FWIW, What I described gets you pretty much what you get with the crate motor.
The only significant difference would be the magnum crates have a roller cam.
An LA engine has the shaft rocker set-up and roller rockers are not going top
buy you much unless you are going to be spinning some serious rpms. The
manifold price was for an Edlebrock RPM Air-Gap which is far superior across
normal street operating ranges to the M1 dual plane and is superior to the M1
single plane up to about 6000 rpm where the M1 would start to pull ahead. The
pistons listed are also for Keith Black Hypereutectics and will give you about
9.5:1 compression with an .039 head gasket and typical LA head chamber volumes.
Better quality push rods and high strength rod bolts would be good additions
and would only add $150 or so to the cost.
What I described above is the 360 I have sitting on the engine stand in my
garage and will be going into my 68 Barrcuda.
