get a computer and harness from junkyard...  way to much work and impossible to use jeep computer.... you could use some of the jeep harness but all the splicing would make you pull your hair out,

cool ty kinda what i figured

I got the computer out of an 88k5 TBI.

the motor is otta a 92 suburban the only other prob im coming across right now is lvling the front end after motor is in. i have the 2.5' coil spacer lift in right now. gotta figure out how big a spring to put in 

[xjs3667]

Try looking at coils out of a 95ish style dodge ram 4x4... I think they will work right up your ally for it   do you have a measurement of around what they need to be?   I got a 97 ram, out front right now I could give ya the measure. of it how it sits, but im pretty sure them springs would work good for ya, and would definitely hold the added weight of the sbc.

i dont have a measurement yet been getting all parts i need to finish the overhaul on the motor. Other problems have sent money else where so has slowed the project down greatly.  Also does anyone know a good place that can redo my drive angle up front or anyone that can do it would be greatly appreciated.

don't worry about your springs yet, believe it or not the SBC isn't much heavier than the 4.0
