Update , Getting all the parts to complete the Project so has I hope 2016 summer it will see the water !

Those were some king kong trim tabs on that sucker!! Saw a cherry malibu corvette edition few months ago (the cheap 50k when new version. A new vette back then was 36k) remember that was before the vortec motors. Way before the ls motors. And down here in pick up truck land used whipple kits for the ls truck motors are cheaper than a used set of catalyst manifolds from a ctsv or zo6 powered wake boat.
I heard the optispark was born about the same time putting the engine under the windshield became all the rage . still need a specially prepped rotating assy to reliably live past 5500 and 350hp wfo on the 5.7 lt. Glad you went ls

Thanks for the info , I think my Lq4 6.0 LS should do pretty good N/A at first and then will see what happens.
