Rod Bolts

After searching and asking all I found discussed was the 351C ARP rod bolts for a replacement.
I bought a set and measured them and it was going to take some reaming of the rod bolt holes in the rods or turning/polishing the new bolts to the correct size. The top of the shoulder was about .380.
So I bit the bullet and sent a stock bolt to ARP to see if they could match it up.
What I got was a more direct fit, readily available rod bolt.
He said the original listing is for a Studebaker engine.
Here's some pics and the part number should others need/want them.
I will add additional parts and fasteners I have selected for my new 308 when I start a complete write up on the build.
I was hoping to have it done already but it seems winter is the build season and I have been swamped with EFI conversion kit orders.
Not complaining but it really hurts my build time!

    Looks good.  Now what about the palnuts?

    You can see the new 12 point ARP nuts that will get a drop of Loc-tite.

                                                                                                                                             I would not bother with Pal nuts especially using ARP fastners

    (actually, I haven't used Pal nuts on a 308 since late '50's when I circled Track raced Hudson's)

  • I love this forum, I needed this exact information today (holding rod bolt exemplar in hand)!  I will be ordering my own in the morning!
    Thank you BillUSN1
    Can't wait to see more of your engine build...
    Also happy to put a proper name to the Pal nuts I removed...
