Ive been seeing where people are putting them in their LT1s. Is this an alternative to SVO #30? Thanks

 

Nothing really. They are rated a touch bigger, but in reality to get that rating they are run at a higher fuel pressure.

For the price, SVO 30s cant be beat.

 

I bought LS1 injectors because they were cheap (50 bucks) and they're a good replacement for a bolt-on LT1 car that has injectors that are starting to show their age. Power adder or heads & cam cars should definitely consider something bigger. Like atljar said, they're rated higher at a higher fuel pressure. If you up the LT1 injectors up to 58 psi you'll get the same thing- which is another way to increase your injector's capacity without spending a lot of money.

 

the stock lt1 fuel injectors are rated at 24lb/hr. that's the rating with the lt1 stock fuel pump pumping at the stock rate. the ls1 injectors are set to 28.8, but they use a higher pressure fuel system. so no, without aftermarket pumps (t-rex, vortech, slp, whatever else) you're looking at maybe a 25lb injector. but...with the aftermarket pumps those injectors can handle about 500Fwhp or more.
