Here is gotapex's quote from the last thread on this subject:
We use a custom forged aluminum piston from Wiseco which results in a compression ratio of about 8.5:1
The rods are Scat's 4340 forged H-beam with ARP 2000 bolts. (These are not the Q-Lite version)
Standard green top, 42 lb Ford Lightning injectors.
In terms of balancing and blueprinting:
Each crank is rebalanced to match the weight of the new forged rods and pistons. Each block is checked for deck height, main bore size, etc. Heads and cranks and inspected as well. Due to small variations in piston size, we measure each and every one in our climate controlled quality dept and then make very closely matched sets of six. After this, each block is honed to match the set of six pistons. We do this in order to maintain very tight control over the piston-to-bore clearance to reduce the possiblilty of piston slap from the increased clearance requirements of a forged piston.
Other items which are different:
1) The camshafts are a unique profile with increased lift and duration.
2) The block is specially machined to install piston squirters on each cylinder.
3) The accessory drive setup requires a non-stock front cover.
4) We use a special dual frequency damper for engine smoothness. This is not an underdrive or lightweight type change.
5) Lighter weight 19 lb flywheel (SVT flywheel)
