engine cutting out down track after in 3rd gear!

Ok question guys... will the vac advance work at WOT? Reason I'm asking is bc when I raced it I only had 14 deg at idle. And when I pulled my vac hose off the dizzy it was only pulling 20 max with the limiters I had in it. I think I was going all the way down the track with only 20 deg timing.

Vacuum advance works with vacuum...at WOT there is very little vacuum...so the vacuum advance is not adding any advance to the distributor...vacuum advance is used while cruising a part throttle (high vacuum) to add more timing not at WOT....In fact at the track I would disconnect the hose and plug it at the carb..

check your timing with a timing light with the vacuum advance disconnected and plugged....as you rev up engine you should see the timing advance on the damper..
