ok well have found a bit of information and it looks like intake off smallblock will not work but can be found on ebay very cheap! injectors will need to suit a bigblock. From what i have found it looks as if the engine wiring loom and ecu from the ls1 will work on a bigblock, in saying that i gather that the bolt on electrical stuff like the starter and alternator ect... should be the same for a big and small block? I have probably missed alot of other stuff so if you know of stuff that i would have to get specific for a bigblock that would be great. The way it's looking i think price wise it would be a pretty dam good conversion!
