But Mount Glorious/Nebo is already a massive Nurburgring style track! (You just have to go there in the middle of the night)

Sounds awesome mate! What's your diff ratio? Seems pretty good.

Just a FYI; the stock mechanical fuel pump has never been a problem on my hot 4k with twin 42's.

My mate has a 4k sierra which his wife drives, air filter is poking out of the bonnet. Must be a common problem

If you want to drive around in a matte black ke35, paint it matte black! If you want to drive around in factory red with-a-few-touchups ke35, touch it up! If you don't want to drive around in a ke35 at all, sell it!

Vacuum leaks usually make it very hard to hold an idle but when you open the throttle it will rev fine, He says he has the opposite problem. Float level is a real possibility along with incorrect jets. Can you describe in greater detail what happens when you open the throttle too fast? If it stalls a little at low rpm, struggles and then climbs its probably too rich. If it quickly climbs a little but then cuts off at higher rpm then it is probably too lean. Since it revs fine when you open the throttle slowly i think it is jetted incorrectly and perhaps you should take philbeys advice.
