4a-ge 16v internals

[kingcorolla]

first ill comfirm all this...
BLUETOP- TVIS, bigport, 3 rib block, 40mm big-end. 18mm gudgeon, NO squirters on rods.
RED/BLACK TOP- TVIS, bigport, 7 rib block, 42mm big-end. 20mm gudgeon, YES squirters on rods
both have same compression.
Now ive sed this before but i need some answers.

brought a 16v "bluetop" that apparently had wrong cam covers, (red/black)
then i noticed it had squirters on the rods... hmmm. Red/black top rods have squirters but 42mm big-end, so therefore must have red/blacktop crank. (yet havent confirmed this due to no vernier calipers but its logical.)
The only thing that is stopping this from being a red/black top so far is it has 3 ribs on block..?
is this possible?? to just switch between 3 - 7 blocks on 16v engines?

this is starting to drive me crazy since i was so close to ordering TRD shells for BLUETOP!!

by the way, they both got big-port and TVIS.

measure the crank
its possible to swap the cranks around.
it could be an aw11 s/c engine, which would mean 42mm crank. not sure if they are 3 rib or 7 rib though.
also early redtop tvis didnt have squirters nor it seems did gtv spev engine.
they all had the 42mm crank though
