    Default new project for alpha drive

    Ok, here's the scoop. I have a 16 ft carlson cvx outboard that I would like to convert to Z drive since I have a boat and a hot little SBC laying around. What I don't have is a drive. I know where I can get a complete alpha leg, gimble mount plate, pump and cylinders. I'll be needing steering and gosh knows what else. Question is,,,,,,should everything thing I get be for the alpha of that model (pre, gen1, gen 2) like steering ram and bellhousing? I know the uppers and lowers have to be the same make.

    Default I have an alpha now

    I got my hands on a complete V8 engine and alpha drive from a boat that was scrap. I may end up mounting the drive 1 inch higher than the normal place.

    I had a 1977 CVX 18 that I installed an Alpha SS ( 2 1/2 inches shorter than stock ) and then raised the drive 2 inches. The prop shaft was 3 inches below the pad bottom. The boat liked that setup. Top speed was 94.

    Thanks for the info. Since I don't have a shorter lower,I'll have to measure to see how high the engine will be in the boat. Here's a picture of my project thus far. Since the boat was free and in good shape (except for the wood part) I don't mind cutting it up. I cut out the motor well and moved it forward 22 inches for engine room and to "tighten up " the passenger compartment. My design so far is to have center steering with 2 rear passengers. (that way I won't hear the screaming as loud) I've built custom cars in the past and I sometimes go too far in the design, so I was playing with the idea of an off shore style with air intakes and a rear wing simmular to a Lambo Countach. The windshield will be wrap around instead of the "mock up" in the picture.

    Default still at it

    I split the boat and started the floor work. I ran 2 stringers forward for engine support since this was an outboard boat. The keel is a 2x8 that was cut to be as high as the 2 motor stringers and dropped down to a 2x4 in the motor well. Next week the boat goes in the garage to start on the hole the the transom and lowering in the engine for motor mount fabricating. Click image for larger version.

    The engine is a 400 HP 355 that I had in the shop. I chopped the upper deck at the outboard motor well and moved it up 22 inches to make room for the engine. I am now in the process of building a motor cover with integrated carb scoop. The exhaust is camaro headers turned upside down and reversed.

ID:	441217I'm still at it! I've changed a few things around. (worse than a woman) The head rest flairs are gone. After a while they just didn't "work" for me. I cut up the swap meet headers and re purposed them into zoomies. Chrome tips from Ebay and self built baffles. I hope Santa brings a shotgun carb scoop,,,,,Santa,,,,are ya listening?

    Tinkerer. Did you run power steering? I have a clearance issue and may have to go without.

    I like the style of the boat and should be allot of fun , I would be concerned with non jacketed exhaust in an enclosed bilge.

    Keep the progress pictures coming !!

    I have heat shells to install to protect the paint. The scoops on the side are there to let air in to vent the bilge and exit out thru the exhaust and engine openings.
