The whipple coolers only add about an inch in height, but they cost twice as much as most other chillers.

I think you'd be better off to just upgrade to 250 blowers and 1050 carbs for the same $$$ as the whipple chillers.

damn & i happen to know a guy w/ that setup who wants to part it out & go a different engine direction. Just no funds to go in that direction yet.

You have 250"s and dominators?

yup

So what happened to hawk. I picked up a 88 hawk gun this summer with 540/575 power with #3s and Borg warners. Stupid bullet proof boat. Remember them being "the" motors to run, then kina disappearing.

How did that combo run? any clue the recipe on the 575 engines?

Ran good in 2015.

My hawk 540s had been rebuilt at one time but were close to spec.

Found an old 80s Mag article stating the 540 aka hawk 600s made 590 hp

gm high po ls6 iron heads with bigger valves
9.1:1 compression ratio
cam that made peak power at 5600 rpm
eldebrock c454 intake


mine has the ls6 heads still but a weiland team g intake and different cams. I’m going to replace the heads with world Merlin 320cc

bow tie blocks Merlin heads full roller with girdles. 9/1TRW pistons. Dominators. Big heavy boat ran upper 70s in the right water.

here is what I KNOW I have now, no clue HP, but sound sweet and have not been able to water test yet...

Dart tall deck 548CI
10.0:1 (was told)
Callie cranks
Oliver billet rods
SRP Dome pistons
345CC Merlin heads
254/[email protected] flat tappet cams .595/.595 lift
Crane gold rockers
Trend pushrods
Brodix 4500 intakes
