My Title description is not correct. I did not swamp engines just uped the power.

I used the same block numbers MATCH.

But I am sure they can read EDELBROCK on the cylinder heads and Sea Demon on the carb and know they did not come on a 330 engine.

There is know why without tearing the engine apart to know it was stroked to a 496. And so on.

If I left the 781 cast heads on I would not be asking this question.

Maybe I should get out my paint can and paint everything black!

many years ago a freind of my Dad's put a 200hp outboard on his bassboat and put the 150 cowling back on the motor. Everything looked like the 150 and people couldn't figure out why he was so much faster but he had an accident and the boat was destroyed. The Ins. Co. opened it up and measured the cylinders.......knowingly providing false info makes the contract null and void. (he didn't collect a dime!)

IMO: The savings in premiums just isn't worth the risk of not having coverage.

This is very interesting, If you swaped motors tell them!! However if you just did some really good maintence to the motor, no big deal. I kind of view it as like swapping props to get a few more mph, would you change everything for that.

I agree.

But, your obviously thinking about doing the unthinkable, just don't say we didn't warn you.
