I would prefer you use a 4777 to wake your car up.The 800 will need more tuning because it has huge secondaries for a 350.You have a very mild cam. The performer manifold will help you as long as you do not use a spacer.keep it a 2 plane intake. Bolt it on the way it is.Of course check the jets and PV first so you can have different parts on hand for changing.
does that carb have a pressed in booster venturi?Dyno time is expensive but a worth while investment
