I think you're about to get some big bills.
So - if the dist gear is wrong for the cam, there's NO WAY it should have been assembled. DO NOT RUN IT until you have the right dist gear installed.
Pick your battles...
Measure the timing - just because it detonates, it doesn't mean it's too far advanced - running too rich or too lean may also cause it to ping. You need to MEASURE the timing and make changes because you can see a problem, not because you're throwing money at the dart board trying to replace everything until it stops overheating.

Was the carb re-jetted to suit the large capacity? If it's still jetted to suit a 5.0Ltr but it's now a 5.4L then it'll be too lean.

You need to get it tuned by someone who has all the right tools. I would get rid of the 2-barrell carb and manifold for a 4-barrell, your wife won't want to drive it when it's running like a POS any more than she will if it goes hard. Get it running well before worrying about your wife's level of enjoyment....

Hi Jiffy,

Thanks for this.

I've garaged the car and it's not being driven until the gear is changed. My ignorance and my mechanic to blame there.

The timing has been measured and is advanced. Your point re the carb is great as I assume this will affect temp, starting, and stalling. No choke on the carb compounds the issues again.

As a lower dollar solve, from replacing the manifold and carb with 4-barrel, I assume replacing the jets and adding an auto choke is fairly straightforward?

Thanks again for your and everyone's input, mate.
