Some headers combined with AFR hi performance alu heads will do it.
but will cost you about 3500.
combined with a bit of ECM tune would be perfect.
but there arent to much guys who knows how to.
Dit some mods myself but costs are about same as a new block
But I always take another path.
I did put on a pair of HITEK headers, and a procharger and reached a 14,5 knot increase in topspeed.
Power is around 490HP out of this small block and is max reliable for this engine block.
I have a DP-SM drive who can handle this power.
On a stock mercruiser alpha or bravo3 drive its a matter of waiting they fail
with another crank and pistons it could be 540HP /5200rpm
