Which 5.7?
The early one the ports are smaller and it will interfere with the front of the block.
Later the ports are the same size but do not know about block interference.
The intake can be massaged.

Just picked up a 06 car and 07 jeep 5.7, both spun bearings. Are these considered early blocks? Did you mean the head ports can be opened up to fit 6.1 intake? How much power difference would you guess between the two intakes, 5.7-6.1? I'm now going back to read this whole post again to get some insite on building this engine, most bang for the buck so to speak.
