You'd want to make sure your alternator can keep up.

Hey Geoff,
That’s very interesting, I run a Hella U28 vacuum pump, but have had trouble with vacuum switches.

Cheers Phil.

Tech Torque Pre 1973 / Electric Brake Booster

Anyone know where I can source an electric brake booster and master cylinder system from? Front discs and rear drum. Looking to upgrade my brakes. What's everyone else running? I've heard the normal brake boosters don't have a very good pedal feel.

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.

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....

Yes. I know. Doesn't seem right.

4-barrel would be better but from the perspective of it being a second car that my wife drives, it's unnecessary. Cost is also a factor.

Happy wife...

Carb - Factory 2-barrel. No choke (doesn't help)
Manifold - Factory
Cam - Steel roller 1.5
Heads - Original factory. Machined. New hardened valve seats.
Compression - will need to find out.
Distributor - old school Autolite



It's a 347 but has a 2 barrel carb?

Thanks Glenn (and everyone) I really appreciate this.

I'm 2% of a mechanic and have been taking advice from my current/soon to be previous mechanic, so my knowledge isn't exhaustive.

Carb - Factory 2-barrel. No choke (doesn't help)
Manifold - Factory
Cam - Steel roller 1.5
Heads - Original factory. Machined. New hardened valve seats.
Compression - will need to find out.
Distributor - old school Autolite

The distributor needs the gear swapped for melonized to suit the cam, so I considered a new on altogether.

I'm also looking to replace the carb with the same but an electric choke.

It can be a lot of things . Your timing should be around 12 to 18 deg initial with the vacuum advance blocked .  The total timing should be 32 deg at around 3,000 rpm .  Getting these numbers  with a stock distributor won’t work .  All this depends on the engine mods .  More info please ,what carb and jetting , intake manifold ,heads ,cam and compression .

The timing is advanced and it is pinging. If it's not advanced it dies. My 'mechanic' indicated the dizzie but also said that it needs a 351 dizzie, which isn't obviously correct.

When it was stock 302 it had no overheating issue since putting in a large core radiator and fans.
