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.
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.
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
