3.54 rearend?

[LanceM]

I put an 81 5 speed in my 240 with 3.36 gears, needless to say my low end just isn't what it used to be. I drove the ZX with 3.90 gears and they were too low for my driving/liking. I've got a 3.54 rear and have been thinking of putting it in, but is it worth the trouble? Will it give me the zip of the old 4 speed first gear or will I have to go to a 3.70 or 3.90 and put up with the high rpm cruise?

Never mind, I found a site with all of the ratios on it and made up a spread sheet, looks like 3.90 is the only way to get what I want... Think I should have kept that 4 speed...
