I done about 10 honda, subi, swaps all to a Aluminum Factory LS, every customer said it was the best thing they ever did, one or two was dead set on selling the car, then did the swap and still own the car for over 5 years, even did a VW to a LS,
Aluminum LS with aluminum everything is close to a Honda weight, if the motor stays stock Holley has a factory tune that works perfect,
I typically, take a factory Aluminum Gen V change the oil pan to a F body, change the Balancer to aluminum, change the oil pump and timing chain, add a set of LS3 Valve springs and seals,
Most of the time, Motor with lower miles, new, water pump billet brackets, Springs, seals, oil pump, chain, F body pan, holley, Adapter plate with Clutch for 2D, and ls3 intake
Will need headers,
$5600 ready to run,
