340 resto or R3 blocks

[Scampin]

Anybody have the torque specs for main caps for the 4-bolt main blocks? I have arp studs in the block, but can't find the part number online to get the torque recommendations.

Contact ARP.

Yeah, was hoping to get an answer this weekend, but will Monday morning.

It might be these….

It’s on the ARP website. Find the part, the part number makes it faster, click on the part and scroll around, they do list there torque specs and any notes that go with them.

I tried, could not find a listing for 4-bolt main small block Mopar. Mostly interested if there is a difference between the inner and outer.

I’ll look in the MP Engines book for a clue real quick.


Edit/addition…

Sorry buddy, I thought there was something there. Perhaps one of the other books makes a mention.

Inner and outer are the same?

Inner and outer are the same?

I would think not as the outlets wouldn’t have the meat to sink into. Bolts would be 100 but I can’t see a stud being that much. It also varies with what u use for lube. Kim. @Oldmanmopar

I did some last year and seem to think they were 30-60-90… but I can’t remember for sure…
