Re: Wiring harness schematic SBC

Anyone have a good Wiring harness schematic for a SBC with carburetor. . . . Have a brand new harness already here. I admit to being a dummy sometimes, and maybe haven't had enough coffee yet, but a SBC w/carb seems a little generic. I'd think that the flavor/type of ignition system your harness is...

Re: Trailer tilt or straight

Smuggler on here builds a very nice aluminum trailer with the torsion axle and roller face. He would be a great contact for you and is located about 45 minutes south west of Ocala. Agree but Smuggler does not build tilts! A tilt does come in handy at times of low doors or anything dry. I've just fo...

Re: need advise

Don't be stupid about a 200 hp build vs a 700 hp build regardless of what kwan has seen on yotube? If you can clear your transom with prop and torque roll, better off! I've cleared mine with a 88 jw x 4 on a pumped ls6. Most think high is a negative for torque roll but new blades cut real good. Gran...

Re: Anyone running Sensenich JX? If so what pitch & WOT RPM

Two 78 jx behind a pumped v6 on a 268 gear at 21.
Love them and totally american, No whop like the s blades and cut 80% better for torque roll vs S blades
Not grand at 6000 or over, prefer 52 or 5300 behind a 268 in mid to low 20's

Sorry, Gary just pissed me off with his extensive knowledge of your question? Ask any vendor of their process is normal!

Re: Lets talk about harmonics

Good post all! I think this applies to a tuned boat that most are lost on! Whether it be bad stringers on a glass boat that adsorbs vibration or one blade a hint off on a 100K rig? Harmonics are huge to a quality rig! Bad harmonics will break anything eventually! Plus it's tough to find, normally? R...

Re: NEW boat build- weighing my options

Maybe so, but no telling it's future. Motor choices are at a crossroads right now in the v gm format! VVT eco tech gen 5 is out in 5.3 and 6.2 and makes unreal torque at below 6k stock! Kind of real time compares to a ls3 or maybe better in stock format with the vvt. Hard to say on this as gen 3 do ...

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...

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...

I'm running 4 88's, but has nothing to do with this post of 2015 or the advanced knowledge of LS since 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...
