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.
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.
67 Chevelle convertible, 138 vin, original 4 speed, bucket seats, Marina Blue with black interior
