360 magnumblock?

Hi all!
A magnum compared to a la is what you are asking and specifically the 5.9 or the 360.

The 5.9 uses a factory roller hydraulic cam, and the rocker arms are pressure oiled through the pushrods like a shivvy, the rockers are very similar to sbc and should be replaced w/good stuff in hp apps, the heads are magnum swirl port and can be made to flow well, the intake bolts go strait down, has a nice timing chain tensioner in place of the typical cam retention plate (these can be used on LA motors too, around $30).

The 360 uses a hydraulic flat tappet cam from the factory but can be fitted with your choice of cam type, oils through the block up into the heads and delivers the top end oil to the rockers through a single shaft mounted on each head (this set-up is extremely durable even in stock stamped steel form if you don't go crazy with lift)

OK, I just thought about a resource that can keep me from typing so much...LOL
