A little help if you have a minute..

Ok like I mentioned in this guys other thread I purchased this boat off him for a great deal in my favor.
We had some above average temps here this past weekend so my friend and I took this boat out on the lake to see what this thing will actually do. It's embarrassing to even post these numbers but I thought since the previous owner left you all hanging the least I could do is give you real non BS numbers.
First off the conditions were as follows::: Smooth water, no wind , temp low 50's, 1/2 tank of fuel, 2 adults. Max speed 49 mph @ 4800 rpm spinning a Mirage Plus 23P 14 5/8 prop. :brickwall: No way in hell this boat did mid 60's like he posted after the engine was installed.
Now on a positive note there's 31% prop slip and if reduced to 12% in a perfect world it puts it in the low 60's. Now fella's how in the hell do I get rid of 31% prop slip? The boat has one coat of *****ty bottom paint on it so there's some additional drag but doesn't account for creating 31% slip. I talked to Kip at Checkmate and he said this boat should be running hi 50's taking the SB into consideration. The X dim. wasn't changed when it went from a BB to SB. Any suggestions are welcome.
 
You, have a torque problem. (:poke:). Displacement will cure this malady. Bottom paint might cost you a mph, maybe a little more if really rough. Leave friend, cooler, extra batteries, tools, fishing gear, anchor, mooring bumpers, boat cover, cockpit cover, and transom tie downs at dock side. Get her nose into the air and as much of the hull out of the water as possible. Another little tidbit from the 'Book Of Jim' : "Loose is fast". WOT RPM is telling a story.
 
Jim, I just got my hands on a low hour 502 mag with low hours just waiting for me to drop it in but I'm interested in following this this through for a reasonable amount of time to actually see how fast I can get this SB up to in this boat. Now that being said since almost 200 lbs was removed from the stern by going to the SB would the excessive prop slip be contributed to the stern/prop sitting higher in the water compared to what it was with the big block? I was reading up on drive spacers to get more bow lift in addition to reducing prop slip as they claim they do. Thoughts?
 
I'd look into cam, roller rockers, intake and a few other parts and turn that 502 into a hp500 clone. You could easily pull and sell the 383 for decent money to invest back into the boat.
I think spending money to make the 383 run higher numbers when you are going to swap it out anyway is wasteful.
 
Hi Shortbus. In the realm of Rat, yesterday, around casa del Jim, the roads dried out for a time. I strategically blocked Mrs. Jim's automobile in the driveway and misplaced the keys to the blocking vehicle. I did not want a recurrence of last year when Mrs Jim showed up out of thin air at the starting line. She has been scrutinizing me intensely ever since 'The Flames' old Chevy has come to stay. The old girl has been washed, waxed, vacuumed, checked, changed, and replenished. I happened to innocently drop by the local country store while warming up the old girl. I just happened to find the little silver Subahoo parked right out front, it's little blue wheels glistening in the overcast. I had just completed an approximately 75 mile long run. The old girl was nice and warm. Me too. It still surprises me how physical it can become when trying to move a vehicle from point a to point b in the shortest amount of time. She likes to dance and actually responds fairly well to a heavy hand and foot. In addition to being built for magnificent bursts of neck snapping acceleration, she has big front and rear weight redistributing bars and big brakes and will more than hold her own out on the open road. I must admit right here that the little silver all wheel drive machine, with it's rear wing and carbon fiber hood is a rather nice looking ve-hicle. It's turbocharged and apparently fairly well massaged by Racer W. They state that the engine size has been increased as well as the turbocharger, boost pressure, etc. "Where's your Wife" asks Racer W? I quickly shoot a nervous glance in all directions. "You'll be running against the big dog today" I say. "More like old dog" says Racer W with a snicker. "Ugly too" adds one of his cohorts. "You ready to hand me some money" asks Racer W? "Sure, if you can get out in front of this bad girl" I state. Racer W starts the Subawhat and revs it up so that the turbo can make it's sneezing sound. "Gesundheit" I say loudly and smile. I slip into the old girl and give the key a twist to the on position, listening for solenoid clicks and the whirring of the fuel pumps. A mere momentary bump of the key to the start position illicits the big popcorn popper sound from big exhaust pipes. I give her a little air. 427 cubic inches of tri powered fury firmly announces it's willingness to snap necks, vaporize big wide drag radial tires, and remove the upper layer of asphalt from the road. I see the store's customers and owner come eagerly piling out the front door as I pull from the parking space. In a few minutes, The old girl will pass by the entrance at close to 130 mph. Well in excess of 500 horsepower will be leaping and lunging down the road. The old girl will be lifted in the front end but leaning over towards the passenger side as she flies by. It should be pretty cool for them to see. I back up and reach over and roll down the passenger side window. "You Folks keep a close eye on who wins" I tell the growing crowd. "You bet" says the store owner as he steps forward like a dignitary and motions for every one to step back!
 
I and Racer W (the W is for wannabe) traveled to the starting area at the other end of the straight stretch of country road that passes by the old country store. Racer W picked the oncoming lane for his choice (probably because he seems to spend a lot of his time driving on that side). I offered up a little contraption that I came across at a swap meet years ago. It is a starting tree of sorts. It has two yellow lights and a green light. Once the button on it is pushed, The first yellow light at the top of the 'tree' lights, followed by the next yellow light, followed by the green light. The person selected to line up the cars that are challenging, lines up the vehicles, then pushes the button. When the green light illuminates, truth very quickly follows. I might mention, in passing, that having had the 'tree' in my possession for sometime, I have first hand knowledge of how fast it triggers each light (heh heh). Ricer W, I mean Racer W, may not have thought about this when I offered up its use. This tree stands about 5 feet tall and can be picked up rather quickly and carried off should the need to vacate arise. I set some pressure on the front brakes and brought the engine up to 2800 rpm and whittled some rubber down onto the road for a few feet. I backed up over the fresh laid rubber. I put the trans brake on and brought her up to about 3500 and switched off the brake, causing the car to jump forward. It will loft the left front wheel if there is enough traction present. You might well imagine the sights and smells of an old gold and white Impala, stock looking steel wheels with little chrome wheel covers (poverty caps, we called them back in the day), backing up while the driver opens the door to back right over the fresh strip of rubber. The door closes. The driver nods at the starter person. The old girl sits ever so slightly higher in the rear. Header cutouts can be seen just behind the front tires. The rear axle is somewhat narrowed to accommodate wider tires. I glance over at Racer W and he does the rev limiter, turbo sneeze, purge the nos system with puffs of vapor thing. He glances over at me. I rev up the old girl. She rears over toward the passenger side of the car each time the throttle opens. I look back at the starter person and nod again. The first yellow light illuminates. I select low one and the trans brake and bring her up to 2000 rpm while silently counting in my head. As the second yellow light comes on, I bring her up to 3500 and tuck my chin. Anticipating the green, I release the trans brake and six butterflies in three carburetors come almost vertical. It feels like getting hit by a three hundred pound lineman in the back. It takes about three seconds to get her straightened up and reach top speed in low one. I strike a blow to the shifter with the palm of my right hand to select low two. I am quite surprised to see the little silver car abreast of me. That thing has a launch like it came out of a sling shot. Second gear lasts about another three seconds. I smack the shifter again. The finish line is approaching in a hurry, about four seconds after hitting high gear. So is somebody that is standing in the middle of the road at the finish line. I am a little more than perplexed but recognize the store's owner sporting a strange look on his face as we fly past. I shoot a glance in the side mirror, there's nothing there! I do make out what might be the rear end of the little silver machine in my peripheral vision. I look forward. The speedo is buried past 120. The old boat anchor big block is pulling like a freight train when I blow past the entrance of the store. As soon as I'm off the throttle, that silver car is right next to me. I'm a little concerned until I look at Racer W's face as we slow down. Once I get the old girl back out of the air and onto the roadway again, I turn around and head back to the store. I'm gonna have to have a talk with that guy, I think out loud about the stores owner. We pull in and climb out of our prospective vehicles. I look around nervously, expecting Mrs Jim to jump forward from thin air and grab up the prize money. The store owner is pounding me on the back and describing what it looked like when we flew past. I step over to Racer W. "What did I get you by" I ask him? "Not quite a car length" says Racer W. "You got a good jump at the start" he adds. Someone from the crowd is leading the store owner to a chair. His hands are shaking and he is real pale in the face. He looks up at me and smiles a faint sort of smile. "I just cant believe that you stand out there like that to see who wins" he says breathlessly. "It takes a little getting used to" I tell him matter of factly. "I tell you what though" I add, "You looked like a pro, nerves of steel, if I may say so"
