At first I thought they must have gotten a LS2 rotating assembly from AES, but I see that this build was based on a LSX block. I'm guessing based on the 9,000 rpm in the article that this engine is much larger bore & shorter stroke than the AES 390.

 

I've said all along you need less C.I. to make more HP with a 2300. The blower can only flow so much air, you need RPM to get more HP. On a 427 the 2300 can't flow the air needed for 1000hp. Both motors will make very similar torque though. The 390 will just be able to make more HP cuz it can spin more RPM before the blower is done.

 

A 5.3L might go even higher if you could get enough head on it. Maybe a l92 block and 4.8 crank...

 

If my LS3 ever shoots craps, that's the motor that is going back in. Comes out to about 339 cubic inches (5.5L). If you use the longer 4.8L con rods, you can even use an off the shelf piston.

 

did any body notice the crank pulley lol 50% overdriven ( not really but just sayin') . i would like to see what a f1 would do on that set up. good job thou guys allot of hard work went into that.

 

Wow! Congrats!!

 

10% larger than a stock crank pulley.

 

Here's a new video of joes 390/2300. It's got some more details pics of the engine and parts.

That maggie sounds like a damn jet engine.

 

Awesome! Anybody else notice the belt stretch/wobble in the 1:50s and 2:20s during the video? Also, was the low rpm surging at the start of the video the dyno operator playing with the throttle or the camshaft?
