Anyone know what the quickest roots blown alky 23 degree bbc is?

Real big block Chevy not big chief 1/4 or 1/8 info is good. Looking for facts not rumors.

Thanks,
Trevor Sherwood

 

Well, I'll start off and say when I ran a roots, it ran a 6.62 @ 212MPH @2730LBS. 4.24 1/8th. I'm sure not that fastest by any means but somthing to get the thread started.

 

We ran 6.69 in a 2700 door car. 510bbc with big chief heads , 14 /71. 20 over

 

Back in 2001 in T/D legal trim (could only run an 8-71 then) ran in the 6.40's with a stock Littlefield/Powerglide/cast Iron Block/Dart 360's When we went Big Cieif/14-71/Bruno.......5's You got that car running good Trev

Zach Sackman with a Spitzer T/D has gone 6.11@233. 557 conventional head BBC.

I have the same exact car and engine as him, except I have an iron block. So far I've been 3.96@181. Only 22# boost.
