I am swapping the motor out of my 87 iroc and am teetering on changing it over to a 327. Any recommendations on components that would compliment the 327 to the maximum potential?

Well it is more than likely going to be a carb..just easier

torque_is_good

do you presently have FI? If so, the 305 or 350?

Why would you want to give up FI ?

Apeiron

0.23" more stroke. Or even better, 0.5" more stroke.

I'll add in .030 bore to compliment that .5" more stroke.

Apeiron

The overbore is even optional.

True, but I believe the .030 overbore is more common then not

Let's put all the romantic 60s nonsense BS out of the way, and THINK, using the BIG head, instead of the little one:

OK, so people looking for more power, often put a crank that gives .25" more stroke than their existing 350, into their 4" bore block. Got the picture clearly? More stroke equals more power. Before we go on, is there any word in that last sentence that is unclear? Anything I can explain more fully? OK fine.

So a 327 is a 4" block, with .25" LESS stroke than a 350. Got that? Same bore, less stroke.

Now let's go back to that tricky sentence up there:

More stroke equals more power

Now explain to us all clearly and articulately, WITHOUT invoking the stupid "rev it to the moon" nonexistent fantasy, how reducing the stroke is an "improvement". Remember, NO "revs higher" is allowed, because IT'S A LIE.

If you can do that, i.e. explain how you can take a 350 and make it better BOTH by increasing and by decreasing the stroke, you're ready to downgrade your motor from a 350 to a 327.

woooh take it easy sofakingdom...nobody is saying that the 350 isnt a more powerful motor...thats one of the reasons the 350 came out after the 327 b/c it was an improvement to its predecessors...My goal isnt to have the most powerful car on the road im not even gonna attempt it b/c it wont happen. Im just looking at doing something different. The 327 is a great motor and can still produce as much power as I would ever need. However a concern i do have...would i encounter any problems with the 327 if i have a 700R4 trans and a 4:10 rear?

No more problems than you'd have with anything else. It's just another SBC.

More stroke equals more torque. HP is relatively the same but the displacement difference will move it around in the powerband. Larger engines make more HP at lower rpms providing all the other parts are identical (Cam heads etc).

The 327 will run just fine in your car. It's a better option than a 305 but not as good as going right to a 350. As mentioned above, it's just another SBC.

Torque is what you feel driving stoplight to stoplight. HP is what you feel when you pass a car at highway speeds.

Take WHAT easy? The TRUTH??? How am I supposed to do THAT?

The issue isn't whether a 327 is "a good motor"... the question is, why spend extra money and do extra effort to downgrade a better one to it, when you already have the better one?

If the 327 (or 283 or 305 or whatever...) was all we had to work with, we'd all be talking about how great it is and you can do this or that to get more out of it. But that's not how it is. There's this OTHER motor out there, in FAR GREATER numbers, which means it's CHEEEEEP, that delivers MORE of everything; any other SBC will cost more to build than a 350, and most will deliver LESS.

THINK of it that way too: spend MORE, get LESS. Now that's a true marketer's dream, eh? Is THAT the kind of "different" you want to be?

THINK of CID as being an "amplifier" or "multiplier" for your money; so in what universe does having LESS get you MORE?

The basic hot-rodding equation:

$$$$ x CID = FUN

It's just that simple. Don't shoot yourself re-inventing the wheel; believe me, PLENTY of people have already been there and done that, and all got the same results. The basic equation there says that for any amount of $$$ you spend, you get more FUN if you have more CID; or, to get to a given FUN level, the more CID you have the less $$$ you have to spend; or, any number of other similar logical outcomes. It's all logic.

As said, the 327 presents no more problems than any other small block, except losing more races than necessary.

I would say, the one part you could use in a 327 to bring it to its maximum potential, would be a crank with at least 3.75" of stroke. After that it's all gravy.

How many ways can we THINK THINK THINK THINK about this and keep coming to the same conclusion, before it sinks in? Is there any aspect of anything I've said that's not TRUE, or that you simply don't understand? I'll be happy to go back and explain more fully if you need it.

Which is why it won't be "different".Guys build 305s to be different,put 283s in to be different,but you know what?At the end of the day,when you raise the hood,NOT ONE DAMN BIT DIFFERENT THAN ANY OTHER SBC.
Unless your posting engine specs on the aircleaner lid,spend your hard earned cash on power,paint the car pink,and have a "different" car that actually runs to the par to match the cash spent.

A friend of my fathers has a Cobra kit car with a 427 BBF in it and I've never seen anyone ask him why not a 460? The sound that motor makes through the side pipes makes you forget all about statistics.

If you want a 327, do it. It wont be the first time someones done it and it won't be the last. But the cold hard truth is its cheaper to build a 355 and great bang for the buck to go 383. To make good power on either engine you need to spend money on a good set of heads.

Actually, I just got finished with a 305 to 327 swap in my car.
