dynoed my 416
US Car Tool sub frame connectors would be helpful as far as chassis mods go.
Ryan at Shady Dell Speed Shop told me to run a 750 Holley Double Pumper for the street 414 stroker I am building. He says on the dyno an engine like what I am building will only really need about 710 cfm of flow. He says I can run a bigger carb but it won't help. I am going with Edelbrock Stage 2 ported heads from Shady Dell. He also recommended a Crane 699641 hydraulic roller cam which is what I will be going with.
