Product Details

The Wiseco 6477B125 is a shelf-stock forged performance piston designed for Big Block Chevrolet (BBC) engines. Built to Wiseco's Pro Tru Street standard, this piston features a +40cc positive dome profile and is sized +0.125" (1/8") over standard bore, making it a direct solution for engines that have been bored to the next oversize. As a shelf-stock item, it ships quickly without the lead time of a custom-order piston.

Key Features:

  • Application: Big Block Chevrolet (BBC) engine family
  • Bore Size: +0.125" oversize
  • Dome Volume: +40cc positive dome for increased compression ratio
  • Dome Profile: Quick 16/16" dome design
  • Construction: Forged aluminum alloy for superior strength and heat resistance versus cast pistons
  • Series: Shelf Stock — ready to ship, no custom lead time
  • Rings Included: Matching ring set included per Wiseco Pro Tru spec
  • Wrist Pin: Full-floating wrist pin design
  • Pin Retention: Spiro-Lox retainers (use only Wiseco Spiro-Lox)

Wiseco forged pistons deliver the strength and dimensional consistency demanded by high-performance and racing Big Block Chevy builds. The +40cc dome raises the compression ratio above flat-top configurations, ideal for naturally aspirated performance builds seeking maximum cylinder pressure. Always verify dome-to-head clearance before final assembly and consult the included piston spec card for recommended piston-to-wall clearance values.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

The floor mats I purchased for my car work like a dream. They were just as described in the listing. The shipping was also pretty quick. I just wish the price was about $20 cheaper. Other than that I was completely satisfied.

I have looked for this product many times but was disappointed<br>in the price. could not beleive the price at Autoplicity. thank <br>you very much keep up good work Ray

Low prices, Fast shipping and great service!

Quick and efficient, Thank You!
