I bought my pistons and rods assuming my block was going to be good to go with just a hone job. Well it's looking like it may have to go a little further than the clearances will allow for my pistons. Had I bought even a slight over bore piston I would have been good. That being said, If anybody has a good bore 6.0 that they just want to build to a 370 just because let me know. Id like to swap blocks with you.

I know this should be in the trade section but it made more sence to me to put it here.

 

Have you contacted the piston manufacturer to see if they will swap out the pistons for you. Wiseco swapped out my 4.035 shelf pistons with a custom 4.040 piston when machine shop #1 overbored my block.

 

i will but these were custom made already.

 

.003 cleaned up the bore giving my pistons .007 clearance. Is this going to be too much? I'm at 10psi daily and right now 15psi on the high boost switch. May be more later on.

 

That is the clearance mine had after machine shop #1. Based on my talks with a few experienced builders and advice from a couple other forums, I opted to have mine redone. What size pistons do you have now? Have you already had the machine work done?

 

He was finishing the block up as far as I know yesterday.
