If I have new ARP studs installed (461 olds) is there a major difference in using a .0005 or .0001 dial bore gauge to check the mains. Before the studs i had stock bolts. The machine shop that installed them said they checked and everything is in spec and doesn't need an align hone. I want to check myself but I'll have to invest in a bore gauge myself. If someone can help i would be greatfull! Where can I find an affordable dial bore gauge $40-$150 that's will get me accurate results. Is there anything else I need to check to make sure it doesnt require a align hone? I saw one at eastwood .0005 for $60. since align hone should be the first step at the machine shop can it be done last if I end up needing one? someone said to just install the crank w/o the rear main seal and see if it turns. i want to get this done right. Thanks everyone who looked!

IMHO, I would get a .0001 dial bore gage by Mitutoyo, due to the tolerances. I would look on ebay or pawn shops for a used one though.

Bumping this. Anyone have any suggestions for a dial bore gauge? I am in the same situation as the OP but I am using ARP main bolts.

OP how did the build turn out?

Check MSCdirect.com as they run discount specials on measuring instruments (as well as other items). You just have to catch them at the right time for what you are looking for.

Years ago I bought a dial indicator set online from enco tools. Not the highest quality but it got the job done.

They are msc tools these days:

You can't check bore alignment with a dial bore gauge only concentricity and overall size. Bore alignment would require some kind of straightedge spanning all the saddles

Amozon has one from accusize
for 82 bucks 1-6 inch .0005

I second what TripDeuces said.

Hey guys thanks for chiming in. I ended up going with a Mitutoyo 511-753 accurate to .0001"

The bores seem pretty darn round with the ARP bolts torqued down to ARP's spec with ARP lube. I have not attempted to verify bore alignment yet and understand a dial bore gauge is not the tool for the job.
