My Crazy Idea for a 400M

I was thinking about what to do for the new powerplant i plan on constructing for my car and I've established some basics that I want. It will be carbureted with a Holley 4165 spread bore, it will be 383ci displacement and will maximize torque. Since I started planning I was always just thinking about stroking up my 351W block but then it donned on me that I could destroke a 400m to 383 and have a huge rod ratio. i know what you all are thinking Why would you want to get rid of cubic inches. I don't really know this idea just kind of hit me so I thought i would throw it to the internet and see what other people thought. So give me you input constructive, criticizing or otherwise.

Re: My Crazy Idea for a 400M

Well if your passionate about doing it then go for it. It will be a torquey beast.

The parts for the Windsor are more plentiful and cheaper.

The amount of performance intakes or intakes in general for a 400M is low. Alot of the other parts are the same as the Cleveland.

I think the block clutch housing bolt pattern is different between a Windsor and the M series too if that is important.

Re: My Crazy Idea for a 400M

ya it's just something that popped into my head if i'll actually do it is another thing depending on if it's easier to stroke up a 351W or stroke down the 400M I know the destroked 400M will have way more torque due to the larger rod ratio. It all depends on what i can find parts for easiest.

I would love the 427 but it's not a very good long term engine the pistons are so thin they like to move around in the bore. But if i had the money and i didn't need this car to last for ever I would totally go with the 427.

Re: My Crazy Idea for a 400M

If you take a 390 and put a 352 crank and longer rods in it you can make it into a 360. The longer rods do not give the 360 more torque than a 390. Stroker engines have a longer crank throw....shorter rods...= more torque. Less crank throw...longer rods= less torque

Stroke your 351 Windsor.
