Check the condition of the belts also. Look for cracks on the inside in particular. A broken belt can really wreck your day.

I think it would be more likely to be the alternator belt, rather than the steer belt. The steer belt is under very little load unless you are turning, whereas the alternator starts charging at a high level immediately on start to recover the charge lost while cranking, then reduces charge rate. That said, it would pay to check all belts. What is the car, what engine?

Offset grind and use small journal SBC 6" Carillo rods or similar.

XT and XW had them, but everything else 100%

And that's the great thing about a turbo

More than my old F350 requires

One comment, I doubt the Aussiespeed 4 barrel manifold will fit in a RHD F series. Brake master looks too close.

not home yet...

That was quick! I will try to get some photos when I get home today

I have a 300, it's in my '72 F350. Yes they are long and tall. I can take photos or measurements if anyone wants.

Or they were never fitted in the first place

Drive a modern turbo engine for evidence of what Slydog is talking about. Instant torque and a perfectly flat torque curve (plateau/table?) from about 1500 rpm (under stall speed) to 4 or 5 thousand rpm. Perfect drivability with great fuel economy, win win.
