Hello this is my first post on the forum, been lurking for a while and figured I would finally join . At the beginning of the summer I bought my first jet boat , 79 mach 1 ,bbf, split bowl , droop snoot. Diverter and all done by mpd. Ran 69 with a tired mild 460. Had a forged 557 with scj heads in the garage that I put in it and now I'm looking for some kind of tunnel . Or rogers to put my 557 into. Engine is dyno'd at 618hp 600tq. If anyone has any info on another boat or hull please let me know.
