lose that street avenger carb... bet a true double pumper or even a properly set up Q-jet would get much better numbers (& mpg with the q-jet) with everything else the same.

Edited my post, as I miss read the dyno sheets.


Don’t know, seems like a nice build for a driver to me.

I think the RPM & Qjet would be a good set up though.

yes nice build for sure, my comment was only about the carb... im sure it will work ok but they dont get very good reviews & a correct Q-jet set up right would run much better. probably fit the shaker better too.

i had one of the 770 street avenger carbs, was brand new & came on a stroker motor i bought, they guy bought it because it was shiny & looked cool... i sold it to a friend who used it on a aluminum head stroked ford, the shop that built the engine said it was horrible to get running good on the dyno & they had to rebuild it to get it to run decent & even then suggested he find a different carb to use.
