im building a street strip car, limited driving, its a 350 bored .030 over dart iron eagle 215s, 10:1 static comp, cam is solid roller .501 lift cant recall duration, ne way its a stock distributor and the car has problems idling in gear and lack of power up top, car idles round 600 rpm. wont idle in any gear for more then 10 seconds, no top end power, weak spark, is the dizzy the cause? if not can ne 1 point me in the rite direction

 

Carb, right? Can we assume you set the timing like stock?

You can make it work by setting the timing with the RPMs up around 3000, set to 34-36 degrees. You might get some starter kick-back, and fuel economy cruising on the highway won't be very good. But, it should run fine at the track.

Or, get a distributor with vacuum and mechanical advance built into it, with vacuum disconnected and RPMs up high enough that there isn't any more mechanical advance, and set the timing to 34-36 degrees. Then hook the vacuum advance back up and set idle speed (in gear, park brake on, wheels blocked).

All this assuming you are running a carb.
