I have a V5 7GXIDP 4012032888 Chaparral 265 551 and I need to replace the volvo penta inboard 400HP engine with fuel pump. I can ship my core. Do you have this engine for sale?

These 5.7 GXI engines are no longer available from Volvo Penta.  GM, who used to make the blocks, is no longer
manufacturing them.  I would need to know the serial number of your engine before I could quote exact
part numbers.  I show the maximum on these 5.7 GXi engines were 320 HP, but with the serial number
I can confirm.
 
So there are three options:
 
1)       As of today, I can still get a longblock for this engine.  Once the longblocks are sold then there will be no new ones.
The cost for the longblock (engine block with innards and head) is about $4,400.
 
2)      Volvo Penta does offer a V8-380 –C which is a 6.0L engine (with catalytic ), but you have to purchase a complete package
with outdrive.  Total cost is in the $30,000 range.
 
3)       You can purchase what is called a Crate engine from an aftermarket re-builder.  These engines are getting hard to get
but if you can find them they are in the $10,000 range.
 
4)      The final option and is probably the best is to replace the engine with a 383 MPI Mercruiser (350HP).  Mercruiser takes
a 5.7 (or a 6.2)  and bores and strokes it out to the 383 MPI.   Mercruiser makes their own 5.7 block based on the GM.
Everything fits in existing engine space and all the wires and transmission (or outdrive) connects up.  Around $13,500 for
a complete engine ready drop in.
