318/8 Speed Swap

8HP70 seems to be more attainable ($1000-$1500 price difference) opposed to the 8HP90 (call something a hellcat and price doubles)

most takeouts appear to be from 5.7 cars and trucks. obviously 2wd needed.
The Grail IMO, appears to be from a 6.4 car. It has a different torque converter than a 5.7 car. I can only assume higher stall than a 5.7 car. 6.4 makes more HP, has "bigger cam" etc.
RL261595AA / 68261595AA is the 6.4 challenger/ charger converter.
RL261258AA appears to be a 5.7 charger/challenger.

he 8speed has different gearing characteristics than say and old 727. It doesn't need a 4000 stall converter and 4.10 gears to get a 4000 lb car off the line.

I'm Hoping that the literal 1,000 lb difference doesn't hurt/affect the ability of an engine to idle in gear, w/o trying to grab. This would be the ultimate setback, but "chevelle guy" made no indication he swapped converters in his couple of videos.

Custom flexplate/flywheel is the biggest hurdle IMO to mating a SB, but its doable. I plan to document what i run into. flywheel is probably easiest way to do it, unless its TOO think, but I'd rather not hang 40 lbs of rotating mass onto my crankshaft. Custom flexplate with a spacer if needed is probably the route i'll go.

its perfect for a 5.7, or 6.4 swap. all OE stuff.
