Re: Powering oil tanker with airprops (is it possible)?

My answer is no................. I haven't read anything below the ops question but I do have insight into the question itself. Even in diesel format and wind tunnel props, Id say learn to drive or hire a harbor pilot or tugs. I sure hope this is a joke regarding tankers from other countries and sea...

It would help to know what the 6 blades are set on presently? The prop pitch alone could hold 100-200 hp in a guessing game?

Re: Ls1 hp question

Well if it is an 03 From a corvette they offer 2 options ls1 and LS6. Both are aluminum block, so if is an iron block it is not an LS1 or LS6. Main difference is heads and cam. Factory rating ls1 350hp LS6 400hp. You have no Power steering pump or A/C so maybe a tad over those numbers. IF the heads...

Re: Got a SS welding question...

Rick, Maybe too late but I'll give it from knowledge and post use. 100% argon is safe and corrosion friendly to a possible salt use boat or rigging. Assuming it's maybe polished welds and such? 75/25 also works but pits rust in a couple years. Tri-mix is freaking grand to weld and cleanup, but again...

What prop are you running dd on a 6.0 ls
I'm running 4 88's, but has nothing to do with this post of 2015 or the advanced knowledge of LS since 2015?

I do have a sbc and or bridge for sale if DD is really your thing from 2015?

Re: Building a new 500 caddy for a 14 ft Viking Need help with top end valve train

The correct answer is completely contingent on the intended use and the subsequent RPMs. The factory rocker system/design is adequate for Direct Drive RPMs provided everything is in good shape. Having an engine though, that's nearly half a century old with that little valve train wear is not likely...

It's as strong or weak as you want to build it!
From a wrecked caddy or truck to a brand new build from any manufacture is real. It's not will alum hold up! It's what you buy from who in alum that will hold up?

Re: Stringer replacement

A valid post! I've done both! Ripped and stripped them down to turn the hull into a hot plastic mess and ripped them up high enough to pressure wash the wood mush out! If it ran good prior, I'd say rip it high and deal with the stringer shells and a very good wood planner for the new internals. If i...

It could be worse with M&Ms labels on them?
Now this is a die hard build with fuel as it is and LS's approaching the norm on pump junk.
The good thing is it's being built with vast knowledge of what it's being used for!

To date, nobody is willing or financially able to test thrust on the same motor on the same boat per gear or belt or prop or rotation!

OX Clutched or Direct with or without fluid?
Total package or no bolts?
Weights usually apply to gear to gear or belt to belt, but if it's hp loss to gear drives or belt drives, that should trump weights any day of the week!
