That does not look like a good number to me.

Re: Big Block Engine Decode? HELP!!!

Is it possible that the third to the last letter is a "1" instead of an "I"?
If its "IV" instead, it appears to be a 1965 Impala 325HP 396 that came with a T400 behind it. does it have a "cannister" oil filter assembly or an aluminum adapter under a spin on oil filter?
