Not sure if this has been discussed previously or not. A few questions: Do any warranty unstamped VIN black have the HP stamping into the top pad? Since there are three versions of a 1970 production 383(383+2, 383+4 LP and 383+4 HP), would there be only one generic issued block to cover those three options or a seperate block for each?? Would this also apply to 1970-71 440 blocks, 440+4 LP, 440+4 HP and 440+6. Does anyone have pictures that they can post showing pad stampings that they have or have seen? Thanks in advance for your input everyone.
