everything else is fine cant remember what cams i used but can find out for you.
uprate your clutch aswell and cooling system and use a good breather system from both sides of the block.
Cant go external wastegate with a 4x4 manifold can i?
Ive gone for a 4x4 water pump and housing. 50mm core alloy rad. The enough do you think?
I was going to breath from both sides of the block upto a catch tank, think thats the same as you have done it?
