Merc 420 Cyclone engines

Because 700 hp is going to need stronger transmissions, larger engine and trans coolers$40K might be light.

Why would u need bigger trannies ???? the 8 plate BW C72 are easy good for 700 FPT so thats a lot and over 700 HP !

the coolers on the bellhousing should be the regular ones... so they are good too ( i have over 700 HP on them ! )...the trannie cooler i use a inline 12 inch one ! nothing special or expensive !

just sayin'

I'll disagree with youthere. My 630HP 540's puked 9 plate 72's twice before I had them done with the 1450 Huber setup's. They only had 602 lbs torque....

WOW...learn how to throttle...LOLOLOLOL

no, seriously... to make a 8 plate last.. u use the clutches from a chrysler tranny ( KEVLAR ) from the local autozone store.... i have to look up the #... but they are like 300+ bucks only.
Then u maschine the housing inside and fit 2 more in them . WUOLLA...now u have your HP 1000 TRANNY !

and mine had 8 plates..3 years no problem... now 10 plates...because the shift lever was bad.. so we did the hole thing !
