Tuning day all day today, started the day with a sweet offroad race jeep from a long time friend of mine, simple cammed 5.3 setup on a Holley terminator, ended the day with a badass 65 nova SBC with a procharger on a Holley, fought a lot of issues with it and still aren’t done but made a lot of progress, iron out the small things and get it back on the rollers soon
