I'm running those Edelbrock heads on my motors. In stock form they flow terrible on the exhaust side, and that is not good on a blower motor. I had to spend $$$$$ to get them ported correctly. If you have the cash aluminum heads will make more power and also make the motors live longer. They pull out some heat from the cylinder if you are running higher boost numbers such as me.

i dont know anything about em. if they would have fit carb'd engines, i would have called about them

Hawkeye had a 29 w/385's and prochargers.

Had 32 pitch props.

As I recall it was a tick....just a tick faster
than my 29 w/HP500s

Tick

Tick Tock

A tick is exactly 1.3 MPH I think?

Definitely go through the engine. Good head gaskets is a must. Once you get everything installed, write down every modiication that you made and send them along with both computers for each engine to Dustin Whipple and he will get the computers right. I had the same setup on my 25 Outlaw except I had the 502 efi.

Make sure you have sufficent fuel to both engines, by upgrading the fuel system.

Have fun it took me about two month's to get our's dialed in correctly. You probably will be in the 30-32 prop pitch.

Don't bother Dustin with the computers. Besides he is doing R&D only now. Two guys can set up the stock Merc Mefi comps to do what you need. Tyler Crockett in Michigan and Mark at Precision in New Orleans. Best way is to dial them in when they are installed in the boat. I'll be talking to you this weekend.

So that is 83ish?

is Whipple still in business?

Whipple is still in business. As a matter of fact they are building a better product.

just havent heard much lately about them, Is the support there?
