i'm putting a stock ls3 long block into a 1975 standard non matching numbers coupe. looking for some great, dependable,compatible fuel ijectors to fit the stock fuel rail and intake that i'm buying separate pieces for. no complete stock intakes available in the country and no hard gm resupply date so i'm pieceing it together. yes more expensive, not incredibly so but still. stealership just that. i used fuel injector clinic before. was going to call them. any of you vendors,fellow posters suggestions will be taken under advisement. i always appriciate your guildance and help. even if i cant spell for s**t anymore. trust me its age related. the oldman.........

Pretty sure I still have the injectors that came with the Whipple I bought. Previous owner used them for about 500 miles and I went bigger on my install. Not stock, but not huge either if you are planning on more power.

I'm still running the Siemens injectors from a Whipple on my turbo car and they have been flawless, but I am at the limit on them. More than enough for NA.

Wouldn't normally recommend injectors on EBAY but the ones from this supplier have been confirmed as good by users on HPT.

You will have to change some orings and space the fuel rails.
