It is a Fiat 850 rod bolt. M8X1.0
In much the same way that you can buy 3 sets of 20 ARP small block ford head bolts for the price of one set of 10 ARP fiat head bolts I am trying to save a few clams by using bolts from another application. Honda bolts were close. If they weren't 9mm they would have been perfect but the 8mm are not the same style. They have a "T" cap.
Any of the knowledgable folks here know of a more common motor with rod bolts of the same dimensions? Just trying to avoid getting hit with a $149 bill for a set of 8 ARP rod bolts.
It was quite a simple decision to tap the block to 7/16" to use the larger, stronger SBF head bolts. The rods don't have enough material to drill and tap for use with the honda pieces, hence I turn to you.
