well im planning on doing an lt1 swap somewhere here in the near future but for now i want to throw a shot of nitrous to the lil 305 and see what she'll do,so i got a few questions such as what size shot for a 305 tpi? wet or dry shot?will i need to retard my timing and get colder spark plugs?and who has what i need for the best price?thanks in advance,joe

 

For a 305 i ran a 100 shot NX (rwhp) on a 305 and it did fine for about 2 bottles....lol I would say a 75 nx or a 100 nos jet set up. the NX is rated at the wheels and nos is at the crank. I would also run a wet system since you only have 19 lbs injecters. As far as plugs i would go one step colder and rule of thumb with timing is take a degree or two of timing out for ever 50hp you add. hope this helps.
