C & L, just a guess but was the cam removed/replaced at all?
It sound to me like cam/valve timing may be off causing a low rpm rush
at breathlessness @ hi rpm.
I drove a 240Z with a 28ZX engine for some time and accelleration was
great but top speed was abysmal.
Cam timing nowhere near correct, from memory cam advanced by several
teeth.

Subject: Not enough power
We got the '64 1600 on the road, disintegrating rear and all. A big
THANKS to
all the people who have given us help throughout the engine swap &
troubleshooting subsequent problems; this group and Datsun & Clymer
manuals
are pretty much all we have to go by! With that in mind, we are
facing
another problem. The Roadster has pretty decent acceleration through
1st &
2nd, but gets sluggish in higher gears/at higher speeds. The engine
also
backfires occasionally on acceleration. Any ideas on what we need to
look for
and correct are as always greatly appreciated!
Thanks in advance!
