One just like this... http://store.summitracing.com/partdetail.asp?part=EDL-7525&autoview=sku
but for a smallblock 360 and with enough room for sick bastards like me that firewall clearance isn't an issue (53 Merc pickup) and want to run one of the HEI converted distributors like this one...
Someting that you can use either Eddies or Hollies if a thin adapter plate is needed to run one or the other thats no big deal but still remain low enough to clear the hood on a stock A-body. All for under 300 bucks.
