Since my last block had questionable clearances and I'm taking another block into the machine shop tomorrow, I am going to specify what clearances I want for 'piston to cylinder', main, and rod bearings.

I'm going to have the block decked, bored (with plates), honed for the pistons, cleaned and cam bearings, etc.

For a 550 hp street motor, is line honing needed? A good idea? Or not worth it?

Have a good day!

Its needed if its needed :)

If the mains are out of align, it needs to be done, even if it was a 2000 rpm Perkins Diesel. You wont get the clearances you want if the main bores are crooked at best, and at worst it may not turn

IMHO I'd talk to the machine shop, nice little align hone to get everything straight certainly is in the spirit of everything else you sare doing.

Just a question, how are you determining your cylinder wall clearance? I didnt follow your earlier build, but just making a point that different piston materials have different expansion rates, generally, the piston manufacturer can tell you the best clearance for your build
