I have worked with a lean condition just above idle and got it better by opening the idle feed up but it still isn't great and with the carb being a little small for this motor. I have considered EFI to be able to tune it better and maybe make it have better street manours.
1-So how would the Holley HP # 559-810 kit withe 36#injectors work in this application?
2-Would sequential be the way to go?
3-What is the best way to get Cam, Crank sensors, a dual sync or crank wheel
4-How well will the Holley manifold fit the dart pro 1 215 cc heads?
5-Has anyone used a LS1 fuel pump/sump in a first gen camaro?
Thanks Riley
