Stroker question

[sleepychallenger]

If you can put a 440 crank in a 400 and make a 451, can you put a 440 crank in a 383 and make something?

[NoMope Greg]

Yes - you get a 432.  Mopar Muscle did an article about a 432 stroker build a few years back.  Here's part 1:

You'll note that they got the crank from a 413, but the crank is interchangeable for all RB engines, so a 440 crank will be the same and require the same modifications.

Here's part 2, if you're interested.

right on. maybe i will make this my next engine build project

Seems like a bunch of work to end up with a smaller motor than a 446.

It does work. Gets you stroke and not much else. The bores are small and have shrouding issues, but they work. I'd still run the 440Source B wedge 3.75 crank first. Much less work involved.

[71chally416]

I guess the premise of the article is 440's are somehow scarce which isn't the case. That level of HP out of a 440 with reconditioned stock parts except for the pistons, big valves and some porting on iron heads along with a good cam and Intake is easy so I don't see the point.

Drew, pm me if you want / need a new forged 440source 4.15 stroker crank for your engine

i just want something different than what the majority of the croud is doing. i love my 383 and would like to run with that.

I could go pick up a 64 413 block I had stashed

would love to have that, but i dont think it will bolt up. 

[71chally416]

Why not? 

[sleepychallenger]

is it the same bell bolt pattern? i thought they were different

[Moparal]

Bolts up and can be bored to a 426

[go-fish]

Jump on it Drew! H-E-M-I !!!

[sleepychallenger]

ohhh  the fun we could have
