I have a 94 GM 5.0 Mercruiser

I have a 94 GM 5.0 Mercruiser that has a cracked block. A boat shop says they have a latemodel low hour Volvo 5.7 SX that will fit? Will a mercruiser GM intake manifold fit on a Volvo block / How can I find out what the motor really is and if it it is a Volvo engine. It looks like a GM what is the difference between a Volvo block and a GM block?
Any info will be appreciated Thanks
 
No difference. However; you s

No difference. However; you should check both engines for Vortec heads. Your 94 should have 12 bolts holding down the intake. A Vortec engine will have only 8. Physical dimensions and accessory mounts are the same on both engines. You will need a different intake for a Vortec.
