Its a very good plug mate so if you can put up with the lumpy start its worth it, alot of people go for c59`s but i`ve been told that there not that good for a 330/350 brake cossie, more a 220 brake rst engine kind of plug

I use 57's in my 200bhp rst aswell.
Use platinum tipped Motorcraft PP8's in my cossie, running similar spec as you.
