don't foget with the dart manifold you have to use staggered jetting in the carb

For a little more money, why not supercharge your existing engine. I put a ProCharger on my carburated 502 that had over 125 hours on it. I kept the boost down to a conservative 3.5 lbs, although I'm told that 5 lbs would still be ok. Since its intercooled, I did not worry about making any internal engine mods. Now the boat has over 200 hours, and has perfomed flawlessly (both engines). The boat is a 93 32' Fountain, and last summer I raced several new step bottom boats with either 502 EFIs or 500 HPs and beat them.

Just a thought.

PS. you forgot to add new props to your total $$ amt.

Got The Fever, a good thought it is. I have been giving it some thought and might just do that instead of the other up-grades. What kind did you buy,and what was the cost ? Also I did not forget about the prop,I have been looking. What pitch did you have and what did you have to jump up to ?

Yes definatly the blower,,, this way when I get you to over rev it to beat me it will REALLY come apart !!!!

Procharger means we are back to putting inconel valves in it by the way.

Mark,

Come do mine when your done !!! a 27' should be no problem for you after doing yours !!!!

Like I said,,, need help,,, don't be shy,, glad to help.

Where's Patti been hiding?

The good thing with the blower is I wont be forced to over rev to beat you . I just will beat you.

obnoxus,
It's called a rev limiter. The cheapest piece of mind I ever purchased. In my case, the Mallory Soft Touch. You can change out the RPM where the limiter cuts in simply by swapping out a chip.

I purchased a Stage I, since I was not going to go crazy with the boost. I also saved a little money by Not going with the polished model. If I remember correctly, the Procharger itself was in the $3,800 range(each), but this was 3 years ago. I also had to purchase a different carb (Holley 750). The prop change was not an apples to apples type change. I went from a Spenelli 14"x27" to a Bravo 15"x28" (I forget the exact diameters, but am sure of the pitch). I was also going up in elevation by about 3,000 feet (one of the reasons for adding the ProCharger). I did all of the work myself. It is easy enough for any mechanically minded person. The tuning, however, is another story. Just be patient, and don't go too lean.

Let us know what you decide.

Fever,

You don't have to try to convince me, I have a rev limiter on my boat !!!! It's that cheap guy with sunshine as his avitar we have to work on.

To slightly edit a line from Days of Thunder,,,,,, When the little needle on the tach goes into the red and reads 5,800 RPM,,,,,, That's bad !!!!!!! ( at least for a stock 502 !! )

A what limiter ? Obnoxus convince me ? Have not blown a engine yet from over revving. As you seen on my last outing with you, push it to the limit, and then got you to fix it Lifes short,why not get through this one as fast as possible ?

Paul,,,,,, anything that gets you to spend more money makes me a happy man !!!!!
