This late-70’s Winnebago RV came from the factory with a 440 ci V8 however the mechanics from Fuel Injection Sucks YouTube channel spent the summer increasing the power with some creative surgery. They replaced tired old big-block and factory transmission with a turbocharged 6.0 L LSx V8 and a 4L80E four-speed automatic transmission. Watch the team breath new life into the old RV below (full playlist below).
