71 340 Small Block Water Pump Bolts

[Convertcuda]

Hi Everyone,
I bought this 71 340 engine and it has a bunch of mismatched fasteners holding the water pump on. Does anyone have any good reference pics, lengths, bolt head marking for this? Thanks for any help. Looking to replace with original bolts not repro.

I think @MMC Detroit  bolt book shows them all.  Well worth the money.

You can also stick them in the holes and look at how much sticks out. There should be about 3/4"-1" to thread in. Don't forget to use thread sealant when you bolt them up.

Thanks. I misplaced my book so I need to find.

Hey Ken, you can email me. I have Dave's book and may have the bolts used.
