And yet, some of these guys, have absolutely, some bad azz running hardware. From guys like Billy Boats and his 140 plus mph Fountain, Kvogt with his 100 plus mph old school arneson flatdeck that is a work of art in itself, the Parvey boys, and so many more I can't even begin list it. Some of these guys, have been there and done that several times over, and tested and debunked many theories, and yet, these guys, are constantly discredited by other guys, because they technically are not "professionals".

Being new at this, I wouldn't soley focus on who does what for a living, because those of us who have been around a bit, know that, just because one builds engines for a living, doesn't make his advice, gospel. There have been decades of failures, incorrect combos, lies, cheat, and many other things by certain "professionals'. Nor would I rely solely on the advice given here, as gospel. Some of this stuff, you have to learn from experience, and you may not get it right the first time. Just as many of these "weekend warriors", have had to learn the hard way.

Something to remember, everyone started somewhere, and history shows, some of those most successful offshore racing teams, dating back many many years ago, were average guys, who simply had a passion for this sport. It wasn't based on who had a Tax ID number for conducting business. I wouldnt be so quick to discredit those who do this stuff on the side. There's some pretty bad azz guys around...who only do this stuff on the weekends. Often times, the first boats to the card stop, were put together by these "weekend warriors".
JOE, I agree with you, there are plenty of people with great ideas, or just different ideas, it seems no one can just disagree, a pizzing match has to break out over who's friends with whom. Most of us could could give two chits about whatever Midwest drama is happening as we don't know the people personally.

Agreed.


I removed 26 childish back and forth posts out of 40 posts that had been posted at the time. No value to the thread and just a rehash of the same bickering.

Its terrible that somebody posts looking for advice and then has to sift through all the BS to get to any technical opinions.

STOP or be prepared to be stopped by the Mods

The savings is offset by finding parts online to buy, bar tabs when meeting the people you met online, taking the boat places you found online etc..... its a never ending downward spiral.....

I dont want to lose alot of low end so i was looking to keep cam near the 225-235ish duration with 112-114 lobe sepration - also looking at split lift/duration to help on the exhaust side of this - i have straight thru hull with no baffles
keep in mind that the dual plane intake will help slow down low rpm reversion if you go with a little bigger cam.maybe sb can give some information on this.

Would a spacer make a similar difference on a hollyFI with tall single plane? Or would it just be one of those things to have on hand to play with when it goes on the dyno to be tuned?

I can if the OP wants to PM me. I've been poked pretty hard (behind the scenes) by a few members here last few days and I do not wish to make my reply on the dual plane / single plane reversion properties in public.

Ignition timing, as well as combustion chamber design/exhaust port design, plays a role in exhaust flow reversion as well. Its not just camshaft parameters.
