Pandering to Judge Phil on this one... (Page 2 of 3)

I do believe that would make it slower than the flathead...

If the flathead survives two races, I say put a blower on it. Just make sure it's one you can easily re-use on your new powerplant after you explodinate the flathead.

I have been researching this...so far with little luck.  Other than the obvious problem of supercharging a carb'ed car, most folks say it can only take about 7 psi even in the shorter stroke 218 that I believe we have.  Does not mean I do not want to try it...

A PCwhat valve? Do you mean a road draft tube?

I think NSF had a 331 in their early 50's Mopar coupe.

We have the original radiator that we are pressure testing so if it does not leak we attempt using it. 

I know it will be slow but we are hoping to optimize the torque so that we can actually achieve a top speed that does not involve stopping for coffee by playing with rear gearing.

If you are not joking about the fuel effeciency, that means 142 laps per (usable fuel) tank or almost 6 hour stints!  Wahoo, we must invest in depends and nodoze!

Plan is end up with a 3.55 final drive and I forget which 16" tire but the end result is that the HP peak on the engine is 3600 rpm's so 70 mph in 3rd = 3650 rpms with this combo.  Unless we do a significant flow improvement, there is no real reason to exceed 3700 rpms as it is just noise.  I serious doubt we would ever be able to exceed 70 mph on either of our home tracks but if we ever get there, the same axle we will be using comes in a 3.27.

FYI, 1948's came with 15" wheels but still stupid tall tires.  We are no doubt going to be having to run spacers and likely massage a fender or two as "race" tires are all about 8" wide and those fenders were never meant for that.

FWIW, the Rambler was severely gear limited with it's original drivetrain and low profile Direzzas.  In AZ, it was redlined about 100 yards into the long straight at 65 or so MPH (lots of needle bounce).  For all the troubles they are having with the conversion, there's no way that engine even rebuilt would have lasted being passed through all the ham-fisted hands this year.  You know somebody would get caught up in the red-mist eventually.  Suspension condition was probably worse.  The short term pain of the modern engine/suspension teething problems will absolutely pay off in the long run.  I suspect that's true to hooning any pre 60 car.

#r^y>2: Dat 2.8

I can right nonsense as well.

Interesting...I recall looking up the original tire for my '49 Plymouth and they were 16"

World's Worst Inline?

One think to remember. If you're pandering to Judge Phil try to make sure he'll be working the race you bring the car to, something we're learning the hard way. I just hope Judge Steve has as fine an appreciation of the Chrysler LH platform vehicles and how terrible they are as Judge Phil does.
