[bmw] Holly 4 bbl on big 6, was Re: EI questions & suggestions.

[jkerouac <jkerouac@xxxxxxxxxxxxx>]

Gregory,
         For a carburetor, I recall there is a Holly 4 bbl that was a 
common conversion, possibly around 450cfm?  Anyone on the digest know 
more about this?
    The Mallory coil model is called the Voltmaster.  There is also a 
Racemaster for sustained high RPM operation.
The NGK wires I used had 5 straight plug connectors and one angled one.  
The angled one was just right for plug number 6.  Any set that fits will 
be ok.
Great pictures, looks like a sweet 5'er.  That front spoiler 
w/integrated turn signals gives a unique look to the car but seems too 
rare to go vintage racing with.  If you  have those pics on a website, 
please post the link for others to see car you're working on.  With euro 
bumpers, the spoilers, and //M striping all around it really is sweet 
looking.

Barry
