Glen,

The Webers do add the WOW! response from people. Can't count the number of people who stopped by to look at the FIA at the US Vintage Grand Prix and were in awe of the Webers. While I absolutely love them on the race car, I am not sure how well the IDA's would do on the street. They are not really happy under 4,000 rpms and they really love 5,000 rpms and above. If you were to use downdrafts the IDF's might be a better option for the sweet.

A Holley would work just as well too. What ever route you go will be the right one for you. Unless it is parked with the bonnet up, nobody knows what's underneath the bonnet anyways.

Good luck.

Cheers,

Jim

Hi Glen,

So if your donor engine is already EFI, the EFI needs to stay to be emission compliant.

I don't believe you can change back to carburettors, or change the camshaft profile, or compression ratio.

Correct, Gary. I think a "kerbside" noise test and a CO2 test are all the testing that is required if the engine is to standard/unmodified spec.
Can legally change the engine spec. (carbs/cam/heads) afterwards but would need to undergo the full IM240 test routine....hence the interest in piggybacking on the street rods freedoms. A lot of work to be done to achieve that though!

Cheers,
Glen

Jim, agreed ....Webers do add the WOW factor. If that does eventuate one day in the future, I agree - the IDFs would be more suitable. My high diff. ratio results in my gearing setup equating to a five speed gearbox with no first gear (2.92 diff and w/r Toploader)

Cheers!
Glen

OK, so Webers are on the "wish list", some time down the track. Got to get this car finished first, huh?

Nice Spring day here, so spent the afternoon out in the Cobra's garage with the door open ..... letting the sun shine in. Job in hand was mounting the battery in a "safe haven".
Took a bit of deliberation/procrastination but in the end, the seemingly obvious solution finally presented itself.

Turned out OK. Waiting on a thumb screw to secure the door, but otherwise, job done

Cheers!
Glen

Glen,

Nice work! Also, smartly placed on the passenger side to help offset the weight of the driver and improve balance.

Jim

The panel for the right hand side was easier/quicker to shape and install...

Progress update….

I’m currently working on fitting the steering lock. Should be an easy job …. except I need to remove the upper bearing to be able to fit the steering lock chopper plate (that’s the disc with holes for the lock pin to engage in).
With that removed, I need to then remove the dash panel so that the chopper plate can be slipped over the steering shaft. Dash removal isn’t a 5 minute job.
However, it’s progressing slowly, with a lot of other jobs ticked of as well, jobs too small to report on, but still essential.

Cheers!
Glen

For road registration purposes, I need an"eye-level" third brake light.
A machined aluminium housing, to be fitted with LEDs, was supplied but it looks way too modern and "techie" for my eye, so I found this nice Lucas light to use instead.

It exudes quality, and looks like it should be fitted on a Cobra

Just came in this week

Cheers!
Glen
