Bolts.....
When putting my new motor back together should I use stainless steel or hardened bolts? This would be for flex plate, intake, exhaust, fuel pump and all the parts that go on a crate motor.TIA.

ARP Fasteners for just about everything. And part that is subject to shear loading should use at least a grade 5, and in some cases grade 8.
The flywheel/flexplate is not a place for a "hardware" grade bolt, lest your Vette may become 2 pieces.
The intake/fuel pum/water pump use whatever you like. Stock exhaust manifolds the same.

I did a little research on stainless when was rebuilding my suspension. I had planned on using a lot of stainless hardware until I learned they are just below grade 5 in strength. Nice not to worry about corrosion, but I'd just be worrying about bolts shearing instead. I'd rather take my chances with a little rust
Haven't dove into the engine yet, but you can hardly find an online post, magazine article or TV spot that isn't adamant about ARPs, sounds like cheap insurance to me.

I used ARP bolt's in all the stress area's on my engine rebuild. I used stainless in the dress up area's.
