What am I looking at?

Most are 3.73

So 33 or 35 inch tires are perfect with 4.11s or 3.73s. Although they could be 3.07
You never know

An 87 should be TBI unless some hillbilly has hacked it up
And slapped on a carb

Careful with shiny paint
It’s usually hiding rust and bondo

Take a refrigerator magnet or one of those magnetic business cards and lay it on every rust prone area

Basically the entire lower half of the truck or anywhere within 6 inches of the bottom and around the wheel wells

And on the front fenders between the headlights and wheel well

Lots of trucks have bondo there from fender bender accidents

I have 411s and 315/70r17 = 34.5" was running 2100 ish rpm at 55 last night in drive, granted thats not alot but I also wasn't going 70mph.

3.07 in a 14 bolt, thought I remember reading 3.21 or 3.54 was the lowest option.

Never seen a th 400 in 87

It was a bust. Truck isn’t even finished with the axle swaps so can’t be driven. I’m starting to hate craigslist.
