Nice work. How far is the engine offset to the left? Looks like a couple of inches

Trans tunnel/diff are all offset to pass side
Graig (AP) may chime in here with a more "Technical" answer

There is an offset for the engine /gear box...but it is certainly part of the design.
Many sports cars/performance cars are made with a similar offset ( Including original Cobras).
It helps get all of the "cross weights" correct.
It assumes that in high performance situations there will be one driver/no passenger...and it makes a much better balance race car.
Don't worry...it doesn't mean it's not safe with two people on board.
Cheers,
Warren

I didn't know the originals were offset. Learning something every day about these cars. ERA definitely offset the drivetrain to the passenger side.

Yes...quite right.
The offset not only gives a better balance...making room for the drivers will always be helped with that offset.
Cheers,

Back to the Holley EFI, do you need to pass an emissions test? It looks sensational.

Yes..............will it?
Ill put the best (cats) I can in, go and have a good tune (the engine  ) Will take it to a mechanic/exhaust specialists who can perform 4/5 gas test and see what happens. There's always running E85
Time will till

With the offset it would also add weight to the left as the torque effect wants to lift the left side up. Does that mean in a left hand drive the offset is also on the left.

The engine offset to passenger side is around 25 to 30mm depending on drivetrain fitted.
Offsetting the drivetrain gives us 3 main advantages, which you guys have already touched on:
- More cockpit space for the driver, especially footbox width for drivers feet.
- Better cross-weight balance
- Reduces torque effect of engine on handing

JD, very astute of you.  Offsetting the drivetrain works best on RHD, you just can't get all the benefits with LHD. |

I believe the posts under Guye's Pace build include the reference to his use of HSV cats as high quality convertors. He had the race mob building his lovely looking exhaust system!
Anyway a good tune by a specialist and you should romp it in as it is an older emissions standard that was set - pre-AU falcon times I thought.
Best of luck!

Quite right, Slowy.
Muddy, HSV cats are available for rental, custom made to fit pace headers and under car setup. PM for details
