what is unsafe about this and what kind of trouble will it give and will a 454 or 502 be a waste of money it has an olds now i plan on keeping the boat for awhile
well if it comes with an olds use it till it blows up. then see if it handles like you want. just my .02. just dont bring it up over 4500 rpm's cause that olds will blow quicker than shizzle...
