SWB Big Block Truck
I found a guy that has what looks like a '72 SWB Fleet with a 402. He says it's the original 400. Is there a way to tell from the vin number if the tag is not on the glovebox door? Also, the rear view mirror attaches like a 71 from the top of the cab...? I may be able to pick it up but don't want to overpay. thanks.

The VIN will only tell you that it is a V8. Look for emission stickers on the inner fender and the radiator support.
Look at the stamping code and post it. We should be able to tell you at least if the block was original to a '71 pickup (post the VIN too so that we can decode that for you too). I think the stamping on a BB is the same as a SB - on the front of the block, on the same surface the head would bolt to on the passenger side. It will have a code like T0625TMD or something. Getting the casting numbers off the back (on the webbing where it bolts to the tranny on the driver's side). Look for a build sheet in the back of the seat too.

A couple of things to look at:
Big block engine mounts were different in 72 from the 71, (motor mounts are like the later style and the towers are very different) Original big block trucks should have a tin shield screwed to the cab on the passenger side as an exhaust shield. Look closer at the mirror where it is mounted on the cab. The 71 cab will have a raised hump for the mirror and the 72 will not. Some guys got tired of the glued on mirrors and screwed the earlier style on. Good luck! Jim |

The serial number that is stamped on the block (pad is located in the front of the passenger side head) should match the VIN tag serial number and the frame stamping as well. Take a look at this:

Here is the raised pad Jim was refering to. On the '70 and older there was no raised portion. I kinda wonder if it isn't a truck slapped together. (Always skeptical)
Also, if an original big block, it'll have a remote mounted power steering resivour...at least, if equipped with power steering. |

If the cab was a big block cab, it will have a high hump. You can also check to see if the VIN on the cab matches the one on the frame. The VIN is on the frame on top of the frame just behind the steering box and in front of the motor.
