I have a digital Ammeter that indicates my 5.2l v8 low compression mopar 318, when cold, can pull as much as 170 amps.
I do not know how many times a second it refreshes so the actual peak/inrush current 'could' be much higher.
When the engine is already warm the max I've seen it register is about 65 amps.
My fuel injected engine always starts quickly and a 12Ah AGM, the UB12120, common in many lead acid jumper packs, has no issues assisting the engine battery when I would run it too low.
Never tried a lithium jumperpack.
