Viton Main Seals - With the mandated removal of asbestos from the factory type rope seals, increased leakage has become commonplace. To address this problem BOP Engineering has designed a new rear main seal for the traditional Pontiac V-8’s.

These seals are not a retrofit from some other engine, but designed from a clean slate using state of the art technology and the best materials. Testing has shown a significant reduction in drag over the factory rope seal, and no leaks!

Available in both 3” for 301- 400 engines and small journal
IA blocks and for 3 1/4” for 421 - 455 engines and large journal IA blocks.
