i was curious how big of a shot i can run w/ the mods in my sig. the lower end has about 100,000 miles on it now but all the new parts we just put on are in the sig. do i need to redo the lower end before i try to go w/ nitrous or can it handle it on a high milage lower end.

 

keep a stock timing setting and use the only up to the 100hp jets, keep fuel quality high even if it requires a octane booster.

 

Use the biggest shot you can get your hands on with as little fuel as possible, then buy a 350.

 

Dont use nitrous at all. We dont need car steroids to run good unlike the little ricers. Just my two cents.

 

your a jack &$$

 

B4Ctom1 is right, you should limit yourself to a 100 shot on a stock 305. Try use the best fuel + octane booster for happy healthy 1/4 mile runs.

If you are running a Stick Shift Car, then you might want to look into an RPM window switch. They provide best results at the 1/4 and the added saftey of having the N20 shut off before the REV limiter.
