Y-blocks were stock bolt in for 55-56...

It would be fairly simple to build a 450+ inch FE that looks like a 352. Torque monster time. If I had a '54 Merc, it would definitly get a y block. Might be 340" with Mummert heads a mild cam etc, but a Y-Block for sure.

Here's the other question ...what about an automatic behind , say , a modified 292 ? My left leg isn't " clutch friendly " anymore I'm afraid .  Is a C4 the way to go ? ..and can you get a converter with higher stall speed to launch the car better ?

If you want to do some serious racing a C-4 or even a race modified power glide is an option. For occasional racing and street fun I really like my AOD. I'm currently running 3.80 gears and cruise at around 2000 RPM at 60. I plan to put in a 4.10 soon. You get great gears out of the hole but good cruising with the overdrive. Chuck

Chuck , any racing I would do would be serious for that moment , but the car has to be streetable . A 4:10 would be my limit ....ran a 409 Chevy with 4:88 gears on the street when gas was cheap back in the day but , really , it was too much .....top end was only about 100mph but it got there in a hurry ! Ate plugs like no tomorrow .

I saw that somebody had a "C2" in a 57 Ford ...never heard of it , maybe a typo ? , or is that what they called their old 2 spd auto ?

TJ, Remember the AOD is an overdive unit. The effective top gear is going to be multiplied by the OD ratio in the transmision. In the case of the AOD it's .7. So the 4.10 gets multiplied by the .7 and you wind up with a 2.87 ratio. You get the advantage of the 4.10 in the lower gears with a reasonable highway gear in Overdrive.

Your top end will be well over 100 with an od assuming the engine has the power and if you are going to swap to a transmission that doesn't "bolt up" there is no sense in doing anything other than an od transmission.

I take it the AOD is a 3 speed ?

I think the Merc/Monarch is out of the picture . More realistic ( price for what you get ) would be a 55-56 F1 or F100 ...whatever they called them at that time ...even a Merc pickup if they were still being made .

I really like the 57 Ford hardtop but think it will be too pricey in good condition ...just the way the market is . I'm too old for a project car ....been there and done that in my yoot

I would call the AOD a four speed, it has 4 forward gears.

From an economical standpoint I would go with the Y and over drive, the FE you will get around 10 MPG, the Y you can get upwards of 20 +, figure that savings into the cost of the build and the Y will come out ahead after a couple years of paying gasoline prices.
