Well im getting ready to put my new lt4 engine in my car.Its a stock one(330hp) with all the bolts ons(see sig).Add to this a tune and a asp 23% underdrive damper.

Im hoping for around 350whp.

Do i need some 30lb injector or my stocker are gonna be fine?

Thanks

 

If this is the factory crate LT4 you have referred to in previous posts, then it has 28#, so 30# would be an insignificant change.

No car needs bigger injectors if all you have is bolt ons.

You're also not going to see anywhere near 350RWHP. LT4 vettes make around that with bolt ons and a cam.

 

Yep its a crate engine but it doesnt come with injector.So right now all i have is the stock lt1 one wich are smaller then 28lbs.

So i guess some 30lbs would be good...right?

 

30# would be fine, but probably not on your stock LT1 tune.

Since you have to buy injectors anyway, you might consider going a little bigger to accommodate possible future mods.

 

Yes i finally decide to order a tune from madz28 since it will be needed no mather what

And i think that 30 or 32 would be ok because the reason i will be running the engine in is stock form is to have a fun and reliable ride for a couple of years.

 

I finally bought some 32lbs,i got them brand new for a very fair price.

It will be more then enough for the setup and will give me a little room for improving later
