408 Long Block
 

This is the motor out of my Ultra4 car (offroad race car). I sold the car as a roller and now have the drivetrain to sell. The motor has one and a half races on it after a fresh rebuild. Last dyno numbers were 550hp/550lbft on 93 pump gas. Torque is all in at about 2800 rpm. About 11:1 compression. It gets up quick. Would be good for a truck application.

Specs:
Lunati forged 4.00" crank
Eagle forged H-beam rods 6.125"
Weisco flat top pistons -2cc
Mahle plasma moly rings
LQ9 block, bored 4.010, stock main and cam bores honed, decked to -.004
