Will a Chevrolet LS engine fit into 1995 Chevrolet G 30 van

Yes it will fit physically but will need many things to be swapped over and retrofitted. Not a direct bolt in. Alex

The LS is probably one of the most universal and widely used engines of today’s custom car builders - it has an identical bell housing footprint to the Chevy V/8’s from 1955 to present! There are a plethora of parts available for the swap you are contemplating - you can choose to keep the fuel injection or use carburetor - plus many other forms of aspiration. As stated - it is not a plug and play - but then again most are not - even one from another Chevy Van.
