mods for boat

[Gregsn2toys]

Ok, I became an owner of no other then a '94 grand marquis, nto exactly grandpa's car but close. I fell into it for a price one couldnt refuse. Its sound now, after tearing down the motor and putting it back in. Word of advice, keep the coolant fresh in your engines. The front freeze plug rusted out of this one, under the chain cover and filled the crankcase with water. Its done, running, and drives. Heres my gripe. Ford has yet to make an Impala killer, and I have this one here. Looking to dial up te power on this. I plan on redoing the exhaust from the cat back, with dual Rav'n's, and 2.25" plumbing to keep some peacefullness to the volume, along with a crossover. Any suggestions as far as swaps, mods, etc.
