Edelbrock Thunder series 800 on 408 stroker???

I run a 750 Performer carb on my 408, after tuning (using a o2 sensor) it runs very good. From what i´ve read the Holley´s should make a few more ponies. I think the 800 AVS is a good carb for your engine, with that cam you should set ignition at least 20° - 22° btdc in idle, and i use the stiffest step up springs (8" i think). Just don´t expect this carb to work 100 % perfect out of the box, i had to reduce the primary jets and enlarge the secondaries. The o2 Sensor was very helpful, so put a weld bung into your collector.
