Video of a 406 Small Block Chevy running on a dyno. It uses a small 390 carb and still puts out over 500 hp!

  • 406 is the new 383. 427's and 434's are just greedy!!!!

  • only rules i've ever saw that seemed to work was , hydraulic cam , cast iron heads , 500 2 barrel , not that it made for great racing action ,, but it leveled the field pretty good

  • The engine was built to run in a late model stock car. One of the rules to keep costs down (didn't work) was for all engines to run a 390 cfm carb. Same theory as NASCAR with the restrictor plate. Restrict air comming in and the engine will make less power.

    Lame I know.

  • why would you put a 390 on a 406 ??

  • That is one bad sounding engine. How did you get so much power with a small carb?
