[Healeys] Webers, dellortos

[Wilko2]

Great post Derek.

I've been reading and compiling anecdotal evidence for years and though I
haven't yet run my car I have a hypothesis that I'd sure like to prove once I
finally get around to running my car.

That is very specific info on your carbs.

How is the rest of your engine? Overbored? Compression? Valves? Cam? Exhaust?

I'm still working a few hours a year for the last 15 years on my build.

Bored .030 over.
Schneider 2860 grind cam. (.425 lift, 260 degrees)
stock or works style tubular exhaust.
Australian style Redline short intake manifold like Chris Dimmock's
stock sized valves.
Polished mildly ported head

Are you just racing yours and how does it act around town?

Thanks,
Rick
