3.5 to 3.2???

[Dmitrikr]

Joe-
Theres no physical difference between the 3.2 and the 3.5 on the exterior of the motor, amd unless the inspector really knows his stuff, the only way to tell would be to get the vin off the block.

there is only one plate with VIN number and is riveted to the cylinder head, not to the block - can be removed/replaced
(at least on four isuzus I did engine work)
