For a RR built at the end of April in 71, what would be a good cast date for a 383 block? Thanks If you are looking for something that visually appears correct, I'd recommend going for the correct stamping on the distributor pad, not the block casting date.

G 383 HP & a date on the pad under the distributor if you want to get crazy - get a '71 383HP with a VIN stamping from the same plant as the subject car: "1G123456" or "1R102030" etc. here's a '70 "F 383 HP"

I don't understand the purpose of this. What are you trying to tell people? If it isn't the original motor, what difference does it make at this point?
I have mechanical Aptitude. I can screw up anything.

I recently acquired a 71 383 and it had a cast crank, did all 71 383's have cast cranks or just the non-hp blocks? Only 2-barrel 383's got the cast crank in '70-'71. Why? Money, why waste more expensive forgings on a lo-po motor.

My original 440 Assy date is 2 weeks before the SPD The original 383 for my Super bee ASSY date is 1 day after the SPD on the tag ... both are original pieces ... it can be all over the place and the later in the musclecar era the longer the gap could be??? Casting date has to be before the ASSY date obviously , I have seen as close as 3 weeks myself, some have been closer. Hemis are all over the map and I know of a 71 6pk car that ASSY date was months before SPD. It's never going to be original so get whatever you can that is before ...
