Need Help with '97 Silverado
Since I sold the Hawk, I have been turning to nmy truck to fees my mod bug. I am a bit stymied by the powertrain though. It is a 5.7, but it has Spider Injection. I have found tuning software, but I am more concerned with the limits of this injection system. I was thinking of headers and maybe a whipple. I am getting the trans rebuilt right now and putting a mild converter in it too.
Has anyone successfully souped one of these up? Are there any aftermarket heads that will work on this truck? What generation block and heads is this, anyways - is it LT1 based?
Just looking for some advice. Thanks.

Eldebrock makes E-Tech heads that will work. They have 170 and 210 available. As far as I know there is no upgrade for the injection. JamesB is running 210 E-Tech heads and a Whipple on his Tahoe. He might be able to help you. I have a friend that wants me to build a 383 with E-Techs with a Whipple and nitrous. So this something I need to know to.

That is a very carefully tinkered-with L31 Marine EFI intake manifold. It's not installed yet but it will be this year. It has real injectors, will have functional EGR, will connect to the stock fuel lines, and it will literally plug in and bolt down in place of the stock CPI manifold.
This is no minor afternoon project. A great deal of time and money has been spent by many people collectively to bring this to reality. Our efforts are chronicled on the Pacific Performance Engineering Forum.

Wow, that is very impressive James! Are you going to run an aftermarket Engine Management or have you adapted to the stock PCM? I found that Tunercat sells tuning software for these trucks at a very reasonable price, so I am going to pick that up soon.
Thanks for all the info guys.
