Why can't you do innercoolers???

The whipple coolers are pricey but only add an inch or less in height. Upping the boost, and adding a cooler, and changing the cam should get you to 600hp.

dont want to cut into the hatch, not even with the kit that fis into the sunpad foam. Flame arrestors r about 1/2" below. Also, want to rebuild motors completely to keep for next 2-3 yrs. Only so much $$$$ to spend

I rebuilt my 525 Hawk Blower motors-- used all the same components as the stock
engines had, they had 405 hrs. on them. ran 4900 at 72 mph.Everything is new but the block 30 over 468 cu----- now 5300 at 76 mph. with 25 inch props.
Put a set of 27's on an went back to 5000 rpm's at 76 mph I can give you the name of my engine builder if you want + he gave me a 1 year guarantee. So far so good Have 43 hrs. an I'm thrilled ! They are in a 38 Top Gun--Carbon Fiber Boat.

You say Dart cast iron heads. I assume you already have a deal found for these?

You are on "a budget", too? The small blower is NOT your friend in this endeavor. You will need to keep boost pressure low, to combat heat, but you can spin it as fast as you need to in order to keep 4-5 psi. In other words, with good flowing heads and a matched cam, you can make your hp goal with no trouble with the little blower, but it would be easier AND CHEAPER to get there with a larger huffer and more boost.
