What timing for 83mm B18C, LS crank, 9.4:1 c/r, Portflow head, stock GSR cams
Hi guys,
My motor is getting assembled and will be getting dropped back in the car over the next couple of days. I'm gonna run it N/A until the car gets BAR certifieid. I'm debating whether I wanna run my stock P72, or if I wanna run my chipped P28 with a stock or lightly modded GSR map. I just needed to know where to set my timing with my setup. Like how much should I advance my whole timing map to make up for the increased bore size and lower CR? Also, will I be fine on stock GSR fuel maps, or should I richen it up a bit?
Thanks
