Hey fella's.I picked up a 1987 3/4 tonne 4x4 and put in a 1987 454 V8 drive train.The engine is out of a 1987 1 tonne dual axle flat bed.I was woundering what is the horse power and tourque of this 454 V8.Its a carb engine also.And secondly what do i have for axles on the 87 3/4 tonne chassis,are they dana 44 or gm 10 bolts or what.The reason im asking is cause i cant seem to locate any casting numbers or tags to ID the axles.Im new at the chevy thing so i hope some one can help me out.Thanks

 

RE Engine HP: by now, it could be anything from 150hp to 400hp depending on if it was rebuilt and with what or if its still stock. chances are its putting out like 250-300hp with close to the same torque.

 

You should have a GM 14 bolt rear, I'm not sure but I think the front would be a Chevy/Dana 44. Here is a differential identification chart to help. http://www.rocky-road.com/diffid.html
