Running Out Of RPMs

[chuck ciaffone <chuckc@ibm.net>]

Hi Y'all,

Now that the engine is broken in and the gear box
is running well, I have been playing around at higher
speeds. I can run close to the red line going up thru
the gears, but once in 4th or 5th, I can't seem to
get much above 4000 rpm. Now I admit, I'm using
a stock 1275 with 2 SUs, but it seems like I ought to
be able to get the revs up more. Seems to just run out
of rpms. Without going to a new cam or a Weber, what
might I do to get more revs? New fuel pump?
