As in, if the bore & hone work done by the "old" shop who machined my 448 short block doesn't compare favorably to the work being done to my 452 block by a "new" shop, would it be feasible to have the "new" shop re-do the other place's hone before I bother assembling the engine? Yeah, I know... I'm

Most motors I know of run better on the 2nd rering hone Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

The negative would be a looser resulting piston to bore clearance; assuming it was correct after the first hone. If it changes 0.0005" or 0.0020" just depends. 1993 Daytona, 5.50 at 130mph (1/8) 1.19 sixty ft (PG). Link to 572 B1 - Part 1

My 383 for my stroker was rehoned , not sure when it was screwed up, 1st time or the 2nd time , but the cylinders are hourglass shaped now and have to go to the next overbore to clean up ... good thing I have a spare block already machined

Depending on the angles and such, I can't see how you attain proper oil control with two different sets of grooves. Not to mention piston to wall clearance gets worse.

Change in bore size was practically immeasurable with .0001" bore gauge. Yep , have to be on it all day & some to remove any material from cylinder wall when using a dingle berry (flex hone), these give a real good finish depending how fast you spin the drill along with how quick you pull it in & out , gotta get a real fine balance with these.

I'll have to dig up the ol' digi-cam. Quote: what exactly is wrong with it? Uhhhh... probably nothing... other than it's mine and I'm second-guessing the work done because of a couple of other things about the block that have me thinking "" about how much to trust the work.
