Are you trying to be authentic or do you just want the best fuel metering
system? As an engine builder I=E2=80=99ve used many different carbs in many
different applications. I use a gas analyzer to get mixture correct and
have found the Edelbrock (Carter) series easiest to tune. The 1403 500 CFM
is a great and responsive carb for anything under 250 hp. However, they
are definitely more susceptible to gas boiling, and we all know how cool it
is under a Tiger bonnet!
The 1848 is what I think came on a LAT1 kit and worked well on the 260.
Also the Holley 570 Street Avenger works well on moderately breathed-upon
engines and tolerates more thermal input but comes way too rich out of the
box. Plus they need a full setup (butterfly position, accept pump, bowl
cleaning and float setup) before running, as do all new Holleys. There is
also a Street Demon with poly bowls that is claimed to run much cooler but
at 625 CFM is much too big for a 260.
There are many new FI systems out there and to me the biggest advantage is
cool recirculated fuel, instant tuning and tolerance of the poor quality
swill that comes out of the pump. I am thinking that I will install the
Holley Sniper kit on one of my Tigers this winter as it is the least
invasive system I=E2=80=99ve seen so far.
