Do you happen to have the cam specs?

This agrees with another guy I talked with.  He open tracks a '68 Mustang

with a 351C and he replaced a Performer with the FPP unit.  He said it

made a big difference.

I'm waiting with baited breath.  The 2V heads have a much nicer exhaust

port than the 4V heads.  The Aussie heads are very similar to the U.S. 2V

heads except they have the superior closed combustion chamber of the early

4V heads.



The downside to 2V heads is a lack of performance intakes.  The performance

intake market is primarily geared towards the 4V heads.  I don't know of

any high rise single or dual planes for the 2V heads.  There are low

rise dual planes (Edelbrock Performer 2V) and single planes (Weiand

X-celerator) though and I've heard of some 2V intakes from Australia.

Offenhauser probably has something too.
