he was running with the current

Sounds about right to me. The Dart heads are a big improvement over the GM heads. With those heads, ECM tune and pulley change it sounds right to me. Sounds like a nice package. Similar power to a Merc 700sci.

He is probably trying not to scare off a buyer by saying they are worked over is my guess.

Your engines could be made into 700's pretty easily and still be reliable. Just need better drives.

This will tell you all about how a 353 running 100 plus works... its my buddys boat.... not crazy power at all.... 107MPH and counting.....

Nope

I was going to do just that but the drives are the expensive part of that equation. Some people tell me that the XR drives can handle it but i'd have to really baby it. I don't beat my boat but if you run in some snotty stuff, sometimes the drives pop out and growl no mater how easy you go. You run the bay , you know what I mean. Got any ideas? Converting to 6's would really cost and i don't think i would ever recover that money in the resale or even a fraction of that cost. Someone once told me if you want to make your boat faster, go buy a faster boat.

Mine runs 97 with Whipples, XR's, no boxes and 5 blades. Im sure if I switched to 4 blades I would be at 100, but I prefer the better mid range the 5 blades give me. I if put shorties, boxes and 4 blades, who knows?? I would think 105 +.

By the way, the guy a few docks down from me has a kevlar 382 with warmed up 700's and NXT's and I think he runs 105 or so..

What engines are you running and what drives?

525's with Whipples and XR's.

So how do your drives hold up with the whipples? and what hp are you at? Im asking because i want to put whipples on my boat and make the 525's into 700's
But I'm afraid of everyone telling me that the drives won't hold up.
