We are pulling the AEBS 4.23L Longblock from our shop car to replace it with another 4.2L but with higher compression for our race car. This motor is in excellent condition. There is absolutely nothing wrong with the motor, we just need higher compression. Includes 1/2" Head Stud Upgrade. I will sell the motor either as a longblock including Ferrea valvetrain heads with stock cams (would recommend upgrading the cams), custom head gaskets, or the shortblock alone. Price for the longblock is $9,995 and just the shortblock is $7,995.

We dynoed 780rwhp at 23psi with zero issues. I will also be selling the custom GT42 single turbo kit off of our shop car and zero mile ATS Triple Clutch as well. PM if interested.

Specs are:

4.23L Displacement
Pauter Rods
8.5:1 Custom Pistons
ARP 1/2" Head Stud Upgrade
