Running a 74 18' challanger with built 455 and was pretty dissapointed after my first run this weekend. The motor runs great and strong at all rpms but boat dosnt really get moving till im almost 3/4 throttle and higher. Dosnt seem to be slipping but more like the thing is in first gear when it should be in 2nd or 3rd(i know they dont have gearbox just for comparison lol). I only was hitting 60ish on gps at almost wide open throttle on a 400hp motor. Im new to jet boats and finding out jaccuzzis arent the most fav pumps but was woundering if an impeller change, any kind of machine work, or if and energizer kit would be my best bet. I also want to add a place diverter but would like to wait to see if any kind of bowl swap might hlep me out first. I have tech know how and access to full machine shop. Thanks again for the input everyone, Josh

Just got my 455 olds back together and not sure what to set the timing at. Motor has mild cam, eldebrock manifold, bassett headers, stock k heads, mallory pointless distrib with msd blaster2 coil. Any help would be great. Thanks

have a new project and first set of water injected bassatt over transom headers....problem is they are rusted out and need to replace the sections where the water lines bolt up. Dose anyone know what size bungs to replace these with and also what kind of fitting is used to screw into them? Any input would be great. Thanks
