Default pair of 383's 400 hp 460 lb/tq for Sale

I have finally decided to post this nice pair of SBC that i built for myself last year for my Wellcraft Nova that ended up selling to a great guy here in OSO when i found my beautiful 272 sr1 which is running great with 454's with no issues after 100 hours of use, so i didnt want to swap engines,I just kept the 383's for a while just in case i needed them and I decided to sell them now,ALL NEW PARTS have over $20,000 invested in them Including all accesories P/S pump,New Stainless Marine Manifolds and Risers( Risers bought them used but pressure checked by SM) Marine MSD ignition Box(blue ones)MSD distributor,MSD Hi Performance Blaster Coil ,Bob Madara designed and provided the Hydraulic Roller Cam and also the PBM lifters to go with it) Block is reconditioned .30 over.
built by Power Source Distributor in Miami(30 years of experience) and also Dyno tuned by Mesa Balancing Racing ( Laz Mesa).Engines are very conservative, and were built looking for reliability.

This is a great buy. I have $15000 in my 355's with Mercruiser OEM CI Exhaust!!

The way Diego built these motors they would make a great pair of drop ins for a Cruiser with tired BBC's or a serious replacement for tired 350 Mags in a 292 FasTech or something similar.

These motors were built for the long run and will give some one years of reliable high performance service.
