Agreed.. I would probably rotate the wheel 180 reattach the "tool", and look for it to agree with the prior location..
Your post reminded me of an occasion years ago.
I'd taken a friend to pick up his car at a shop and look at some things while it was on a lift.. In the next bay a car was...
Is this a new class?
Or do you know which configuration last seasons winner uses?
What's the rule on fuel?
Are these high pin pistons & long rods you mention readily available? affordable?
As weight is not a problem, and rotating weight may even be desirable.
I'm still going with bigger is...
The second BB option has nearly the same bore & stroke as the SB..
But, I would guess it has bigger valves and more importantly, a longer con rod?
If So, I'd be leaning that way.
But, we ARE missing a ton of info.
As to the why of that statement.
I'm guessing the cam maker would rather you wear things out from excess pressure than destroy them more catastrophically from too little..
This was 25+ years ago and I don't recall the details of the conversation. He correctly pointed out that his people...
Some more questions & comments:
Did you see a substantial performance gain with this cam switch?
Is max performance/efficiency even an issue?
I had a similar problem years ago. I was seeking maximum reliability & durability in that same engine
and so was wanting to use a mechanical
(not...
Well, it's sounds to me like you've got a cam that sounds mild by the numbers, but is actually a bit too "radical" for the sort of longevity you want.
And It's just beating up the valves/seats & lifters.
Still..
If I were the lifter manufacturer I would probably work on some positive oiling...
"The loadings you are using do not coincide with the wear on nose of cam lobe."
A bit vague, no?
I will guess he's saying the cam wear exceeds what he'd expect at those spring loads & hours of operation?
May I ask what the part# on the heads is?
Did you switch to a roller cam to try and...
I'd keep driving.
Your oil has 3,500 miles on it, in that it traveled 3,500 miles.
It likely has quite a bit fewer rpm/hours on it than you would typically have after 3,000 miles.
AND, as you noted. far fewer cold starts, and just fewer starts.
far less cold operation, idling etc.
That oil...
The "secret" to the modern engine is, as you and others have said,
Modern machining, round bores correctly finished etc.
That said, for break in purposes, I would run conventional oil until the first oil change.
And, in case it hasn't been said enough already;
Do raise the compression.
I suspect it has nothing to do with lug nut type.
Maybe the more modern washer style is just accompanied
by more modern theory,
(that the Coriolis effect is too small to worry about)?
It's definitely more trouble than it's worth.
I've seen lots of valve springs where a stripe or dab of color
is used to ID. I don't know what the wind direction is about.
Torquey; In the OP you say "roughly half" Does this mean It's not precisely half as you'd expect if say, larger valves got a higher rate spring?
"a few feet wider than before"
I'm visualizing big heavy spacers.
Is there a weight limit? Tires full of water?
I wouldn't expect much from increasing track width alone.
Locating ? Load carrying
I think some of the lug pattern changes in modern
cars and light trucks are designed solely to give the oem an
advantage in wheel sales.
Should never have spoke of it.
Just bought fuel and for the first time in ages the spread was more than 10 cents. only 11 an 22 but still ...
I'm pretty sure there are vehicles that are more economical to operate on premium ( I hope so, I've put considerable effort into making it so.)
That...
My 2 cents,
Have you ever operated this unit for an extended time with no pipe smaller than say 20"-24" ? looking at the picture i can see where it may have trouble with smaller diameters.
I am on the high side of the air pressure debate.
Unfortunately the issues i see and every factor...
I see a couple of problems,
You appear to be confusing ported vac. with venturi vac.
ported vac. is the same as manifold vac except the throttle has to be opened past the port, so no vac advance at idle.
some 2100s have a venturi vac. port higher up the carb. that could give you the sort...
thundair,
I think everyone knew what you were talking about
I was just confused by some of your #s.
Is that diagram referring to a specific engine ?
I'm not sure I agree With claim of max pressure and max leverage coinciding. and not because i think that word should be used only...
