Okay, I have a fresh rebuilt 305...

I am going to do a 100/125 shot on the new motor, I don't have the stock cam, I have a crane cam (unsure of grind).

Are there any mods I should do before I start spraying?

I would just supercharge the motor, but I don't see any superchargers within a reasonable price range and nitrous seems alittle better for me as I have alittle bit of a lead foot and I would really wear the motor out with a supercharger. As with nitrous I can just close the valve on the bottle and have to drive it like a grocery getter.

From research on the boards I've noticed I will need a colder plug, advance the timing a few degrees...and get some tires to put down all that extra power.

I've already taken care of the tires with BF Goodrich Comp T/A Drag Radials 255/50/16.

 

i saw that you said advance timing a few degrees. You need to retard the timing 1 degree for every 50hp of N2O.

 

Didn't even notice I said advance!
