Serious ARP Bolts Questions from a relic.
Serious ARP Bolts Questions from a relic.
In regards to head bolts. I'm fully aware that ideally you would want to use a complete set and in that is where the questions is.
1. On the Oldsmobile engine there are a couple of headbolts that are also studs for AC Compressor as well as the Alternator Bracket, Are there also the same style ARP Bolts available ?
2. How are people getting around this minor obstacle as using those 2 bolts would be the weak link in a otherwise solid build?
Looking forward to seeing the solution to a relative minor issues for a car with AC.

Do you really need the ARP bolts ? I am building a 350 stroker right now with Edelbrock heads and I am going to use the stock bolts exactly for that reason. Unless you are building some outrageous engine I don't see the need for anything other than the stock bolts.
I checked just to be sure and the stock bolts are the same exact length as the ARP ones that Edelbrock says you "must use"

Use studs instead of bolts and you will have a male thread to which you can improvise a connection. I drilled my AC mount to a larger size and used a very short, I think, 5/8" allen head bolt cut off and internally threaded to make the connection.
Pretty sure you can get ARP bolts with the stud for accessories.
Other options: use a stud in the location for the special bolt. Then drill the accessory bracket to fit the larger stud diameter.
