I ran NHRA stock eliminator many years with my 340 sixpak. Made tons of power, many class wins and NHRA records in C/SA, D/SA. Gave everyone fits, they were glad I gave it up. Every time I showed up, “random” tear down. They took the fun out of it. The 3 Holley set up couldn’t be beat, back then anyway! I would love to have the set up on my Z28!
