Thats a good???
I would like to know that also
Wich all depends on the tire size also
With what I've read 31 inch tall tire 70mph 327 gear is about 2400 but I've read that it about 80 horse to do it with all aero dinamics of a model a

What can't be done
I don't know the meaning of that phrase

Oh my goodness, I'm the same way, sometimes to my own hurt!

What I am saying is that you can not read too much, as in,
You can not get too much knowledge or study too much about something that you need to know or need to do.

In response to you saying "I read too much" I say

"You can't do it" read all you want!

The problem is
You can't believe everything you read but weed thru it and pick the subject apart look at the situation twist the head around a couple times and if i do this will it work or just go for it

Absolutely correct, You have to make your own decision and research it all.

I was told by a couple "in the know" Model A folks that my motor would not run because it has no flywheel.

In racing, the trick is to ask questions.
To go fast, you have to ask the right questions and people.

What is a safe rpm range, something in the realm of "normal" for this engine

pretty please ?

I have a 29 roadster I'm working on at the present time
Just got the body in primer last night now comes the block sanding

There are far too many variables to give you a solid answer.

That said, I would talk to Stipe, Burlington importer, Antique Engine AND whoever put the motor together.

For what is "safe" or "normal" trust your butt, ie, the seat of your pants. When you do not feel comfortable anymore, that's enough. However, these engines will do much more than most people think they can as the hillclimb/racer guys will confirm. Any highway speed is fine, even dead stock, and modified with counterbalanced crank, etc is even better. The limitation in most driving is vibration and what you feel comfortable with.
The real limiting feature of the Model A design is the oiling system. Conventional wisdom is that 4000 rpm is starting to exceed stock/splash lubrication capabilities. And you do not drive your modern car at 4k rpm for very long either. You usually drive it around 2000 plus or minus, which is fine for the A engine too. Babbitt is fine at any rpm so long as it gets oil (just like inserts). The Bonneville/dry lakes go-fast guys have proven that years ago.
So just drive it. The more you drive it the more comfortable you will be at any speed. Get a tachometer to follow your driving habits and time your shifts. Its actually kinda fun and will make you a better driver.

Those are more or less the numbers I achieved on Pendine Sands in the 29 CCPU in my avatar - B engine with an ali Winfield head, SU1R cam, single 97 and Mallory distributor (actually 69.87mph @ 2411rpm) with a 3.27 rear end on 21"s. It will go faster on tarmac, but not by much.

Really doubt it's making 80hp though.

There's a formula somewhere for calculating power from measured speed/gearing/frontal area. I'll go look it out if somebody will tell me the frontal area of a 29 CCPU

I seen that the other day but don't remember where I stumbled across it

Pardon me , but why wreck an antique engine beyond what it was never intended to be? You'll only shorten it's life. There are plenty of 4cyl, ohv, 100 hp engines available in the boneyards. Throw in a 4 or 5 spd and you'll have what you want. I saw one in so Jersey with a Volvo 4 cyl. I don't know how it ran, but it was a nice, clean installation.

The last thing i want to do is ruin the motor just want to upgrade it a little bit
Yes i might be hot rodding it a bit but for the most part i want to keep original also.
I could put anything in it but, i am choosing to stay with the motor the car came with
