Megablock Q’s

I have a Cummins era Siamese block in the rebuild stage. I’ve done some research but finding limited info. Is there a main stud kit available from anyone? I found one for a world block, not sure if it would interchange. Is there an off the shelf 4.5 bore ring set ? Found stuff listed for Chevy stuff. A bore is a bore ?? Need 1/8 1/8 1/16. Builder prefers Totalseal.

Rings, no problem. Call ARP and ask, or search Jegs or Summit on the stud kit.

Called ARP. Nothing in the catalog. Have to measure everything and see if they can match it up. Nothing in the milodon catalog online. Time to measure I guess. Thank you.

ARP 145-5602 is what you need.

Yes, this is the kit I used on my Megablock Hemi. However, my main side studs were just a little too short for comfort. Hardly had any thread engagement in order to install the 12 point nuts. Not sure if it was a packaging error but I ordered some that were slightly longer in length. ARP sent them at no charge.

We stock the 145 5602s

That looks like the ticket! Mine is a wedge, but the block is essentially the same right? Thank you.
