Speedway Motors 9300102 Details

  • Compact design fits a wide variety of applications
  • Made from 16-gauge tubing
  • Includes reducers, gaskets, and bolts
  • 1-3/4” primary tube diameter
  • 2-1/2” collector diameter
  • Can be used with most oil filter systems and transmission/starter combinations
  • Will not fit 55-57 Chevy cars, Camaros, or other modern vehicles which have a crossmember below the engines center two exhaust ports
  • Fits standard deck big blocks only

Overall Assessment

Customers praise the product for its heavy-duty quality, including sturdy flanges and superior gaskets. The headers are applauded for their perfect fit, even on vintage vehicles like the 67 Fleetwood or Chevy Impala, despite requiring some modification. The completeness of supplied accessories, such as bolts and gaskets, is also praised. Although some buyers faced fit issues due to specific car models, the product's performance and value outshine minor setbacks. Notably, the headers saved one customer from an expensive steering adjustment, indicating an exceptional practicality in tight spaces.

I'm dumb and thought it would be easy to put a 454 in a 67 Fleetwood. Nothing else came close to working. These still took some modification to the collector but thats not the headers fault. Heavy flanges and decent gaskets.

Great product and purchase.

It was a smooth purchase and delivery to New Zealand. The They supplied all the gaskets, header bolts, flanges which was unexpected but very pleasing with a great fit into my 5 window coupe. I couldn't get any in NZ near the price I got at Speed way.

These saved me the trouble and expense of moving the steering on the car I am working on. They do their job in the small space available. They came with all the bolts, nuts, and gaskets needed to do the job. I lucked out when I picked this pair, as I was in a tight spot in more ways than one.
