Where to start?

-----I recently had two 383 boat motors built for one of my Donzis. 416hp and 466 torque. I named them the twins . Remember, these are boat motors meant to run at about 5000RPM and provide as much torque as possible in a broad range. I didnt care about the horsepower that much. Just 9to1 compression with mid 90s GM aluminum heads, cheap GM alum manifolds, 750cfm Holleys, and fairly mild roller cams. You dont need a tremendous amount of high-tech stuff, just the right stuff! A well built 383 will give you the most bang for your buck!!! ......Bill S

Bill any rough idea how much a nicely built 383 would cost to have built? I am not looking to make this car a street terror, I just want it to have some balls.

------Dave,,,Honestly, no! It can vary so much. These boat motors had quite a bit of extra work done in longevity areas as I want them to live for many seasons. Boat motors run at (sometimes) high RPMs for long periods and need very good balancing just for starters. A good 383 doesnt have a lot of crazy stuff internally, however so they can be built and built well for much less than, say, a small block 427. There are guys on the board that can give you a better ballpark area than me.........Bill S

BTW, I used to have a 1986 red and honey Minx but, got rid of it since I drove it like a maniac and was going to hurt someone if I kept it. I love the old classic Donzi's, Magnums and Cigarettes, they have so much more personality than today's modern boats.

-----Dave,,,In that case you would love my 24 DONZI Spitfire. 24 feet and 832 horsies!!! Rarest of the rare as we figure there were only about 15 made. Should do about 75/80 when dialed in . The muscle car of boats .......Bill S

------Dave,,,I would still put together a stout 383 and store your original. What happens when you build up the numbers match motor and then puke it??? As well, after your time is up with the Vette you can reinstall your original and go for the bucks with a fresh detail, all the while still having the 383 sitting around for another project or for sale. I dont know,,,It seems like a win-win to me. .......Bill S

Dave,

First off, let me say best of luck with your tranformation and that I would love to see photos of your car before and after. I have always loved the 68-72 last of the Chrome bumper Vettes and have had a few that were lots of fun over the years and am looking fowward to another at some point. Preferably a big block 4 speed a/c car(getting too old not to have a/c).

Additionally, since we are on the topic of boats, I realize mine does not have the character of the older boats, but she sure is lots of fun! Nothing like grabbing 3 friends and gear and hitting the water at a cool 100mph with a blown 572 Big Block Chevy! I'm guessing you have figured out that I am partial to Big Blocks by now. Not that I have anything at all against small blocks as I have a bunch of them too, but there is just something about a Big Block that always gets me going. Here's some pics of my dingy for your viewing pleasure.







Have a great day everyone!
