Why do you think some one came up with a 427 LSx or the 454 LSx, I bet other displacement would have been easier. Some of us are old enough to rememebr the old cars and some even owned them. You are right I am spending a little extra to have a 455, but if you are already shelling out your hard earned money why not get what you really want, instead of settling for almost. Besides I wanted an aluminum block since the LSx is stupid heavy and not going to be seen in any autocross car.
Actually for me no whips antennae, or hood birds, just these center caps.
They look a lot like these.

Do you know what cars came with those or what it stands for? If you are over 35, you might.
Some of us like the nostalgia in the cars which includes the displacement. Have a good look at the next Camaro, Challenger or current Mustang, you might notice they have a lot of traits from the old cars. It does matter to some of us and Detroit has noticed too.![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)

If the nostalgia is your thing, that's cool. In the end, the only person who needs to be happy with the money you spend is you.
BTW, yes I know what PMD is. No, I'm not old enough to have lived through the muscle car craze, but I certainly know what I missed out on.

I've just never paid that much attention to final ci. I've just looked at GM engines as big block, small block and Gen III. CI has always mattered less to me than HP. Except in the freakish circumstances where people have built incredible 283s and 327s for monster power.

As long as at the end of the day you enjoy your car.

Why don't ask us old timers for a 455, you'll get us excited!!!

If you factor in head gasket thickness, piston valve reliefs, CC of the heads actual measured cubic inch volume in the cylinders is going to be over 455"....so you still didnt *actually* reach your goal technically...
Paying that much extra for a cubic inch? Wow.

I am sure you know what you are talking about, but what does the cc's of the heads, gasket thickness, piston volume have to do with the displacement of a motor? They all relate to compression thats it.
Displacement is really simple (bore/2)^2 x 3.1415(PI) x stroke x # cylinders = CI
The only way to change displacement is to change one of the above, bore or stroke.
BTW bore and stroke need to be measured in inches for the above.
When you talk cc's for the heads that is metric for cubic centimeters. 1000cc's=1 liter

Is it me or is all the opinions that are needlessly given on the tech sections of this board kinda gay?
Damn I can see if someone asks for an opinion to give one, but when someone wants an answer on a tech question to get ridiculed is retarded to me.

A Pontiac 428 (67-69) was actually a 427. Why didn't Pontiac call it a 428? You guessed it - they wanted their motor to have its own divisional numerical identity. And yet a Pontiac 350 was actually a 354. In 1963, the Pontiac 326 was actually 330.
You can do the same today. Install a LS454 and call it a 455. Say it's Pontiac tradition.

So build a standard 428 and you'll have a Pontiac ci.

REVGTO, The Pontiac 428 was actuly closer to 426 c.i.d., but no way was Pontiac going to use the same engine size numbers as the hated mopars!!! And Olds and Buick had already used 425.
Now as for using a 455 inch engine, get the real Pontiac 455 and fix that car!

Uh what about a tall deck Warhawk 455 with LS1 24x crank, LS1 cam sensor location (-vs- LS2/LS7 cam sensor location) as well as the ls1 knock sensor locations.
Just a thought...
Then again I wanted a 389 based off of the L92 block, but I couldn't find anyone that made a 3.75" crank for the LS1 based motors....

The point is, a lot of number fudging went on, so why not fudge your own today?

The Pontiac F cars have a longer history with Chevrolet engines in them. The Firebird hasn't used a true Pontiac engine since 1981. So why not honor the heritage of the Chevrolet engine in the Pontiac?
