  • what is the initial timing on that? seems it should be a bit more responsive??

  • @Formulabruce

    The intent was to load the engine smoothly on each pull to prevent any irregular dyno numbers at low speed. You can clearly see the rate at which we open the throttle. There's absolutely no shortage of throttle response with this car otherwise. Look at the other videos of it.

  • Nice clean secondary air door operation! The carburetor looks to be very well tuned. You have "sac" as is sounds like the pull was to around 6200 or so. Where does the power curve fall off?

  • This is so music to my ears!  Who needs EFI or a computer controlling everything!

  • i had a lucerne blue & white stripe 72 TA. rebuilt 455 with headwork, cam, & headers. Turbo 400 with shift-kit. when i was 20 yrs old. I paid 1500$ in 1990 turn-key. its a beast.

  • Sounds like it's time for some street racing:)

  • Fuck yeah jizz down there

  • I wasn't impressed until I seen the motor and the car move when they got off the gas. Torque wow

  • Infamous? Sounds like every quadrapuck i've ever had although that one sounds like it's workin good. Nice car by the way.

  • Nice!

  • Mullet wagon

  • Sounds like a Mercruiser 205 i used to have in a boat.
