Australias version of the 396 Chev... In A Vauxhall,/ Torana. what about the Aussie 4 speed or the opal 4 speed, OMG... If you had a speco shifter on a 3 speed you were the talk of the town.
The Vauxhall does not share one bolt with a six cylinder LC or LJ Torana, yeah 1.1 litre HB Torana and 1.1 litre Torana but they different bodies and drive lines , these never had Opal gearboxes , only Holden 3 speed on the tree , 4 speed M20 or Trimatic .
Those flat oil filler caps are only used on rocker covers with 2 round holes on top,with the flat breather cap I guarantee the sump will eventually suck in & hit the crank. Early motors had a breather cap with walking stick where the PCV should be, then they went to breather cap with PCV, then the 202 went to flat breather cap with PCV & breather from middle of rocker cover to air cleaner. What happens when you suck on say a plastic coke bottle it starts to collapse & that’s what this is going to do.
First mod for a modfied high reving motor to allow it to breath and save oil gaskets from blowing out from internal pressure buildup, was to fit an oil catch can. Mandatory on track cars of the day. Fitted one to my REPCO crossflow headed FC Holden along with a large oil cooler and filter.
Yup, gotta vent that crankcase
Memories 👍🇦🇺
The Mighty 186........oh yeah.
Big block Holden 😂❤

Haha, back in the day I had the speco shifter.

If I remember correctly the H Q had a 202 not the 186 this looks like the 186 s with twin carbs out of the hot manaro
X2 had twin carbs while 186S had a single dual throat.
You are going to have problems without a breathable oil filler cap.
These and the Chev 6 engines don't have breathable caps. They have positive crankcase ventilation systems.

No breather .... hmmmmmm
Out of interest, what's the cap off? I sold this motor and put in a 173 with std carb and dizzy, to take it back to original.
