there is a custom twin turbo ecotec that is rated at like 750 hp

What's really impressive is that they're using factory block and head castings.
At that power level, the crank would be billet, and the pistons and rods are obviously aftermarket.
But using production block and head castings at that power level is astounding, for both the V6 and the 4 cyl.
Production GN blocks won't go that high.
Production Chevy blocks won't go that high.

Last I heard there was a single turbo ECOtec that was pushing 1000HP.

The final race engine was eventually debored and destroked to meet the category rules. Two big twin turbos were added along with a modified upper intake, but the competition engine still maintained its production lower intake, fuel rail and head castings. Although a small liner was pressed into the block to meet the class rules of a 3.5L engine, the block casting, cylinder head castings, and crankshaft all remained production components.

Like has been said a hundred times, no one has heard of 660 crank breaking. I think 1600+ HP proves that.

So is this officailly the fastest J body in history?

Yes but that isnt your normal 660 crank. While our GEN1.5*/2/3 engines are all Cast Cranks, This one here is Forged.

as much as i agree, yes our cranks for what we put them through are up to the task... i think we would see failure on any of these Gen powerplants at that level of severity :P
*Note- I say Gen1.5 as in its a Gen1 but the 86+ GEN1's that recieved the larger Main Journal Crankshaft, (as we all know early early gen1's all snapped the weak small diameter main journal cranks at the Mains like they were going out of style... to which they did LOL)
