548 efi bbc-730 hp
I am selling the 548 EFI motor I built two years ago. Motor available as drop in complete with accessories and exhaust or long block with EFI and intake components. Fuel and oil systems optionally available (currently not installed on motor). Motor has ~50 hours on it. Was never on dyno but speeds achieved in boat support HP estimates. The bad: Last run of last season, engine spun a rod bearing at sub 3000 rpm speeds and was immediately shut off (was actually during getting on plane for first time of day). Never lost oil pressure. I have invested over 21k in parts alone. Great deal for someone who is willing to fix a rod bearing to save ~50% of the cost of these components new.
Many photos available by request. Please send me a PM with your contact information for questions. All prices OBO. Not willing to split components unless all respective pieces spoken for with deposit.

Long Block with Exhaust and Accessories: $13k

I hope it isn't around that long! Haha. But I could be easily tempted if it is. You know I love a good science project. I need to get moving on that plenum shout design on that 500 intake.
