I wont half-ass the important stuff and i dont like doing things twice.
And that's all that any of us were trying to help you with from the Get-Go!
No sales pitch.... no ill intent. Only your best interest in mind, as we would for any member!
******************************************
Let's retrace the steps here, and perhaps you will see how this evolved and perhaps how you came across to us.
Post #1 you lay out your concerns.
Post #2 Chris makes a good suggestion to you. None of us are able to see where Chris attempted to make a sales pitch.
Port #3 you asked why, and then went on to explain yourself as to the camshaft that would need to be swapped out. (looks to me that you already knew a portion of the answer)
Post #4, Chris in a friendly and polite way says;
"Sorry I did not give you the opinion you wanted to hear. I'm sure if you ask enough people you will get it."
Post #5 you become a bit smart a$$ed with your response. Very uncalled for!
Post #8 Chris quotes Despy and agrees.
Post #10 you say;
"But to flat out tell anyone that you must use a marine engine/long block that is just outright fraudulous."
Again... no one said any such thing like that to you. These are "Suggestions", not marching instructions.
I won't even copy your text in post #15.... It speaks for itself!
Then you go on to make these comments;
"Of course you want them to buy a marine engine....you aren't exactly neutral biased.....you are in it for the profit which is what any business would want....but to do it by flat out lying to people.......they call that fraud and greed."
"i just don't have patience with people that are obviously trying to screw people over."
(I would love to hear that one explained)
Then you post a comment that brings some reality back in;
"Thanks for pointing out that i was getting off on a tangent."
You were somehow able to say that to Bill (bondo) but not Chris or myself.... particularly Chris who was first to offer you a suggestion, and who was first to be slapped in the face (metaphorically speaking)! I personally think that Chris is being overly generous by even continuing in this thread.
"Appreciate you taking the time for all the heads up!"
This is the first polite comment that you made.
So I have a question for you.
Did you think that we'd react positively to your attitude shown in your responses, and did you think that your Navy experience somehow qualifies you to puff your chest up and show blatant disrespect to the forum members here?
In retrospect, I hope that you are able to see how this looked to us!
******************************************************
Let's get passed this now and move on!
Have you bothered to see if this Turbo ready 4.3L offers the correct C/R if naturally aspirated?
"I am quite familar with the OP switch setup for the FI engines."
FYI: the oil pressure switch is NOT an FI only requirement. The N/O oil pressure switch is a requirement regardless of the fuel delivery system (carburetor or FI). The purpose for the N/O switch is to shut down fuel pump and pressure in the absence of engine RPM (i.e., NO oil pressure). This is a USCG requirement. What you do for a momentary start by-pass is up to you. But this must be "momentary".
As for the head gaskets, this has to do with the fire rings and dissimilar metals being cooled by river/lake/ocean water that is not PH correct. These are known to eventually fail if not correct for an "open" system.
These are a few of the things that I'd be concerned with.
Again.... best of luck.
