Thank you for the advice.
Are we better off replacing the motor with an engine GM still makes like the 350? Would the retrofit be a problem with the trany or other parts like the manifold if we did that?
Minus a possible gear reduction difference, the SBC will work with the existing transmissions.
However, you would be required to replace the exhaust system if you went from a BBC to the SBC.
When properly built, the GM 6.3L SBC (aka the 383 cu in) is an option..... but only when a Q/E is incorporated into the build.
In other words..... NO GM full dished pistons!
Seems like the HP was low for a 454. I had a Corvette with a 427 and i believe the HP was north of 400.
The higher horse power Automotive build is considerably different from that of the Marine build.
If an Automotive build is used, you will very likely have trouble.
We have a surveyor coming on Monday. But I didn't realize they did the motor also. I thought we would have to hire a mechanic as well.
Not all Marine surveyors do both structural and mechanical surveys. It sounds as though your surveyor does both.
If we need to replace the engine with a rebuilt, any idea what the cost would be to take it out and install a refurbished Engine?
Check with a reputable company such as Michigan Motors.
Thank you, Dave
