What is the stroke on a 400 crank?

The original 265ci small-block used a 3.75-inch bore and a 3.00-inch stroke. When the time came to design the 400, Chevy engineers had to stuff a 3.75-inch stroke into the 265’s same block architecture.

Do you have to bore a 350 to make a 383?

You can not “bore” a 350 and make it a 383 you have to also “stroke” it (meaning a longer stroke on the crank). A 350 crank is 3.48″ stroke and the common 383 stroke is 3.75″. This is where the extra cubes come from.

What is a 383 stroker?

A 383 stroker has a 0.030 over bore of the stock 350, giving you 4.030 as a bore diameter. Putting the 400 crank in the 350 increases the stroke to 3.750. Other than that, all the other dimensions stay the same. If you do the math, you will get 382.6; round up and you have 383 ci. Refurbishing the Rods.

What’s a 408 stroker?

The 408 Ford is an excellent choice for those looking for a Windsor based stroker engine to fit in place of an existing 351.

Is there a 60 over bore on a 350 Block?

As many have stated previously there’s nothing wrong with a .60 over bore on a 350 SBC. Now on a 400 SBC that’s pushin it kind of close. Mainly because the 400SBC is a Siamese bore unlike the 350 SBC which is a standard bore.
