So the motor went in my 2004 searay 215 and I’m thinking of dropping a 350 in there. But what would be different? Would my intake bolt up? Also what about tuning?
Your 305 was multi point injected, The only difference, at a quick glance through the parts manuals, is the ECU. The fuel rail and injectors, the throttle body and the rest of the electrics are the same.
Those parts are going to be spendy to swap. I would go with another 305 long block unless you have a complete 350 donor. A user on here just recently was trying to do a similar swap and tried many ECUs but last I read couldn't find one that worked.
