The NHRA Technical Department recently made changes to the blueprint specifications.
This change is in regards to the use of the Mopar Performance 2836139 (LD-4B) intake manifold for the 1965 thru 1967 Mopar Stock engines. On December 4th, 2019 the NHRA Tech Dept. deleted this part from the Blueprint specs. This was done following extensive research and review of our files from the manufacturer. This part was not an OEM part and was a dealer replacement. Per the NHRA rule book equipment other than factory installed is prohibited. On January 1st, 2020 this part will no longer be permitted.
