Nitrous on a stock lt1
Ok guys I’m looking to shoot 150 shot on a stock lt1 6 speed. I have a couple of questions.
#1 what ignition box are you guys using to pull timing on these cars now? I know that back in the days most guys used a Mallory 685.
#2 I’m looking at a nos plate kit but it uses a 58 tb can I run it with the stock tb or do I need to use the stock 58 tb.
#3 will I be ok with a 150 shot and the stock fuel pump or is a 255 walbro a must?
Also what kind of gains can I expect to see in a stock lt1 with a 150 shot.
Thanks

#1 I like MSD personally, and have a Digital 6.
#2 I would contact Holley and ask.
#3 I have seen 150 shots on a stock pump, but a fuel pressure safety switch is a must
A 150 shot from a system that does what is says, should add 150 (or close to) the wheels. 150 is about the limit for the stock bottom end, and as these cars are getting up in age, I would consider the mileage and actual condition of the engine before going straight to the max.
Can you give more detail about the car and it's upkeep? Has anything on the engine been replaced?
