I am going to spray my 94' this week.....what are the limitations with no programming?

I'd like to spray 150 or so..

Do you have an ignition box to control your rev limit and timing? If no, then I wouldn't spray more than a 100.

Start small around 75 and then work your way up to see what it will do at the track. A stock LT1 can handle 150 shot (wet kit). Also dont forget to change your spark plugs.

Things that are nice to have are a ign. box 2 heat range colder plugs , fuel pump for anything over a 100 shot. Window switch for M6 cars. IMO pulling timing on a 150 shot is not really needed.

what they all said,and yes i do recommend pulling timing on a 150 shot if you use pump gas.

if you run good fuel,have a good fuel system,and a strong ignition system,you can run 150 without pulling timing. pump gas and not pulling timing is a recipe for disastor.

i ran a 175 shot on a stock longblock for a full season with no problems,pulled 2-4 degree's depending on weather with good fuel.
