Currently building 2 B58 forged engines at once.

Thought it would be easier

Both pretty much same spec

CP coated pistons

1 using PPM rods, 1 using carrillo

Both using ACL/king bearings and ARP studs/bolts

Both with big valve Ported heads using Ferrea oversize valves and springs

Main difference is one has our ductile iron sleeves fitted which gives us a more controlled pistons-cylinder clearance
