Now’s the time to install our Headers. We have a set of silver powdercoated wet LS headers from Lightning. Because we decided on a (much maligned) carbureted application, these headers won’t need to have an O2 sensor provision that an EFI application would have. Follow along as we install the headers on the engine and install the water tree and lines to the thermostat housing.

LS MARINE ENGINE CONVERSION: GM LS 4.8, 5.3, 6.0, 6.2 Installing the Carburetor
This week we install the 650 CFM Quick Fuel Carburetor on our LS motor. We had many questions on why we chose to use a carburetor rather than EFI. We did so for a couple reasons. 1), its more cost effective and 2) we don’t have to run an O2 sensor. We’re using a 1″ carb spacer and 1″ extended length mounting studs with our application.

LS MARINE ENGINE CONVERSION: GM LS 4.8, 5.3, 6.0, 6.2 INSTALLING ENGINE TO JET DRIVE PTO & DRIVELINE ASSEMBLY
In the latest installment of its video-based series focused on converting a General Motor LS automotive engine for marine applications, the crew at Powerboat1.com tackles the next step in showing one of the possible combinations this powerplant could be used in.
Rick Bourns, the video host of Powerboat1.com and project and research leader for CP Performance. “Prepping this particular engine for say a Berkeley jet driven boat is a snap once we identify the matching components” .
PB1’s own Rick Bourns takes us through Identifying the different Styles of GM LS Crankshafts. The GM LS1, 2, and 3 series engines were offered in two different crankshaft end styles. The was based on what the intended use of truck or automobile might be. In this episode Rick shows us the correct Power Take-Off (PTO) and U-Joint Driveline Assembly that Hardin Marine has developed to make such a conversion a snap. With this type of detailed tech advise available these folks are turning these projects into true do- it-yourself types of projects
