Magnum sedan engines?
 

Can anyone tell me what make these engines are? The boat is a 1972. Here is a picture of them. Sorry in advanced for not having a great picture. I am not near the boat at them moment and this is the best picture I have at the moment.

chevy. they are even chevy orange.....

Thanks for the reply. I know I am asking for a lot but any idea what model? Was12

the block number should give you a start. As for a mfg like merc, volvo etc.. Its not going to happen. The only definitive way you will find out whats in them is to take them apart. More than likely they are 350 sbc's

Thanks for the info. Was12

The drives look volvo, so if the motor started volvo for 1972 theonly two v8's listed are the AQ200a and the AQ210a

They look like Chevy & most likely they are Crusader 350cu 300hp with Volvo drives as many Magnum sports & sedans had that powertrain. The main difference I see is your exhaust manifolds have been replaced with aftermarket ones. The pic I'm posting are what my sedans looked like when it was new.

Here are the engines he has, they look a little ruff..:eek: They could be Crusaders marine a long time ago..
