Re: M20 wide box
 

Hmmmm.... I thought the M20 box had a 2.52 (sometimes a 2.54) first while the M21 had a 2.20 first?

Hay Birthday boy,I pulled my M22 B4 going to SCR XIII and put in a M20, and with my 4:10's I was able to eek out a 13.50 @ 103. It's still in there, allot more fun driving around town too, I just miss the noise my M22 made... [img]<<GRAEMLIN_URL>>/grin.gif[/img]

Re: M20 wide box
 

I have a M22W (wide ratio) in my car. This way I get the best of both worlds.....easy taking off and the noise of a M22. The only thing I don't like is the RPM drop from 3rd to 4th at the strip.

Re: M20 wide box
 

THAT is WHY you GO to A 4.56 ratio KURT! Trans End from Jersey made gears for a Muncie about 40 years ago giving you the low first gear and the M21 high grear ratios. Don't even know if they are in business anymore. Put .88's in it Kurt with a taller tire than you have a choice. I hear ya Novadude!!

Re: M20 wide box
 

Sammy,
4.56 and 4.88's are perfect gears for those little 302's.I still have the original 3.73's in mine and can say they suck.I don't even think that 4.10's would be any better.Nothing like a good set of low gears to wake up the 302,have some fun this summer.Just fired mine up yesterday for the first time this year,come on spring.

Re: M20 wide box
 

I got 4:88's in my car and love them.[put 4:88 in 1971]

Re: M20 wide box
 

4.10's are not really enough with a M21 Mark. I like a little more snot if you know what I mean. An M20 helps the .10's out BUT the .56's are better yet. Not quite ready for the .88's Paul but if we do a cam change............

I have to stop up and see you and get some 260 gas.
