413 Crank

[Nacho-RT74]

does a 413 crank work for 451 stroker on a 400 ? as far I know stroke on 413  is the same than 440, but want to be sure does work.

If the crank is from a car with a 6 hole flange it is basically the same crank as a 440, but the one you have to watch out for is some of them were out of trucks and they use a completely different flange style with an 8 hole flange and is nothing close to what the 8 hole flange that was used on the hemi's, those cranks will only work with the truck style transmission.

OK, I didn't know about 413 with 8 bolts I thought just Hemis were 8 bolts. So I will be fine for a while is 6 bolts then

what "truck style" transmission are you referring to?

[Nacho-RT74]

it is basically the same crank as a 440

curiosity... if you say basically is the same than a 440 crank, what is the "difference" if there is some noticeable one.

[RD]

a forged 413 crank from a passenger car is exactly the same as a 440 forged crank.  Both are 3.75" stroke. journals are the same size on mains and rods.

"Look" for an early 413 Crank, to Identify by the "nub" that sticks out on the Rods throws, which differs from the 440 Cranks.

Yes the 413 cranks work for 451 builds.

reason I'm asking is because probably I'll get a 413 crank FOR FREE

The main thing you might be concerned about between the 440  and the passenger car 413 crank is possibility of a balance issue which i'm sure you will balance it anyway, otherwise they will work in place of each other just fine.

As far as a truck transmission style I am referring to is mainly the type of transmissions used in bigger 2 ton style trucks with a manual trans, they have a different type of flywheel set-up they use and of course alot bigger transmission. I hope this helps,
