One day Lovely setup....

One bit of marketing advice... not sure if you want to continue calling it a "value" motor. Most people tend to associate that work with cheap parts or sub-standard assembly when in fact your shop and your work is anything but. Yes people can spend tripple that for a C5-R based motor etc, but there's nothing substandard about it.

Reason I say this is because someone brougth it up in another thread and some members made allusions that if you used a $7000 shortblock it'd surely break down the road and that the only way to get a "good" motor was to spend tripple that.

Thanks for bringing that thread to my attention. I posted.

We call this our "Value" engine because it is assembled with cost in mind. We DO NOT call this our "budget" engine because budget implies cheap parts. I think Value implies good parts at reasonable cost. Not the cheapest, but still assembled by some of the best technicians in the world.

 

Very cool package...I would if I could.

 

thats awesome

 

What kind of a warranty does this come with?

 

someday maybe

 

curious too.

 

Working on putting one down on paper.

 

That is an aluminum short block correct? I didn't see that mentioned explicitly. Thanks!

 

Yes, a sleeved LS2.

 

What kind of power would you rate the block for?

 

Thats something you just can't put a number on. Anybody that does, ask them how they know that.

 

With all the best options .... whats max recommended redline ?

 

7000rpm assuming your valvetrain can handle it.

 

So you can't recommend a safe power number to rate your block for? How would anyone know what the limit of their bottom end is? Take a stab at it and go? You have to have some sort of idea.

 

I don't know what the limit is because we've never failed one. We have customers running 700+hp so far.

 

HP numbers are only good for bench / bar racing and braging, not racing.

 

That was the answer I was more or less looking for.

So you must have a stock motor Corvette since more power means nothing, right?

Call me crazy, but I'd like to know what a product's limits are before buying. Especially if I'm going to drop over $7,000.00 on said product.

 

When we fail one, I'll call you.


Call a company that says "good to 1000hp" and ask them how they know that. Sounds like somebody's opinion to me.
