[DeTomaso] Engine Choices

[Corey Price]

Yes, this question is circling in my mind.  I have considered many different things.  The current favorite is a 351w 9.2 deck Boss block with Trick Flow Cleveland 2V heads and a Trick Flow Track Heat 4 bbl intake (verified with TFS that it can be milled to fit a 9.2 deck Windsor block).  Stroked to over 400 cubes with no oiling issues, readily available Windsor parts, Cleveland heads, off-the-shelf headers, etc.  

The other favorite is a Coyote.  You can build them to 500 hp by just porting the heads, new cams and phaser limiters, and a Boss 302 intake.  Great power under the curve.  7000 RPM is no sweat.  The Boss version is verified stable to 8400 RPM but the computer apparently isn't fast enough to go much above 7500 RPM.  The Cobra Jet version apparently uses a different crank wheel with less teeth to go up to 8100 RPM.  

Gary, you need to drive a new Mustang GT.  The variable cam stuff makes that Coyote perform like a much bigger engine down low.  Pick a gear, and there's power available.  No, it's not 400 lb-ft at 2000 RPM, but it's not bad at all.

The variable valve stuff can make the engines sound different, too.
