Top end response

[Rich Kinsley <rlkinsley@xxxxxxxxx>]

I have been thinking about my top end performance. I have improved leaps 
and bounds in my ET's but my top-end is frozen around 70mph in the 
1/8th. It almost feels like a governor. I'm thinking I may have fuel 
delivery issues at sustained WOT. I know I have plenty of fuel available 
with my new 3/8's lines and the macho Holley blue 110gph electric pump. 
So I'm thinking that since the carbs are bumped up rich a couple stages 
maybe I should put in the larger needle and seats and high perf accel 
pumps. I may be lacking in flow capacity at sustained top-end. The accel 
pumps have larger nozzles currently but I feel it may need more volume 
also for the initial launch. I've ordered the Edelbrock #1980 
needle/seat assy ($11ea local) and the #1982 Hi-perf accel pump plunger 
assy ($14ea local). I'll try that out this season and see if it's the 
key to the top-end.

I was kinda wondering before if my Engine Dynamics 9&1/2" 3000 stall 
converter was slipping. In retrospect I think fuel delivery is more 
likely. 

What are your thoughts?
