Hello, I am new to this forum and am hoping for a little help.
I am wondering if anyone has tried to install tripple HD6s on a left hand drive 3ooo?
I have been collecting bits for a while now to install on my car (57 100-6 w/3000 motor). I mocked-up the whole thing on a spare head on the bench. I was going to use stock tri-carb manifolds enlarged for 1 3/4 carbs but I ended up buying a set from Denis Welch. When I tried to install them I found the rear carb will not clear the steering column.
I realise the HDs (& all other semi-downdraft carbs I have) are built for 30 degree semi-downdraft. But the stock manifolds and the Denis Welch ones actually mount the carb at 25 deg. (which means the float chamber is 5 deg from vertical).
My solution was to mill the carb mounting surface at 32 deg, redrill & helicoil the carb studs at the new angle, and shave the head mounting surface of the manifold 1 degree. This mounts the carb at 33 deg semi-downdraft. With this rework I was able to get the rear carb in but I have only got about .200 clearance between the bottom of the car abd the steering column.
Now, after all the above, my burning question is: How much clearance is really needed? Has anyone attempted this on a left hand drive car?
I welcome all comments - my first race of the season is only a week away and I am finshing up the installation and hope to have it drivein this weekend so I can start making needles & fine tuning.
Thanks in advance
