NOTE - PCM no longer sells the R028010 Manifold for the 454 engine.

In order to convert, you have to use Barr CHVA-1-84 and 20-0082 and then use the small piece of 3 inch hose as a sleeve to allow a 3.5 inch hose to slip over it.

This kit contains:

• 1 Exhaust Manifold - BARR-CHVA-1-84

• 1 Manifold Gasket & Hardware

• 1 Riser - BARR-20-0082

• 1 Riser Gasket & Hardware

• 1 - 3" Hose Adaptor Sofwall No Wire - MPI-200-3000

• Converts the OEM manifold R028010 to this after market kit

• PCM Big Block Manifold Conversion Kit

Fits Starboard OR Port Side

Sold Each. You will need 1 Kit Per Side so if you are doing both sides, please order 2 of these kits.

Also please note, you will need to lengthen or replace your 3.5 inch exhaust hose because this system is a little shorter run. Estimated about 18-24 inches but please measure as this is just a guess.
