Tranny Question

**SamLBInj** · #1 08-10-2005, 06:30 PM

Would it really hurt the value or basic originality to a car if you put a M20 gearset into your m22 trans?

Why take a good box apart? I would just do a M20 for the car and take your original out and put it away.(JMO) I have a spare, fresh M20 on the floor, just to lazy to swap my original M21 for it. I need Mark, Darren, or Dan to be my neighbor.

Not at all. I believe any change you make to your car that is reversible is fine. In your case, I'd suggest you box up the old gears and provide them to the new owner if you should sell it. My L78 velle came with 3.73 gears in the rear, but POP and BS called out 4.10. 4.10 came with the car when I bought it. I returned them to the rear shortly after purchase as that is what I wanted.

I agree, but perhaps I'am missing something here. Unless you don't like the distinct whine, why change out the M22 gears?

Maybe he wants a lower first gear and doesn't want to change his rear.

Good Question Sam. Just swap away. Who is going to look at numbers? or casings? Unless your going to be showing a car Nationally in which number verification is keen, go for it. If your going to drive your car(s), take all numbers matching parts out, throw them in a corner of your garage and drive without worry.

You are correct, I really like the M20 gearset in the SS with a 331 posi and since my Z/28 needs new sequencers(Sp?) I was going to put the M20 low 1st gear in, coupled with the 4.11 posi rear it may be a little quicker...Im currently running an LT-1 with 11-1 pistons, worked 202 heads, chevy off road cam, edelbrock tm1 manifold,holly 780 carb,Unilight ignition, Alumicoat headers and 4.11's...anyone try a combo like this and see the difference? I was thinking of 456 gears but the tranny change will make the difference...I decided that I will never sell this car so having pure originality really wont matter..Maybe I will just put the tranny away and build the one I want to try...

Thats a 12 flat car with 9" tires and open headers. Should run around 112 mph.
