408 Build and Swap
Most of you on here wont care but for those who do here is my new motor. We should be installing tonight or tomorrow.
We ran into quit a few problems out of our hands. First I had two rod bearings scratched in shipping, one retainer clip broken, missing bolts, wrong head bolts, and few other things but luckily everything has worked out to my advantage.
Here are some pics of the motor build.
Specs

All ARP connecting bolts/Crank Bolt/Head Bolts
Eagle 4 inch stroker forged crank
Eagle H Beam forged rods
Diamond Forged 4.030 pistons 2cc reliefs
Diamond 1.5mm/1.5mm/3mm rings gapped for Nitrous
6.0L stage 2 ported heads
Patriot Dual Spring Valve Springs
Custom Grind Comp Cam 246/250 .631/.631 lift
Double Roller Timing assembly
Ported LS6 pump
Clevite Performance Bearings

Little of everything but mostly Drag and street racing. Hopefully for some money to offset the cost of this thing lol.
Im running Nitrous along with this motor. NX 200 wet shot so the motor will put down close to 700 whp. I just hope my subframe stays intact.
Dont worry Ill have plenty of videos to show. We are loading the car up here in a min to take over to the shop and swap it in.
