5.7L (345 cu in) HEMI V8 Specific Topics
Well I don't know if I should put this in the 5.7 or 6.4 as I have a 5.7 hemi stroker I have built. However that is the issue, it will start on the first start attempt but it is super rough won't idle for long before dying and this is after the tuner has played with fueling and everything to try...
