That's cool! I've never seen a 2.3 in one of these cars before.
While modifying the old cars like this isn't something I'm personally into I do enjoy seeing what others have done though with different swaps. The metal work and fabrication you're doing is excellent too. The slots for the air intake are a nice neat job too, as if it was "original".
Keep us updated!
