The motor is just an ordinary HK 186 motor. The P doesn't indicate any magical (as in HP), it is just the prefix used on standard HK 186 motors.
I've never noticed the red tag on a Holden 3 speed manual.
I assume is an automatic, so it would most likely be a Powerglide or a Trimatic.
If it happens to be a four speed manual that tag might belong to an Opel gearbox which was in the HR and HK. I think the HK Opel had a pressed tin bottom pan. The HR had a cast alloy pan which leaked terribly.
Originally ithad a grey motor and three speed manual or a Hyromatic if it was originally automatic.
If you are more concerned about driveability than originality leave the 186 in it, especially if the 186 engine number is on the rego papers.
If you put an original grey motor back in it, sell the 186 sump and oil pickup on ebay for $200. The 186 will have an EH sump and oil pickup which is essential for fitting any red six inan early grey motor Holden.
If the model number on the ID plate ends with M, it is a factory manual car. A means Automatic.

Old is good.

Transmission is a trimatic from a 6cyl WB ute or van. You can tell its late because the build number is greater than 1 million.

The 186P204841 is out of an HT Holden.

Also what is "magical" about an HP block ? Essentially, those blocks cast HP are just stock 179 motors out of EH Holdens. The HP was to ID them as NOT being a 149. Very late EH & all HD 179 blocks were cast 179, but there were no other changes & there is nothing special at all about a Holden block cast HP.

As you say, there is nothing magical about a HP block. Some people, not me, believe the 186P is a HP also.That is why I said there is nothing magical about it.
I've been told twice how the 186P motor in our EH is a HP motor, and how good they are compared to an ordinary 186. I know it isn't.
It's an legend that won't go away.
I have an "expert" at work who has told me about how he put a HP motor in his LC Torana because of the thicker bore, steel crankshaft, stronger rods and everything else. He said it went so much harder than the 186. He also said he put triples, YT head and a cam in the HP motor. But it went better because it was a HP block.
I've told him the truth, including the fact that the HP is probably the weakest six cylinder block because the casting web at the bottom of the block bracing the bottom bellhousing bolts is smallest on a HP and EH 149 motor. Stand a HP, 186, 202, blue/black side by side and compare them, you will see the the web get bigger as the motors get younger.
I always thought the 186P was HK. Now I know it isn't.

Just to clarify, a Holden Red 6-cyl with a 186P prefix, signifies that is a regular (hi-comp) 186 for HK/HT/HG. It is the serial number 204841 places that it midway thru the HT model run. Had the engine number been say 186P123456 it would be an HK motor.

i had a jp block in my shop last month. (genuine xu-1 torana engine block for those that dont know)
first one i had seen apart, so was kinda expecting more strengthening ribs, or for it to be harder to hone or something - end result, nothing different to a "normal" 202 except the notching in the tops of the bores for the bigger valves.
