Any special advice on dropping the tank?

Looks pretty straight forward.

If the sticker is there, it will be really brittle, so planning on taking good pics before trying to remove it. Anything I can put on the glue to soften it before trying to pull it off?

----Lynn,,,Consider buying another tank if the sticker is well stuck and then store the original someplace safe. Many Corvette guys are doing this in today's restoration world.

----Once the straps are off rotate it down from the front. If possible it helps to remove the exhaust,,,at least one side...…..Bill S

Brain fart. CTU engine. Corrected my first post.

3.70 gears in the Corvette IRS diff , 3.73 is Camaro, Chevelle stuff. 3.36, 3.55, 3.70 and 4.11 are the possible choices here, with 3.36 being an M20-ONLY gear ratio in a '70 LT1 Vette, and not available with the close ratio trannies.

Pray for a numbers matching M22!!!!

Thanks Des, I am not up on these. What diameter tires were used? The LT1/M20/3.36 sounds fun.

Lynn........... was the tank sticker still there?

Awesome find. Dan and I have a 70 LT1 Convertible. LT1, M21, 4:11. All born with original drivetrain and documented. They are awesome cars and a blast to drive. Post more pics and if you need any reference pics or parts let us know.

Best,

Vettes run F70 -15's -

My LT1 has 3.55's with the M20 which is about the same effective first gear as a M21 with 3.90's - runs out nice and pulls pretty well from the hole.

The performance ratio with the M20 was 3.70
Economy with M20 was 3.36

Perf M21 4.10
Econ M21 3.55
Std M21 3.70

Thanks guys!!!

I love drivetrain calculations!!
