Dont believe any one has purchased it. JBO always seems to be high in price.

 

so i'm a little confused. do you send in your old block or are you getting everything straight from them?

i only ask because i looked up replacement motors from other dealers and they are about 4k

 

why is there no dyno's? i'm curious as to the power it makes, but JBP is fairly reputable, and they do have a tremendous amount of ecotec experience.

 

I made a thread about this last week and non responded. You better off buying a block and building it yourself

 

you send in your entire engine, and they send you the built one.

 

JBP works on a "core exchange system". This eliminates core charges. We ship you your replacement engine, upon receipt of your old engine. If this does not fit your schedule or your preference. Please contact JBP to purchase "out-right" a core and to find out more information concerning this procedure.

 

If you got the money. JBP stuff is superior, but their customer support sucks *****. It say allow 1-2 months to build. More like 1-2 months looking at the crate, 1 week to open the crate, 2 weeks of vaction, 1 week to look at the engine out of the crate, 2 weeks to pull of the head off, 1 week to figure out it is a L61 and not a LE5. 3 weeks to get LE5 engine. 1 week to pull head off. 2~3 months to finish. 6~8 months.

 

yup , because it takes 4 months the recieve headers that are already built

 

 

it isn't gonna give you 800hp straight out of the box, but it will be capable of handling 800hp right out of the box.

 

No one that I know of ever purchased one for j-bodies either.

 

So, this engine build of theirs makes about 300WHP without forced induction?

 

i doubt 300whp w/o FI.


I think JBP did a...paper build.

they say "Ok...these parts would work....so lets make a "engine"". then wait for you to buy it.

 

Thats what I thought but their site claims 300 WHP and no where does it say anything about a turbo or supercharger.

 

The key word in the engine description is CAPABLE you still have to do everything else to it. ie bigger blower or turbo, n2o a tune. All they do is build you a bottom end that an handle that HP. I also do not see anything about head or valve train work. Like Cams, springs, or valve's.

 

Thats what I plan on putting in my car if/when my motor goes........assuming I keep the car that long.

 

if i did this, might as well have them do cams and some other things too.

 

yea, they have a head package too. they sell them in stage. search the site

 

This I know but that is not what the OP asked. Posts in the thread when on to ask if it made the 300HP. My answer was no it is a short block CAPABLE of handling 300HP with the proper supporting mods and bolt ons. Yes you can buy them from JBP but they do not come with the short block.
