i have added a aluminum intake(edelbrocht)Carb(edelbrocht) and fixing to pull the stock exhaust manifolds off and replace them with a nice set of headders,they are coated plus will be adding 3" exhaust from the headders to the new flows and out of the flows.Should that help my 351M built over to a 400 breath and sound alot better plus gain some more torque and power?

Yes you will benefit alot, since this engines are always restricted in the exaust ports...

edelbrocht? is that german for edelbrock¿¿
