Add ARP's legendary quality to secure your engine with complete confidence. Manufactured from black oxide finished chrome moly steel and rated at 170,000 PSI, which is considerably stronger than Grade 8 hardware, you can be sure that motor will stay put! Bolts feature conventional hex style heads and the kit comes complete with high quality flat washers.
Got a set of these to go along with my new motor mounts. What should have been a straightfoward installation turned out to be a very frustrating and what we (myself and two buddies) found to be darn impossible. When we tried to install these we could only get about half a turn before they would go no further. At first we thought we were installing them crooked or possibly cross threading them, so we would take them out and try again, and again, and again... We did not want to ruin the threads on the block so we did not force them in. In the end we reinstalled the old factory bolts. These ARP bolts appeared identical to the factory bolts with the exception of the head size (which the washers make up for) and for the fact the factory bolts are slightly narrowed at the tip, which is probably why we had no problems re-installing them (factory bolts). Not sure if I should have placed more torque and forced these in. I found them unusable.

These bolts were a little tough to get if you don't have the 3 piece motor mounts, other then that they are great fit!
