Maybe there's already a post here somewhere before.

Have mild 350 pontiac firebird - just a mild cam and headers, turbo 400 and am putting stock 68 manifold back on - currently running torker with a 600 vac secondary holly.
Thinking of putting quadrajet back in place of holley on the stock manifold...hoping to get better milage???

you'll probably not only get better mileage but better performance too

yeah, that's what I've been told and kinda realise myself....tnx...
