The 600 Edelbrock will work just fine in this application it is not "way to
Much" and it would appear that the price was rite! Using the standard type
calculations you get
390 CFM 4500 RPM so theoretically your recommendation of a 450 would be
too large.
In fact the 600 Edle. is a semi spread bore in that there is a difference
between the Primaries and Secondary. When run with an educated foot this
Carb will meter fuel quite well. Yes it is on the large side but the price
negates that. The Jetting kit for this Carb should be purchased and an O2
Sensor should be added to the price of the engine just to make tuning
easier; but the Carb will work just fine, just take a little longer to get
perfect. I run this Carb all the time on engines in the 289-302 range and
have even run one on an engine that had a 122CID.

SNIP
This engine runs sooo well on the bottom end (like a diesel) because it was
designed to is correct; but to then say that it will not perform well at
higher RPM's is incorrect. Consider the way that the engine is set up.
Generally the cheapest manifolding that Ford could get away with; however at
low RPM's it will work. Cam timing events that are again specifically
designed for low RPM work. Most of the time we are looking at a 1 BBL or
small 2BBL. Here again the bias is low speed operation.
The compression ratio's are also generally conservative.
Looking at the potential of this engine... IT's a FORD and you cant start
out better then that. The 300 has a pretty good head on it (Cross flow
design), and you can clean it up in the ports and add some larger valves to
get the flow potential. The bottom end needs good quality fasteners and
everything Mag'd but other then the standard machining operations it will
live at a higher power output just fine. Add the above manifolding and the
Carb, kick the compression ratio to around 9.0:1, or so using a forged type
piston, and all that you need is a Camshaft. Duration figures would be
about 215 to 235 degrees or so. Yes that is a big spread but I don't know
exactly how the project will be completed. Like I think that the FDR it to
high and should drop to about 3.7-3.9:1. So with high gears (low #) run a
lower duration on the cam.

I really appreciate everyones advise and tips, I getting pretty charged up
about getting started on this project.

Not to totally reveal my newbie-ness on automotive tinkering, but to verify
effects of "overcarburation", couldn't the secondaries (since they are
manual) be disconnected as a comparison (ie, making it ineffect a 300CFM
carb) on overall running and performance or is this going to throw things
so off I'm just going to make matters worse?

While we're here, doesn't methanol need more static compression than
gasoline to produce equal power? It would seem that it would be less
prone to detonation(very important in Truck-Pulling), so you could tune
a given combination "hotter" But without more compression, does it
really make more power than a gas engine with it's proper octane
requirements met?

Would this system happen to use a vacuam sourced potentiometer to sense
load? I've theorized that if you could use the vacuam signal and break
it down into the smallest increments readable(like breaking down an
electronic wave-form and reading it in micro-volts) and tie it to a
microprocessor to incrementally control spark(and on EFI, the fuel)you
could be stoichometric under any load condition. On an older style
engine it would greatly simplify the installation of EFI and ESM,
because the network of sensors new engines use would then be redundant.
On a racing engine, there would be no over-rich or lean-out conditions
to deal with(or compromise for)when running under changing weather
conditions.

He refuses to get a V-8 - claims they are nothing but gas hogs and
extra weight.

The 6 doesn't get that much better mileage and if you are working it, it
is just as bad as a V-8!

From: "wild.bunch"
Subject: FTE Perf - Methanol Fuel

The major power gain achieved by running methanol fuel is due to the
increased BTU content of the intake mixture. Gasoline has many more BTUs per
pound, but is mixed with air at a relatively lean mixture. Whil methanol has
less BTUs per pound, many more pounds are contained in a given pound of air
becase methanol is run very rich. To put it another way, a pound of air
contains more BTUs when mixed at the correct proportions with methanol than
gasoline.
There is also a potential power gain due to the ability to run a higher
compression with methanol due to its very high anti-knock rating compared to
gasoline, but this is in addition to the inherent BTU issue described above.
Methanol runs cooler, too

yes, methanol can handle much higher CR. but that is what the initial
thread was about, how to run higher CR, and the meth gives that ability.
and it most likely would make more power than gas at same CR because of the
cooling effect of the fuel, and it is run at 6:1 instead of 15:1 mixture,
even though it has less btu per gallon energy.

running alcohol takes more than just dumping it into the tank. the whole
fuel sytem must be set up for it and it takes a system capable of flowing
more volume of fuel to run the same engine on alcohol than on petrol (gas).
