a silvertop will run better on a blacktop loom and ecu but will require custom wiring to make work I believe, I think AceSniper on here or someone may have done it, but can I ask why go to a silvertop?? whats wrong with replacing it with another blacktop would be a lot less hassle

I don't believe there is need for custom wiring in this case, you could even use BT throttle body so not to muck around with MAP sensor line (well it is not that difficult anyway).

The inlet manifold faces are different, but I dont know if they are different enough to cause a problem or not.

If the head is ok, you could buy a Silvertop and use the blacktop head from the old engine.
That way you would get the 'stronger' silvertop rods also, with the benefits of the blacktop head.

Would mean no wiring problems also.
