Hi guys, sorry if this has been asked and answered before - I'm sure it has - but couldn't find it without spending another hour searching...
My brother and I have a 63 Polara 500 with a 63 Superstock MW 426, which has been in there since the 80's we think. We had it rebuilt back in 2005 shortly after we bought the car and since then it's been pretty reliable, especially for a MW 'on the street'.
Since last summer though, it's started playing up; running like it's on less than eight and now not idling when it does feel like all cyl's are firing.
We've gone through the ignition system and stopped short of replacing the distributor. We have bought a new one as part of a kit from Firecore, and that was going to be the next step, but as it's running quite smooth now, but just not idling, we're now wondering whether the original Carter 3447s need a bit of work.
We would like to keep the original carbs but while we formulate a plan to get them restored/rebuilt (not than many AFB experts over here in the UK!), we're thinking of getting a couple of Edelbrocks if we can get the right part number of one that's a straight-swap. Ideally we'd like to keep the choke, throttle linkages and fuel feeds the same, as ours is all stock.
I have read on here that to fit an Eddy 1405, part of the carb's linkage needs to be trimmed to clear the MW's inlet. Apart from that, I'm not aware of any other fitment issues, or even if the 1405 is the right model?
Can anyone suggest which model will fit as a straight-swap, if any?
Thanks, Rob & Stu
