I will take my time doing parallel and concentric and will update again on how it drives. Iíll call Jody for all the miscellaneous parts I need for it to work. Thanks fellas!
Don't forget to check your driveline/ pinion angles.

Re: McLeod Muscle 5 speed install.

Curious; what bearing race number is on the countershaft front?

Where at & how much?

Enjoy! <img src="https://www.chevelles.com/forums/images/smilies/thumbsup.gif" border="0" alt="" title="Thumbsup" class="inlineimg" />[/QUOTE]

I bought it from Jegs. $2800 plus the reverse speed drive at $140. They have a 60 day return policy. So that gives me plenty of time to get it installed and sorted out.

Hey Dutch. Thanks for mentioning that. I downloaded Tremec’s angle app to help with that. But the McLeod is shorter than a TH400 and sits on the factory cross member with the trans mount. Do you still anticipate the driveline angles being off? No disrespect meant. Just trying to get educated. Thanks.

The trans is still mount in the car and I won’t be able to get to it till later in the week. So I couldn’t tell you for sure. Here is one of the pics I took that you can barely make out some numbers scribed on the front of the counter shaft. That might also be a good question for McLeod’s technical staff. I’ll let you know what it is when I get to it. I have to believe this is based on the WC T5. Thanks.

Re: McLeod Muscle 5 speed install.

I really wanted to try this trans. Glad it fits in your '70...it looks like it won't fit in my '67 with a console. The shifter is not in the center on a '67... Dammit.

Out of curiosity what are the gear ratios?

McLeod make an makes an offset shifter that should work for 64-67 stock shifter locations.

Those wide ratios should work great with your 3:31 gears

I thought so too. I did the math before I bought it and my SLR will be real close to 10 at about 9.76. It will make my 3.31s with the 5speed act like a 3.90 rear gear with the M20s 2.52 first gear.

Re: McLeod Muscle 5 speed install.

Yes looks like a almost perfect combo. Way easier on the engine on the Interstate and the mileage should be better also. Keep the installation pics and info coming. Thinking about doing this with my 66 Chevelle that currently has a M20 in it with 3.73. gears.

With the old setup, cruising at 70mph my RPMs were right at 3000 with stock Wide Ovals. With the new setup it will be right around 1900.

My camshafts rpm range is from 1800-5000. So 1900 is just squeaking by. Should be fun to sort this all out.

The LS1 T56 from 98-02 Camaros is also a great trans for Chevelles. It's what I'm installing. The Magnum T56 is a bit larger and requires cutting.

My 6th gear is .5 - so my rpm's with 3.73 gears will be about the same as yours.
I've seen magazine articles where they didn't have to cut the floor for this trans - only the shifter opening.
Some on here dispute that. I will keep you posted as I'm installing mine this year.

If your cam peaks at 5000, it will have no problem pulling in the 1800-1900 rpm range.
I'd like to know what gas mileage you can squeak out of this setup.
