...it will be dead nuts OEM reliable, make 400+rwhp no problem and spin upwards of 7500rpm.
You just described an LS motor. Well done!:lol1:

You forgot expensive, and upgrading it will be more than the LS1 and way more than the SBF. You can build a nice 420 HP SBF engine that will live a long time for well under $4k (especially if you buy some parts used).
The price for an LS will vary as you can buy a take out and modify it or start from scratch. I bought an LS1 with spun rod bearings and it came ECU, harness and the intake and oil pan I needed. I rebuilt it for track use and have about $4k into it total, and that was finding deals on parts along the way. It is overkill but it is bulletproof. On top of that is new accessories, a starter, all new sensors, an accusump, and other odds and ends, and you are talking around $5k.
Don't get me wrong the Coyote is a nice engine, but if you a building a track car it is probably not the best choice.
The coyote is not really any lighter than a SBF or a LSX with an alumnium block. They are all about 450 lbs.
OP - is this for an AI or AIX car? Or just a reliable open-track engine? Reason I ask is because if it's AI you would have to be careful not to make too much power otherwise you'd be bumped into the AIX class which you would then be outgunned.
Well, not sure if the car we are talking about is a street car, track car or all out race car. I said new for new prices of an LSX or Coyote are basically the same. Weights are also basically the same, I still think that the Coyote is 15lbs lighter :-D
Actually you need to consider other things when you put an LSX in a Mustang from a decent K-member, bellhousing, headers and a lot of small crap, specially in a street car. The coyote bolts to existent bellhousing and the headers are $500. The result: 400 rwhp as reliable as it can be.
If it is a Fox, yeah, SBF will be a lot easier and cheaper!
Thats fine, but don't come crying to me when you want to do heads and cam(s) because you are getting forcibly passed out there

What? No N/A mod motor option. (not coyote)
Buy used. Mod motors are plentiful and there are a shit ton of parts out there for them now.
just open track- no class restrictions
i'd also go with a coyote engine, but only because it sounds cool and smacks of the old days and racers like foyt, andretti, etc. Not a very rational reason to choose, but that's never been my strong point.
