop to have it done.
