What rear end is in it now? It has to be different from the original because the 400 uses an open drive shaft. If it has a later center section in the original houseing it probably has 3.90 gears. You can get an after market set of 3.38 gears & put them in that rear end or get a later model rear end from a Blazer.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
