They are night and day as far as size goes. If you are building a Zingers type of car, 1/16 parts would be great for that!
Here is a pic for reference. No mine models.
Smallest is 1/25th, second is 1/16th and the biggest is 1/8th
Nobody kitted a "Gasser" in 1/16th scale. The closest would be to start with an AMT Chevy and start scavenging other kits for parts or get some 3D printed / resin parts.
Nooo! The dopey Trick Wheels are still in it!!!! Come on Revell, it is not like I wanted you to also make it a solid front nose! Just some decent wheels!
