Hi,
If you don't use Webers, do you need the access panel cut out in the shroud?
If you are looking at Pertronix..from personal experience I'd suggest a
123Ignition setup. With that you can select from a choice of different
advance curves which - as you are plainly going to be dealing with
cam/timing/mixture issues - can usefully complement work/adjustment in these
interlocking areas. (At least, I think so!!)

Joe,
Thanks for the additional information. The car will be LH drive & I am in a
position to modify the foot box area, but in the final analysis, this may
be
the deal breaker for Webers.
I am considering a loose replica (or "tribute") of the racing (not rally)
works cars. It would have a hardtop with vent, cowl air scoop, carb access
panel, modified grille work, etc. It will not be an exact copy of any one
specific car.
The mechanical specs. are intended to produce additional power (above BJ8
specs.) while still maintaining street drivability. The car will not be
road
raced. I envision the following:
capable of using premium pump fuel, therefore 10:1 compression maximum.
Bored out .060", although some have advised against this. Cam: slightly
hotter than a BJ8 cam. I have been told Elgin has a good grind which is
described
as something like 268 degree cam. Further investigation is required.
An exhaust header. I would anticipate a red line of approx 5500 to 6000.
Other Mods. would probably be limited to reliability items such as
lightened
&
balanced engine components (including flywheel, rods, pistons), Petronix
ignition & perhaps a roller rocker. Please feel free make suggestions.
I know from experience that Webers are great carbs, but was (am) concerned
about the challenge of tuning them, especially for good street drivability.
I
was anticipating needing to choke down the 45DCOE's with 32 to 36 main
ventures. I am hoping someone has a 3000 with specs. similar to the above
that
could provide their complete "jetting" specs. as a good starting point.
My belief is that properly setup Webers should be capable of producing a
street drivable engine with MPG comparable to the same engine with properly
set
up SU's.
The challenge lies in arriving at the correct setup & that can be a BIG
challange.

What is the spec. or your planned spec. of the engine?
How do you intend to use the car?
