Product Details

The Enginetech M38058-040 is a moly-faced piston ring set manufactured for the GM Buick 350 cubic inch (5.7L) V8 engine in .040" oversize. Enginetech's "M" prefix ring sets feature plasma-moly face coatings on the top compression ring, providing superior wear resistance, improved oil control, and faster seating compared to standard cast iron rings — an ideal choice for engine rebuilds where maximizing performance and longevity is the priority.

Key Features:

  • Moly-faced top compression ring for reduced friction and extended service life
  • .040" oversize bore sizing for engines that have been bored 40 thousandths over standard
  • Designed specifically for the GM Buick 350 V8 engine family
  • Three-piece oil control ring assembly for effective oil regulation
  • Precision-manufactured to OE specifications for proper fitment and sealing
  • Compatible with Enginetech piston sets using part numbers R38058 or M38058

This ring set is engineered for engine builders performing a full rebuild or overbore on the Buick 350 V8. The moly coating promotes quick break-in and delivers consistent compression seal over the long term, making this a trusted choice for professional engine builders and experienced rebuilders alike.

Delivery man was excellent. The AC unit was plug and play.

Great price and quick shipper. Thank you.

Straight forward, price was good, shipping was fast.

Prior to purchasing I made an inquiry and recieved no response.

I never received anything about shipping so I contacted customer support. They said it was a direct shipment and they would check on it for me and get back to me. I never heard back from them. Shortly after that I did receive a message from the carrier saying they have my shipment and scheduled a delivery. They said they would call me 30 mins before the delivery so I could get off work and come to inspect it before signing for it. That didnt' happen either my wife called me first thing in the morning and say they are here delivering it now so I had to run home so I could inspect it. The driver was really nice and waited for me to get there.

Very easy transaction.

The online purchasing system is very efficient. I had an issue with the delivery times, and the company quickly corrected the situation to my satisfaction.

No issues

All good
