DittoI voted LSx... because F**K YOU
BTW, I can't believe the pushrod 5.0 is winning this poll. You guys are boring!
Boost is great, but I have a lot of respect for getting it done N/A. There is just way more thought and effort that goes into a 650 hp NA 408 than there is a 650 hp bewsted 347. Plus, there is just that much less that you have to wrench on with N/A.
Of course, hearing the supercharger whine or the turbo BOV makes me giggle like a school girl, so I guess either works.I'd love a big W, but I'm kind of thinking about doing a Dart block 363 in my car, just because I already have all the 8.2" junk and that way I could throw all the bewst at it that I want.
coming from a ex lightning owner...
4.6> 5.4... just WAY to much stroke in those 5.4's
Just because one guy in a very extreme application (50 psi and 9000+ RPM in a 2400 lb vehicle if I understand it correctly) runs a 4.6L doesn't mean that it is always the better choice over the 5.4L.
There are also plenty examples of insanely fast 5.4s out there. Don't the MMR guys have some ridiculous 5.4 stuff?
Anyway, in a street driven N/A application, I'd take a 5.4 any day of the week, no brainer. The 4.6 is just too small to make any sort of respectable torque without boost. Even with boost I'd do the 5.4, it would be the same power with less boost, or more power with the same boost.
Im might be buying the intake for it this week Nik.Believe it or not, it is $150 bucks brand new from the manufacturer lol
dudeMy buddies car (my 98gt clone) is making around 330ft on stock heads and cams, with a single plane eddy. Compression and bigger 3.7" bore make a huge difference on the mod motors. which his is only 3.552 bore.
look into the rod ratio of a 5.4, the piston speed is stupid fast, and there is a reason they are doing a bigger bore 5.8 in the gt500.
it would be less hp with the same boost just more tq. We have done the 5.4 2v swap, and making 375ft is fun, but 235rwhp isnt, especially when the power runs out at 4200rpm. It belongs in a truck, the 4v navi motors are loads better though, but crazy heavy.
You should love high rpm N/A cars, you have that black one sitting in the garage lol

Nik has a high RPM black engine in his garage? Sure you're not confusing him with me?
I think you may have been on StangNet moderator-induced vacation for the bulk of my build, haha. Yea, my '86 is now a screamer, see my sig. Still working out some details, but should be a mid-low 12 car. I've been shifting at 6100-6200, but only to avoid the factory limiter. I'm going to pick up a quarterhorse this winter and raise the limiter and probably shift somewhere around 6400-6600. Not exactly mind-blowing RPM, but pretty decent for a stock bottom end.
I saw most of your build, and enjoyed it. It was late when i made my post because he said the black engine in your garage and i thought you painted most of yours silver or gunmetal or something. Thought he was talking about an engine on a stand.
In any way, RPM is fun, i cant wait to hear mine scream at 7000
Oooooh, gotcha. Makes sense now. I think he was referring to the color of the car. Yea, the engine block/bellhousing/oil pan are all painted a cast iron color.
nik, that blue sn95 I was turning 7100-7200 all day, just depends on the balance! stock rods and crank, probe pistons.
as for my dream engine build, I would do a 4.150 bore dart, with a 289 crank. 225cc heads, super victor intake, carb. and about 13.1-1 comp. and turn the bitch around 9k.
or big bore teksid, stock stroke, trickflow R's, huge cams in the 260ish duration. 14.1-1 with a carb. The nmra guys have been running 9000+ rpm with milder setups than this, so im assuming it would be crazy like this.
Im just under the assumption that there's nothing a LSX motor can do that the windsor can not...Thats why the windsor got my vote, Might as well keep it in the family.
