Oh..... filing up at a gas station 93 - sometimes available.
93 on the water - not very readily available on many lakes rivers and marinas.
The highest you set should an older (non LSX) small block is for 91.
10-1 engines basically.
You get many more bad batches from marinas than from stations.

Hard to do 550 with anything under a 434 and have it idle and be drive friendly.
I would not focus on HP if I were you but Id focus on torque.
Like the prior poster asks- whats it got in it. You may not be able to "get there" from here without a lot of new stuff.

With the velvet drives the shift is smooth, I don't know if its hard on them but I think I could run the idle up higher if I had to.

Find out exactly what you've got, first. Then, let us know what your budget is, and we can recommend some stuff.
Budget is the main consideration, here.
I would guess that UD's build with a little less cam should work pretty well for you. Forget about chasing peak HP, lots of torque is what you are looking for.

You wouldnt be risking gears, but would just be harder on clutches.

U.d. Great info.was that boat in the vid turning 9k? If you wouldn't mind sending specks on the motor that would be great!!!
I have help lined up for machine work hull blueprinting and paint.
As far as budget I would think if I can use the cranks,rods,heads,blocks and roller rockers that the rest can be bought reasonable.

My 383 made 595 HP running 8.8:1 6 psi from a 2.3 liter Whipple, ideals almost like a factory engine relatively easy to dock and is pretty good on fuel useage if kept cruising under 3,000 RPM's. move my Donzi 18 to 90 and is enough to freighten the average thrill seeker. I'd think that kinda HP N/A is capible but as mentioned will lean towards a unfriendly idle and poor docking. Goodluck with your build.

Why fool around reinventing the wheel? Raylar has them.

Don't really need 550 ponies or don't have the $$$ for them?
Contact Diego9040 or see his thread titled - Looking for 400HP
on 383's. These engines will be for sale soon.
You're going to be spending a lot of money no matter which
way you go so make it as easy on yourself as possible.

ok, an 83 Nova is not the best boat for this fairly exotic drivetrain. in fact it is about the worst. it isn't a very fast hull, and it isn't a very valuable one. that hull, less power, needing cosmetics, is worth about a thousand bucks tops. that boat when done and perfect will be worth less than you have in the engines. you are talking spending upwards of 10k on engines. find a hull that deserves them, pull the arnies out of the Nova and put them in a Fountain or a 28 Donzi. something like that. build the engines and run them in that hull for a while, but don't get attached to it. and don't put time and money in that hull that isn't removable.
