question about arp rod bolts

I know the 350 arp rod bolts are longer than 400's, but will 350 rod bolts work in 400 rods, or are they too long all together? A little back story: A buddy of mine is building a short rod 383 for his s10, he went to our local speed shop and bought a set of ARP rod bolts, and bought a set of 400 rods from me. They don't have a set for a 400, and he can't take them back now, so I was wondering if he can use them, he already has the crank, rods, and pistons.

The standard lenght rod bolt is a bit over an eighth inch longer than the 400 bolt. The 400 upper shank lowers the bolt by that amount. This will put more of the unthreaded length into the cap's bolt bore and will hang the threaded end .140 inch further toward the pan rail. I don't have a 400 rod handy to compare but the problem areas could be not enough thread to secure the nut properly plus I'd expect the extra bolt length will interfer with the pan rail as this clearance on the 400 is already tight.

You can always mock this with the ARPs in the 400 rod and check it out since he can't take the bolts back anyway so putting a few scratches in their finish isn't going to result in not being able to return them.
