Atlas 4, 5 & 6 Cyl (2800-4200) to SBC, LS and BOP Bellhousing Adapter

Product Info

Introducing the new Atlas to LS, SBC, BBC and BOP (and sometimes C) transmission adapter! Includes all bolts and extended bellhousing dowels for most GM V8 to Atlas fastening applications. (Torque converter and transmission pilot bearings may be required, please see the Vortec 4200 wiki for specifics for your application.)

• The adapter is designed to fit all Atlas 4/5/6 engines, and has a relief area for the balance shaft cover on the 4 and 5 cylinder, no modifications required.
• Made of 10mm thick 7075-T6 Aluminum for weight reduction and strength. There is not excess material here that is not needed. 7075-T6 Aluminum has a higher tensile strength and hardness than mild steel, but is almost half the weight.
• To ensure no pulled threads, all bolt holes are machined to tight tolerances. The threads were tested multiple times to a torque of 120 ft-lbs with no deformation (factory torque is 40 ft-lbs)
• Extended length locating dowels are precision ground for a precise fit.

These adapters are designed from scratch here at Atlas Industries using production parts, CAD/CMM work, and good old hands on testing. I am very proud to offer this and stand behind my work: There is a lifetime warranty to the original purchaser on any pulled threads due to material failure or bending when torqued to factory specifications, I'm that confident in the design and material.
