Toploader trans wr or cr?

275/60-15=28 in diameter

So if you are running 28 in tall tire, you need to multiply Mike's results by 28/26=1.077

Something else to think about is being able to drive your car into a trailer. For my old car 427 FE, cam with lots of over lap, 3.31, CR, aluminum flywheel, and a 28 in tire, it is very difficult to load into the trailer, with out smoking the clutch. So I drive fairly fast into the trailer. I really should use a winch.

My other car, 302 healthy cam, alum flywheel, CR TKO 600, 3.54, 26.6 in tire is easy to drive into the trailer.

Tom,
if you don't mind me asking, what have you determined is the advantage of an ultra light weight aluminum flywheel vs. say a 32lb stainless on a warmed up FE?

There have been many debates on the aluminum vs steel flywheels on Club Cobra. But to quickly answer your question and not hijack this thread, the advantage is the engine accelerates faster. This obviously helps in accelerating the car... but it also helps in shifting gears. The lighter flywheel helps the engine speed match quicker to the transmission speed. This is most apparent when heal and towing.

I am also running an aluminum flywheel for all the reasons Tom mentions above. Although, Tom's other reason may be that his real goal is to build everything out of aluminum! Just holiday kidding.....

just to pile in here:

i will be using a WR toploader with a 2.88 diff when my FE428 arrives. i wont have the fastest accelerating car, but at least it wont be on very high revs at 70mph. i want 4 speeds that will be useful, and i'll sacrifice a little acceleration on the way.

I know several UK FE guys who are swapping to taller diffs having used 3.38 with tremecs.

I hope you don't mind me butting in, Duane, but here is my opinion on the aluminum/steel flywheel issue:

I think for the street an aluminum flywheel is kind of excessive (pretty much just like the car itself!) and I highly doubt that most of us coud tell the difference in how quickly the car accelerates with an aluminum flywheel as compared to a steel one....a light flywheel (some of the steel ones are pretty light too) just makes the car a little harder to get off the line as it doesn't have that "flywheel effect". (hmmmm)

However, the reason why I used one and continue to use one is pretty lame....I just love how quickly the engine revs when you rev it when stopped and how quickly the engine stops when you shut it off. Real racy sounding.

A friend has a stock steel flywheel in his ERA and that things sounds like an old Lincoln when he revs it. Sure drives nice though.
