Product Details

The Hedman Hedders 68370 is a high-performance exhaust header specifically engineered for Chevrolet big block engines (396-502 cubic inches) in street rod applications. This painted header is designed to maximize exhaust flow efficiency, replacing restrictive factory manifolds with smoothly mandrel-bent individual primary pipes for each cylinder.

Performance Benefits:

  • Utilizes scavenging effect to extract exhaust gases more efficiently than stock manifolds
  • Increases horsepower and torque for improved passing power, towing capacity, and load hauling
  • Reduces cylinder temperatures by eliminating exhaust gas bottlenecking
  • Improves fuel efficiency by allowing complete cylinder filling with fresh air/fuel mixture
  • Engineered with racing-derived technology for maximum performance gains

Installation & Construction:

  • Purpose-built for engine swap projects and street rod builds
  • Designed for straightforward installation with included instructions
  • Durable painted finish protects against corrosion
  • Precision-fitted primary tubes optimized for big block Chevy applications

This header delivers the performance advantage of increased exhaust velocity while reducing backpressure, making it ideal for enthusiasts looking to maximize the potential of their Chevrolet big block engine in a street rod chassis.

Autoplicity had an item my vendor had on backorder for weeks in stock and shipped it very quickly. I'm glad i found this place on the web, and will be looking forward to doing business with them in the future!

SUPER EASY TO ORDER, CHEAPEST PRICES!! WILL BE ORDERING FROM THEM AGAIN!

They had the product I wanted at an excellent price. I was very pleased because my order came much faster than I thought it would.

amazing

Its amazing the prices Autoplicity is able to offer some of their products at. The product i ordered was consistently msrp on every site i searched through, yet autoplicity had it for $10 less. Lowest price along with a attractive and intuitive website is a win in my book. Having it shipped in less the 24hrs is another bonus
