By Doug Dutra and ARP

I worked with ARP a few years back in order to develop a source for SL6 engine builders to get high quality bolts and studs.

Here is some general information and background on the fasteners needed for the cast iron and Aluminum Block
Slant Six Bolt Size & Torque 

Note that the SL6 main studs are the same as the Mopar Big Blocks, the con. rod bolts are the same as the Pontiac 455 if I remember it right. Bottom-line is that we were able to "cross" all the cast iron SL6 fasteners over to other listings ARP was already stocking, everything except the Alm. Block SL6 hardware, that stuff has to be special ordered.

I will let photos, pages and letters describe the rest. (Click on any image for a bigger view)

Go to the Alm. Block link for more photos and info. on the special custom made studs for this engine. - DD
