Here is a picture of the A3 heads I propose to use on the 408 stroker. I also have aquired a SCAT crank that is stroked to 4" and uses chevy size connecting rod journals. I have purchased two different manifolds for the heads but the Roush was ported out so bad I would have to fill the runners with metal to get it to port match. So I bought another Edelbrock manifold in new condition that I was planning on using.
As of recently though I started thinking about the block and whether or not I really want to use my old CobraJet block. It's a four bolt main block and has not been overbored as far as I can tell. But I don't want to rebuild the motor ever again, that is I want to build this thing once. For $1700 you can buy an SVO block that uses the smaller journal crank main bearings and windsor front assembly. The SVO block can be bored over safely, is stronger, has better oiling system, and cooling system. Also you can get the aluminum version ( Z351 ) from Race Parts Distribution for around $3k. The Z351 can be bored and stroked to accomodate 427 cubes! If budget allows I think this is the best option. Of couse I would only stroke/bore it to 400 or 408 cubes, which should leave me with a very strong, trouble free block. At least thats the plan.
