2014 COPO Engines
 

Wonder if anyone noticed the GM 2014 COPO Engine Blueprint Specifications now posted on the NHRA web site?

Couldn't help but notice that GM went from 3 engines in 2012 and 2013 to 4 engines in 2014 including an all new 450 cu in version rated at 460 hp! Sooo..If you want to run the Shootout and don't have a 2014 COPO with a new 450 you will obviously be leaving a bunch on the table.

Seems to me like all the 2012 and 2013 427 COPO's just got penciled out of competition at least as far as the shootout is concerned unless the powers that be decide to give a weight break to smaller engines, and we all know what kind of complications and infighting that can bring in to the mix.

Wasn't there 20 or so 2012 and 2013 COPO's in the Indy shootout last year? On the surface it appears that number will diminish unless these guys have the ability to change their cars to a 2014 and pony up for a 450.

Mike - I think you'll find there will be no shortage of '2014's' at the track this year .

Re: 2014 COPO Engines
 

Wow. 450 cubes. Going to be a monster after a builder gets there hands on one.. Heck... Going to be a monster from Chevy...

Re: 2014 COPO Engines
 

Jack,

I'm sure you're right about no shortage of 14's showing up next year. Whether or not many will be equipped with 450 cu in engines remains to be seen.

However, what about all the 12 and 13 guys that liked running their 427 cars in the shootout? Will they convert to a 14 and invest in a 450 or just run their cars in the class in which they choose to run in Stock Eliminator? Since the shootout is only contested at 3 events per year it's not that big of a deal I guess.

The other thing I noticed is for 2014 is the 427 engine is rated at 430 HP. GM seems to have gotten around the 445 hp factor assigned to the 12 and 13 automatic cars by changing the throttle body to the 3.545 used on the 350 and 396 instead of the 4.02 used on the 12 and 13 cars. How much the smaller throttle body hurts these engines remains to be seen.

Mike - I'm sure the GM brass didn't want to make any of the '12 or '13 cars obsolete but you're right - they were O for 4 last year and I'm sure they'd like to fix that as the whole point of being involved is to win races -- kinda like the old attage "win on Sunday / sell on Monday" .Both Ford and Mopar have ringers in this game and Chevrolet wants an equal playing field .Their new 450 might give them a chance for a Sunday Wally ..........Who remembers the runner-up ?

Re: 2014 COPO Engines
 

Will any of the new COPO engines have direct injection like the 2014 Corvette?

Re: 2014 COPO Engines
 

Tony, Chevy said not in 2014 or 2015 we will have to see after that...

Re: 2014 COPO Engines
 

The Mopar 426 Shoot out motor was made off the 427. Same bore, same stroke, Copo has slightly larger throttle body, same compression, so we will get 450 also. I am hoping there will be more than 3 shoot outs. I am hearing about 6 this year.

Re: 2014 COPO Engines
 

Kudos to 6 races instead of 3 Jeff. I love to see heads up racing but I knew this would happen with the 450 deal as soon as GM announced it. Obviously Mopar and Ford will follow suit and everything will be right back where it started.

Looks to me like everyone should have been happy with things the way they were and kept it to the 427 deal so everyone with a fortune invested already didn't have to start over with their engine programs in order to remain competitive.

Not to mention you will obviously have to have a 2014 car in order to run the new engines. Oh well too late now. Looks like the 450 train has left the station.

Re: 2014 COPO Engines
 

Seems to me that if you're not winning races you have to move forward and build combinations that have a chance of success .Yes , many of us have the 427 deal but you can't change the specs and they just aren't enough to play in that arena .But they do make a very nice BB/SA and CC/SA car .

Re: 2014 COPO Engines
 

It seems to me that the problem with the 427 is the weight break being at 450 for the shootouts.

For the regular classes, I think that Chevrolet has done a very good job of looking after the older N/A combinations.

Re: 2014 COPO Engines
 

Mr Adams is this going to be a plan for the BODY IN WHITE???

Re: 2014 COPO Engines
 

the 450 is a .100 stroked 427, same bore od 4.125, with mechanical roller lifters and they must have changed the head because there is a different part number. Fun to own one. Dyno

Re: 2014 COPO Engines
 

Different piston config, more cam, more intake runner volume, bigger valves, more rocker ratio, etc. About the only thing you can use from a 427 are the rods, the manifold and throttle body, and the block.

MK

Re: 2014 COPO Engines
 

I think it would end up more like this.

Re: 2014 COPO Engines
 

Nope...same exact block with a 4.200 arm, and the manifold and throttle body are exactly the same as the 12 and 13 427's.

MK

Re: 2014 COPO Engines
 

Understood, but I am sure that we will see this combination "evolve" a little before it sees an NHRA event.

Re: 2014 COPO Engines
 

Started the process today to get that .200

Re: 2014 COPO Engines
 

On your COPO???? :D

Re: 2014 COPO Engines
 

On my Mopo. 2.30 intake 1.70 ex. big new intake 699 cam 16 to one compression

Re: 2014 COPO Engines
 

That ol truck motor might run pretty good now! ;)

Re: 2014 COPO Engines
 

Anybody noticed the specs for the new 350-350? 265cc intake ports? Dang! Should make a lot upstairs, looks like maybe much better engine for a stick car? 1000 RPM Stocker. LOL

Re: 2014 COPO Engines
 

Yup I noticed them Ed!

This is an interesting engine indeed. 4.125 bore with a 3.27 stroke is the best way to achieve power with the 350. 6.300 long rods and 2.20 intake valves to boot...

Wish I had stuff like this when I raced Modified!

MK

Re: 2014 COPO Engines
 

Sounds like a Comp combo.

Re: 2014 COPO Engines
 

The 350/350 combo has a 2.165" intake valve for both 2013/2014.

Re: 2014 COPO Engines
 

Those 265cc intake ports suprised me. Not sure how that would work with an automatic. SS cars could fill them if needed. Stockers would be stuck with then.
A Stocker with a 7500 RPM 7" converter? LOL

Re: 2014 COPO Engines
 

Ed,

What the hell is a converter??>>LOL

MK

Re: 2014 COPO Engines
 

Ha! Yeah, don't guess that would be an issue for you. :-)

Re: 2014 COPO Engines
 

Very close to what I ran in C/A.

Re: 2014 COPO Engines
 

Probably so Scott but I bet you had a bit more than .535 lift.

All kidding aside this is a very-very good engine on paper.

MK

Re: 2014 COPO Engines
 

Can we request a new part number with a fresh cylinder head casting while your at it?

Re: 2014 COPO Engines
 

Super Stock doesn't have that limit. Better have a good source for valve springs.

Re: 2014 COPO Engines
 

C'mon Mike,,, snap one of these up and get back in the game. Then come out
on the Western Swing and win Seattle again!
Danny Durham

Re: 2014 COPO Engines
 

Ed,

You're right! This is even a better engine for SS....Maybe the heads are too big for a Stocker?

Danny...Man that sounds like a blast and I would love to do it!

MK

Re: 2014 COPO Engines
 

At least in SS you can fill them the size you find to be the fastest. In Stock I doubt you could get by with intake ports full of epoxy. LOL

Re: 2014 COPO Engines
 

If you over bore the 450ci will it be in the next class?
Dan

Re: 2014 COPO Engines
 

No.

Re: 2014 COPO Engines
 

I was wandering about this because one FS class is 450 and less and the other is 450 and more ci . Have I got the size of the engine wrong?
Dan

Re: 2014 COPO Engines
 

They go by original CID. Even if over bored its still a "450 CID" engine.

Someone correct me if I'm wrong.:D

Re: 2014 COPO Engines
 

I asked Bruce at the NHRA the same question, because it is not clear. This is his answer.

"Factory Showdown is treated the same as base Stock or Super Stock. Factory cubic inches is one number. we would not use an overbore number."
