Ya gotta be kidding...

The latest NHRA tech bulletin drew my attention to a Ford Cobra Jet engine that I wasn't familiar with, the "429 455/455". Since I have run a "real" 429SCJ I was interested in what a 2014 version was like. So I took a look at the engine specs and damn near fell out of my chair. OK, I am true blue FoMoCo but this engine is insane with a 455 HP rating. 429 CID, 14.9:1 CR(!!!!), 0.650 lift roller cam, 1800 CFM throttle body and NASCAR "D3" heads in a high deck Windsor small block package. It is essentially a stroked version of a NASCAR engine from a couple of years ago with the advantage of a roller cam, EFI and a monster throttle body. NASCAR engines are making 850 to 900+ HP with 70 fewer cubic inches and a flat tappet cam!

It wouldn't be cheap to build one, but with a 7.0 weight break a 2014 Mustang could probably run 2 seconds under in either BB/S(A) or SS/C(A) without breaking a sweat. 900+ HP in a 3200 lb car, yikes! Stop the madness !

I wonder if FoMoCo is going to do a 460 Windsor next year. They sure do like bringing back classic displacements.

I dunno! I bleed Ford blue, and that looks AWESOME to me!

Bill where you been??? The 2010 426 hemi challenger and the 2014 427/430hp COPO are basically the same as far as cr., engine size, camshaft specs, etc.!!

We have been talking to Kuntz about the Combo and you are right, it won't be inexpensive to build. If you are going to run FS/B with a Ford, its the Combo to run.

Should be a bad boy once you get it sorted out.

Now If I can just get those ping pong balls to line up right!!!

I need that 1800 cfm throttle body. I gotta get that for the Mopar. We only got 1600.

What I find more amazing than the "new 429" in the new Mustang is that Chrysler/Fiat found an engine combination that they never knew they put in a "limited production, not for street use" car five years after they built them. Now THAT has to be a "limited production"!

[Bill Harris]

Yeah, I gotta admit I haven't been keeping up with all the latest factory stuff. I have been looking at the Ford specs occasionally but haven't ever looked at the stuff from the dark side. The last Ford engine I considered was the 2010 352, but since my latest race engine efforts have left me broken and broke, I have pretty much quit racing altogether. I can't seem to stay away from Class Racer website though.

Billy, not only are these special cars out there, they are going to allow us to move the rear wheels forward to be the same as the Copo and SC Mustang. Now if we can just get the Injectors Tubes sticking out the hood.............

1800cfm is one big Throttle body!

Best I can find on Throttle body flow per size...

65mm Throttle Body 745 CFM - 3.125" OD
70mm Throttle Body 830 CFM - 3.125" OD
75mm Throttle Body 915 CFM - 3.125" OD
80mm Throttle Body 965 CFM - 3.500" OD
90mm Throttle Body 1170 CFM - 3.750" OD
95mm Throttle Body 1450 CFM - 4.250" OD
105mm Throttle Body 1520 CFM - 4.250" OD



The 2012 and 2013 COPO's have 102mm and the 2014 COPO has a 90mm Throttle body.(427 motors)

[Jeff Teuton]

The Mopar's use a 4 hole 1 3/4 in on the DP's which is the same size as 750 CFM 4150 series carb, but it is rated @ 1000 cfm. The 426 Hemi uses a 2" which is the same as a 4500 series base and is rated @ 1600 cfm. Course we are only flowing air. The Copo 427 single blade has a slightly larger area than the 2" 4 bore that we use.

Jeff, 2% rule?
