i am looking to put a 383 stroker or a 396 stroker which one is better and y?

 

A 396 has 3% more displacement than a 383, offering approximately 3% more peak performance, assuming you assemble a well-matched set of components.

Parts to build a 396 are going to be a lot more than 3% more expensive than parts to build a 383.

Which is more important to you?

 

go 383, its not worth it IMO for the added rod to cam and rod to block clearance issues.

 

Head selection is FAR more important than that small displacement difference and an area where a HUGE number of folks screwup their stroker builds.

ALL the air going in and out comes and goes through the heads, if they are not right the shortblock can't do much to fix it.

 

Displacement isn't the whole story.
But overall, I do agree with Jake, the 383 is a much better way to spend your money.
There's a reason you see so many guys with many years of experience behind them running 383s.

Like Dwayne was eluding to, it's the complete package, not excess in any one
component that makes (or breaks) the motor. Having a bullet-proof bottom end is
not terribly useful if you run out of money and have to skimp on the heads or valvetrain
or pick something that just doesn't fit the combo.

The longer stroke means more low-end TQ, it also means more block clearancing and more exposed cylinder wall.
Expect to be welding/filling the block and/or selecting special components to reduce/avoid clearancing issues.
The longer stroke also eats deeper into the piston skirt. But the 396 can handle "more" cam, and compresses
the curve you'd see in a smaller displacement motor.

So, "Which is better?" turns into "How fast do you want to go?", "How much do you want to spend?"
and "Are we talking about a street car, race car, or somewhere in between?".

Here's a computer model example of a 383 VS 396 using identical heads, cam, etc ....
Take it for what you feel it's worth, the idea is simply to show what the increase in displacement does to the curve.

Inches are inches, period. As for cost, a 3.75" stroke crank costs the same as a 3.875" stroke crank. As for clearancing, get the right rods and it won't be a problem. Crower Sportsman Stroker rods are the absolute best for clearance (they are a forged I-Beam design with short bolt heads). H-Beam rods tend to require much more block clearancing. Go bigger, you won't regret it. Plus you won't have to rev it as high, so it will last longer.

 

Been discussed a million times, as you already know. I would build a 383, but not a biggie either way.

Build a 383 and put a good set of heads and a nice cam in it. I see far too many people asking if they should put a hotcam in their 383 and then wondering why it only makes 360whp.

 

This is his first post??

 

There is not a post requirement for search - and this site has a very effective one .

Enough posts, opinions, and information on the topic to make your head spin.

 

thanks for the help im going with the 383
