Brand new Gen 6, 7.4L long block that has 454 mag/502 hydraulic roller camshaft installed. Engine has 10 hours run time, std bore, crankshaft is std/std, block and heads were brand new. Engine can be finished out with intake and carb, or I have a MEFI 3 tune that can installed in your MPI induction. I also have brand new stock 7.4L camshaft if desired. Asking $ 3,000.00 for long block, will take worn engine in trade to reduce the cost. Internals are cast crankshaft, 3/8" rod bolts, hyperutectic flat top pistons, bearing clearances and ring gaps have been increased for marine usage. Great re-power candidate.
