Spraying A Stock Bottom End LT1 Thinking about spraying my 94 Z28, bolton LT1 with 94 thousand miles. Mods are in my sig. Question is how much can i spray with the stock fuelpump? i know i will require a tune, i already have a mailorder tune. I was thinking 75 the most a 100 and that is it. Do you think it is a good idea or will i be asking for problems?

The stock fuel pump and a original 21year old fuel pump are different things.
The mailorder tune is actually a threat to your ability to run a simple nitrous setup.
75-100 is not worth the effort.
Buy the safeties like window switch and timing retard, put a new fuel pump in it, might as well go Walbro and run a 150 shot.

About 10 years ago I had a 94 6 speed z28 with 150k on it. Shorty headers, cut out, cai and a dry kit 125 shot. Stock tune stock fuel pump. Only thing I did was change the plugs and gapped them correctly. Car made 380rwhp and 455rwtq and the air fuel on the dyno was perfect
