I had an oil line leaking, a place made a new one that was smaller inside never thought to check and I ruined my engine. 454 .030 Gen V. Here is the problem, I have a stroker kit for the engine which would make it a 489, but my block has to ground for clearance PIA. My motor was a 420 clone. My crank(cast) was turned down 10 and is ok it is a balanced assembly.
should I build the bottom back the same and just add a little bigger cam with changed firing order and 2.25 valves or how much would I gain by installing the stroker, a little bigger cam with the firing order changed and change my intake valves up to 2.25 from 2.19, then sell my balanced assembly. I just wonder what I would gain and would it be really worth it?

you know more than me on engine if you think about changing fire order... never heard about changing fire order before... curious to read other's answer...
