Well I thought I had ordered everything I would need to drop my motor in the car this weekend but obviously I miss a few small things. Would grade 8 bolts from the local hardware store work for my flywheel and my torque converter bolts? I had planned on getting ARP bolts but if grade 8 stuff will work then I'll save the $10 shipping charge.

Flywheel bolts are not found at your average hardware store. Around here both Autozone & Advance Auto carry them though. Make sure to locktite them. Does your convertor have threads as part of it, or do you need a nut and bolt?

Don't use hardware store stuff for that.

At least, not if you've become accustomed to having feet, and you think you might want to keep them around a little while longer.

Go down to VatoZone and get the Mr Gasket ones out of their "performance" aisle.

Are the Mr Gasket ones stronger than Grade 8 bolts?

Strength isn't the issue, bolt design is.

the flexplate/flywheel bolts have wider flatter heads than regular grd8 hex bolts

Plus they are harder than any hardware store fastener - try to hacksaw a flywheel bolt into a flexplate bolt - they are fine pitch thread, and have a lockwasher of sorts. I would still use locktite though.
