Product Details

The Hedman Hedders 78500 Tight Tubes headers are specifically designed for Mopar small block applications, featuring an innovative low-profile design that provides superior clearance in tight engine compartments. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next.

Key Features:

  • Patented TIGHT TUBES clamshell-style collector allows for a low-profile header design, while still providing beneficial exhaust flow improvement over factory manifolds
  • 1-5/8 inch primary tube diameter with 3 inch collector diameter
  • Reducer outlet size: 2-1/2 inches
  • Uncoated mild steel construction, shipped with temporary black paint
  • 5/16 inch flange thickness
  • 16-gauge header tubes for durability
  • Sold as a pair

Application:

These uncoated, TIGHT-TUBES headers fit a variety of 1967-1974 MOPAR passenger cars powered by Chrysler's 273-360 LA engine (inline port pattern only). The flat-style collector also makes these headers ideal for SB Chrysler equipped street rods and custom projects.

Package Contents:

Includes headers, gaskets (when applicable), 3-bolt exhaust adapters, and hardware.

Installation Notes:

  • Mini-starter required
  • Modification to shifter linkage may be required
  • Compatible with air conditioning, power steering, and both manual and automatic transmissions
  • Temporary black paint will burn off when submitted to normal operating temperatures

Important: Not Legal For Street Use on '75-Later Model Years! Legal for off-road use only.

Hedman Hedders has been manufacturing quality headers in the USA since 1954, and classic musclecars is their specialty. Backed by a Limited Lifetime Warranty on construction.

Excellent. Very user friendly. I would use Autoplicity again for my automotive needs and refer friends and family, also.

Grateful

Order arrived and was good service.

No problems. Experience was really good. Thanks

great pricing and received my purchase quickly. the box was a bit torn up, but the contents were fine.

Lowest price I can find! Sent tracking number via FedEx without trouble! Would recommend!

I'm a stickler for finding the best prices on my purchases, while also making sure that the products I buy are legit and not some cheapo knock-offs.<br>I did my homework on the Clutch Stage 2 kit I wanted for my Spec V and found that Autoplicity had the best price anywhere, even a spot where I had 10% off came out to be more expensive.<br><br>I received my Clutch Stage 2 clutch kit pretty quickly (about 1 week) and everything was as expected.<br><br>Overall I would rate Autoplicity a perfect 10, although I did not have to contact their customer service or initiate a return, so the '10' would be on product selection, communication, website experience, and overall feeling that I got the best deal out there.<br><br>Thanks!

Ordered a Simpson helmet on Monday afternoon, received tracking on Monday evening and will have the product on Wednesday! Quick service! Also would like to mention that the price was the lowest of anywhere I looked up.

Autoplicity had the lowest price online for the product I needed. I will definitely buy from them again.

Great website and the ordering was easy too. I like the way they show the full price including shipping and tax. Got the confirmation immediately and the shipment notification the next business day. <br>

Very easy to order on line and excellent communication, very good price.

Simple

Great seller! good communication between autoplicity and buyer!<br>Also very quick to process and send out product! Got order within 6 days standard shipping! Will purchase from again!!
