Came anyone give some more information on this block?
Cast # 3902406 with PASS on the next flat up from the cast, it also has Hi-perf Truck/Pass behind the bellhousing surface. 396ci I think.
# on forward pad is
T06 16IV
7R181554

Another block I have which I think is a 402ci.
Cast # 3999290 with GM10T on the next flat up from the cast, It has Hi-perf PASS behind the bellhousing surface.
The number on the pad is very hard to read but looks like the #'s are CE55800 1, all I can see is the bottom of the numbers on some of them.

Thank in advance for any help you can provide.
Jeff

3902406 = 1967 396.
Engine Code "IV" = 1965-68 396/325 auto trans.

3999290 = 1972 402/240 2 bolt main. The CE engine code is a replacement block.
