How risky is running a 75 wet shot on a LT1 auto with 114k miles? I'm thinking about spraying but i dont wanna blow my motor any time soon so that's why i'm asking. I know with bigger shots you need to retard timing, but what about on a 75 shot? I understand alot of the problems end up with the tranny, i just got mine rebuilt for $1800 a couple months ago so if my tranny goes again i'm gonna be really pissed. What steps could i take to make sure i dont screw my tranny with the spray? Any help would be appreciated.

 

a window switch will cut the juice before the shifts

 

I have been spraying 100hp shot for awhile with my 140K motor. Make sure everything is in working order....
