I am currently running a 750 Holley 3310 carb with vaccuum secondaries on my mildly built 400 big block. I am wondering if it would be worthwhile to swap to a rebuilt 800 cfm thermoquad, or if it would be unncecessary.
My combo:
-'77 400 big block
-~9:1 compression
-performer rpm intake manifold
-windage tray
-summit cam 282/292 advertised, 224/234 @ .050, .465/.488" lift, 114 lobe separation angle
-stock exhaust manifolds
-dual 2.5" exhaust with glasspacks
Thanks!
