Better do a bunch of measuring. Compare frame width along its full length, amount of kick up at each end (Suburban is flat in front and kicked up way less than many new vehicles in the rear), and steering shaft location are just a few things that come to mind. You will have to fabricate everything from shift linkage to pedal locations and linkage (gas, brake, clutch). I have a sign over my desk that says, "We can put a 450 Cummins on a skate board if you have the Cummins, the skateboard, and the money", but in the vast majority of cases it is far better to add updates to the existing frame. My storage lot is full of unfinished dream projects. When one asks me advice on chassis building or swapping I ask them what they know about Ackerman Angle, Anti dive, roll center, etc. If this draws a blank my advice is to hit the library, or cumputer nowdays, and bone up on what will make either an enjoyable ride or a dangerous/abandoned project. Now with all that doom and gloom off the table I love to see an unusual project with a bunch of new innovations and a lot of thought put into it. When we were racing I always studied even the crappiest most shoddily built cars because invariably they would have maybe just one great item or idea that was worth remembering.
