440 rods and ci

[cwhubb]

What increase c.i. wise, if any, will 440 rods yield in a 383?

None.

 

[beanhead]

Factory 440 rod length is 6.760", factory (B) 383 rod length is is 6.358", dang near a 1/2" difference....you can't just slap 440 rods into your 383.

 

[Cranky]

You can do a stroker 400 but you gotta research it a bit......

You get a displacement increase from a bigger bore, or a longer stroke , or both.
Rod length has NOTHING to do with cu.in.

You can put a 440 crank in a 383 and get a 426, but that dont make it a Hemi.

thank for your answer, but please stick to the subject. by the way, yes you can if you get the pistons from diamond and the pin end is 990.

Wow

wth does have to do with the question, you're chasing rabbits. you can marry a 6ft 130 lb woman with a super model body too but that doesnt make her any less ugly either.

The stroke of the crank and the volume of the bore are what decides how many inches you have.

really, I thought a longer stroke used more of the cylinder and that increased ci

 

[Sahara]

If a rod is thirty inches long or three inches long it only moves as far as the stroke of the crank moves it.

 

[cwhubb]

correction, I meant to say a shorter rod

thank you thats what I was looking for

 

[Sahara]

Same thing. Regardless of the length of the rod it only moves as far as the stroke.

 

[ruffcut]

Yes, longer stroke as in the crankshaft! ruffcut

 

[cwhubb]

thank you all, question is answered

It will increase RPM capability. Potentially all around torque as well.

Yes, a longer stroke does increase cu.in., but that is done by changing the crankshaft, not the connecting rods.
All a con rod does is connect the pistons to the crank,, it has nothing to do with displacement.

It will change the compression of the engine... Instead of compressing Air & Fuel you'll be compressing Iron & Aluminum....
