What safety mods you running, how old are the injectors and fuel pump, what size injectors.

General Answer: 150 shot

Reality: Is the car sound, I know the engine is, but what about the fuel system?

I know of cars running 200+ on stock shortblocks. On stock as cast heads though you will probably stop going faster after 150-175hp jets the heads wont flow enough let more than that really work.

One b-body I know of ported iron heads XE 224/236 200+80 and ran 10.9 at 122mph, motor had been seeing 200+ for YEARS

With your fuel system in good working order, you'll be able to run a 150 shot safely for quite a while. Just make sure you a/f is safe on a wideband before you start spraying the crap out of it. I've been running a 100 shot on my car for over a year and I only had one hiccup when it leaned out a little too much, but everything else has been fine.

It is a good rule of thumb to get a new in-tank pump (Racetronix/Walboro 255lph) and that'll be able to support any fuel you'll be needing for a 150 shot and up.

Just check and double check it all before you start spraying a lot, and your car will have many many bottles to be used in its future.

I have put about 15 bottles of 150 shots through my motor. It still loves the bottle, but I took it off for the time being, going to run the new H/C setup N/A for a while then throw the bottle back on.

Just listen to everyone when they say to make sure the fuel is up to par. I have all the safety requirements and that is most likely why I havent had any issues.
GL with the kit
