Has anyone attempted to use the stock exhaust manifolds that come with the 6.4L crate engine on an E body? Looks like these are basically shorty headers, 3" output.

Probably a longshot but I thought I'd ask. I'm going to fit the engine shortly before finishing body/paint.

Thanks...

Yup not even close. The Holley swap shorties fit great. Unfortunately, they don't make the long tubes anymore and in fact seem to be discontinuing a lot of the e-body Gen III hemi swap items.
