How many Cranking Amps?

[beaverliner]

Hi Everyone, I have a big block 1999 454 OMC Cobra (7.4L). I am planning to buy a booster pack to keep in the boat as an added "insurance" even though I have dual batteries with a switch... How many amps should I get in the booster pack to be able to start this engine?
Thanks
J
