To Vacuum Advance or Not to Vacuum Advance
Ok, getting close to completing my engine swap - final pieces
The details: 408 stroker - 10.5 to 1 Compression, Holley 750, Comp xe285hl cam. Built 904 with a 3500 Stall
The distributor is a MSD 8388
Usage - Street bruiser (will see the drag strip and some autocross) - don't really care about gas mileage
I can not really find anything - just that Vacuum Advance helps fuel economy. And some comments that performance engines usually do not run vacuum advance
On my previous motor (not very strong - just over cam'd) - I took it for dyno tuning - the place removed the Vacuum horn right away. Stating it was a limiting factor
Hence I am a little confused. What are the pros/cons to run vacuum advance on a performance engine
