Question Suburban frame under a pickup?

Can a Suburban frame be used under a pickup body? I know about the different fuel tank locations, but are the any other major differences? Anyone done this before who could offer some in-depth advice? I came across a cherry, un-tweaked, rust free Suburban 4by4 rolling chasis, with a running 454 c.i.d. installed (in place of the factory 400 SB). All for the price of $500.00. So whatta ya say? Can it be done with minor mods?

The burb frame is longer than a pickup frame. It would have to be cut down, a major modification. but if it were me i'd buy it anyway.

I think the Burb frame is longer than a SWB truck but not as long as a LWB truck. I tried to use a BURB driveshaft and it was 2 inches shorter than my old one

These are '76 numbers, but should be the same for all 73-87 years...

Wheelbases:

short bed pickup = 117.5
long bed pickup = 131.5
long bed crew cab pickup = 164.5

Blazer/Jimmy = 106.5

Suburban = 129.5

Flat bed it if your just looking to make a bomb. Move the gas tank up behind the cab and cut it off behind the shackle mounts. There are several folks thinking about dropping crw cabs on Burb frames. One guy is sounding pretty serious. Body is rust out but he has a line on a low rust crew and talking about 4 linking it with about a 4ft utility bed.
