hi everybody , this is more of first hand testing results sharing then a question thread so here we go ......few weeks ago I got set up with coil on plug ignition by Cal ,reasons .... LS1 coils will be around for years , stepping away from waste spark system was also part of my decision ,we all know that you can go fast with stock ignition , we also know that you will go fastERRRR with distributor set up , we know that because we know that anybody with stock ignition will have to gapp plugs realy tight like 0.022-25" to keep fireing them under high boost/load and distributor will let you open them up well.........I am reporting here that Cal's COP system will let you do same , last night got my first track test done ,did not do very fast passes since my 60' were in 1.8 range lounching at 5 PSI , idea was to test the ignition for the first time , car ran 10.5 at 128 MPH ,26/ 27 PSI on pump gas and Alky with plugs gapped at 0.035" hitting 6500 RPM and no PROBLEMO at all , more to come but so far I am one very happy customer ,thanks to Cal Hartline
