Actually new, or will used do? You're talking about at least a $100 difference. If it were me, I would pull one off a 2001 at the junk yard for $30 and clean it up.

 

Well......it'll be new to me LOL!!! The cheaper the better..

 

Not always.


If you are going to the JY to get an upgraded intake manifold, you might consider doing a bit of work to it to improve it even more. You will also have the new engine that you can work on before you install it.

Port-matching and polishing the intake and heads can result in better fuel economy and power and all you'll need is a bit of elbow-grease, know-how and some inexpensive tools that you probably already have. A dremel or a drill, for example....

 

Well said this sounds like the best bet in my opinion I plan on doing this soon.

 

Port and polish is an old school hot rod trick. Years ago I remember reading an old Hot Rod mag test and it showed minimal gains at best. Still, worth doing as all it costs is time.

This has my eye and I plan on calling tomorrow.

If I can get something like this with a c/r of 8.8/1 or so I'm in business. I will let yall know what I find out.

 

Personally, there's no way I would order that.

First, that description is pretty weird. 240 to 280 hp? There's a 40 hp variation in the power they get out of their engines? If so, something is going seriously wrong with some of them. I think the likely explanation is that they have no idea how much power their engines are producing, and I would be surprised if it were anywhere near what they claim. Furthermore, they're listing that motor as a 4.0L engine, not a 4.6L or 4.7L as is usually the case with strokers making that much power. I don't think you would actually receive what you're expecting.

Second, they don't have many reviews on line, and the few they do have are either complaints or lawsuits. Even if there were no negatives, there's no way I would buy an engine from them after reading the odd things on their site unless they had a good reputation. They don't.

If you want a higher horsepower engine, buy a stroker from one of the established builders with a decent reputation. For another $700 you can get a 4.6L from Golen. I have one in my 2000, and I know it can output 274 hp because I have the dyno sheets to prove it instead of just some weird vague claims on a website. Plus I have a 100K mile warranty. There's also a Mopar 4.7L stroker that has similar specs for about the same price.

Or just stick with stock, but from a reputable builder. Those guys you linked just seem too hinky.

Many thanks to you extrashaky for doing my due diligence. Your concerns were among those I was going to ask about. I can cross these guys off my list.

I think I might just go talk to some local shops about building my motor.
