Cis 3.0 vs 3.3
 

Just wanted to once again thank all the people who have been helping by lending their knowledge and offering assistance

So my latest dilemma is I have two cis systems a 3.3 that came out of a running and my original 3.0l cis systems what one should I use? I leaning towards using the 3.3 I have gone through both of them and the only difference I can see is the 3.0 has a solenoid to nudge the sensor plate to assist during start up …

. so where does this solenoid get its signal to engage ?

also both fuel distributors internally and externally appear to be the same other than the part #s

I am assuming I can use the 3.3 cis as it has the automatic advance rather than the solenoid advance

Other than that they should be the same correct??? http://forums.pelicanparts.com/uploa...1587406294.jpg

I'd use the 3.3L version. The FD has more capacity and the WUR will enrich on boost. The air meter assembly is also more primitive on the 3.0L version.

Thanks i just need to hear it from someone that the two were interchangeable .
