Ok Im building a 383 and will be spraying a 300shot and just trying to get everything right. With the 3.75 stroke, 5.7 rods and a -5cc flat top heres my SCR and DCR this is with a 56cc head and .039 head gasket, .30 bore and block zero decked. Just wanted to know if they both are in a safe range for the amount of nitrous Im going to be running or do I need to bump them up a little bit?

SCR 12:3:1
DCR 8:5:1
