Pair of Mercruiser 454/440hp Cyclones
 

Pulled these from a boat I parted out three years ago and stored them in my shop,
Was going to use them in my race boat but have decided to go with 540s.
They were running fine when I pulled them HOWEVER the camshafts in these
engines have been swapped out. I know stock cams had huge duration,that may be why they were replaced,they have what sounds like 365hp cams.
I opened them up to confirm condition and
they are very nice for 35 year old engines. They will need refreshing but it wont take much
Cylinder walls are in very good shape. Engines had good oil pressure when pulled.
I have all the accesories and hoses for both engines.
They came with Gil manifolds and dry pipes however I am keeping those
Video of them running just before I pulled them
Both engines with accesories ,intakes and carbs $5000
Both engines with accesories but no intake or carbs $4500
Both engines with no intakes no carbs and no accesories $4000
Both shortblocks only (no heads,no accesories,no intakes,no carbs) $3000
