    You can easily put together a system for around $600. My big problem is the high pressure in the lines. The early systems ran around 15psi and that is a good deal.

    Yall keep in mind you can have the a factory GM computer reprogrammed cheap enough, that is the key to getting it done for around $600

    Also, consider that to convert a GM 4.3 FI engine to a carb cost you easily $550. That is the way I am going but that is not the only way to do it. Fuel Injection is cool for a lot of reasons.

    Either way you are out about $1500-1700 to convert to a GM 4.3 with either option. That is just for the guys wanted to convert not just directly related to the current discussion of just fuel injected. Just thought some one might find it useful

    Parting in a junkyard with lower the project price.

    i had a chance to get a complete kit made by AFI for 250$, had to buy the temp sensor and it work fine.

    I love the injection on my jeep we have cold winter so it worth every penny (even if i would have paid 1000$).

    I realize this is an old thread, but something to consider for adapter material is Micarta, not the counter top stuff, the Micarta I am referring to is used by electric motor/generator repair/rewind shops. It is an excellent insulator, electrical and heat, can be shaped with common hand tools found in any garage, easily machined with a Dremel, hack saw, file, and tapped with regular taps. It is available in various thicknesses. Good luck!

    I made my adapter out of 1/2 plate steel, with a hole saw ,a grinder, and a die grinder. Works fine.

    Not much difference... Celsius and Fahrenheit are the same at -40 ... but maybe that was your point. <head scratch> :coffee:
