5.7 vs 6.1 coils

I am looking at some coil pack covers, such as the link attached, for my 5.7L. I can only find 6.1 covers, but the coil pack setup looks identical.. Does anyone know if the coil pack setup for the 6.1 is the same as the 5.7? This particular manufacturer states compatibility with 5.7, 6.1, 6.4L engines. Despite the difference in displacement, am i correct in assuming that the coil packs are the same and so the cover will be compatible? Did the coil pack setup change any between 2005-2010? Thanks!

The 5.7L and 6.1L have the same part numbers for ignition coils.

The 05 coil packs are different from the 06 and up coil packs. Yours has the coil over one plug, with a wire crossing over to a cylinder on the other side (Wasted Spark System), and the 06's and up have the coil over both plugs with no spark plug wires. The valve covers are different and the electrical plugs and pinouts are also different between the 05's and the 06's>. The bolt patterns of the actual valve covers of all the Hemi's is the same though, so the coil pack covers may work, especially if you use Taylor Shorty wires, and the coil covers bolt to the valve cover bolts. They probably won't work if they bolt to the coil mount bolts though since those bolt patterns between the two are different.

Thanks 90! i knew you'd respond to this, since you did the coil swap. Yeah i have the Shorty wire install, to get rid of the Wasted Spark. The fact that the manifold covers are the same is very helpful, as i imagine that's what the coil covers would mount on to. Thank you for your help! Now to just find a good cover set that isn't the $300 BT set. Haha

Thanks for the help man. I am looking into doing the 6.1 coil swap very soon anyway, and figured a pretty cover would really help the aesthetics. Also, when i was cleaning the dust off the valve cover and coil packs today, i thought a cover might help avoid that. Thanks!

My Post No. 9 of the attached thread shows my 05 Hemi LX with the Taylor Shorty's on it and then the late model setup. The complete changeover (valve covers, new late model electrical plugs and coils) will cost you around $500-600, depending on what kind of deal you can get. I bought the SOS high output coils and have them on my WK also. I used the 06 5.7 Hemi WK composite valve covers too.
