Help! Need some numbers help on a car I am looking

[Mark_C]

Block should be a 618 casting, probably cast 2 or 3 days before assembly. Cars too late for a 388 casting, and to early for an 010 casting. Muncie case will have an A suffix, since you couldn't get an M21 or M22 transmission in an L48 car. The axle seems to be dated to early for the car (doesn't mean its not the original though) but everything else seems to be correctly dated for a late March built car. Need to see the stamps to see if they are original though.

tranny does have the A suffix but is the 388 the worng block casting?

[1970ChevelleSS]

block casting is 3932388
Date A-8-9

The majority (if not all) of small block pace cars I have seen all have had the 388 block in them, even April cars and they were real.

The block casting date and assm date are far apart... have you seen the stampings? Broach marks?

[Mark_C]

That far a spread in casting date to assembly date on the engine would raise some red flags for me. Not impossible, but also not very likely. Get pictures of the assembly code and VIN stamp on the block.

My block casting on my 388 block is A 3 9. My motor is TO319HA. A perfect match. Car is 04A. Nothing wrong with these numbers. Rear is C179
