I've got several relatively stock 258 powered rigs and each will eventually get a 4.0 #7120 head and some sort of 4.0 cam. The plan is also to add fuel injection to each one of them using factory 4.0 fuel injection stuff.
What donor vehicle do you guys recommend? One of the rigs is a T176 trans and the other a TF904, I plan on doing a front mounted CPS instead of the bellhousing style. Will the computer throw fault codes without the trans plugged in if the donor Jeep is automatic? Basically I need the computer to run the fuel pump, ignition and injection.
I've had a lot of experience in the past with the RENIX 4.0's however I'd like to stay away from EGR valves so 91-06?
