Just a follow up about the weight. Out of curiosity I weight both this Scat 4.375" forged crank and also a used D4TE 390 3.78" cast crank. Scat crank was 3 lbs lighter as is. I was expecting the opposite frankly.
Scat forges 4.375" crank = 60.8 lbs (no balance metal added)
Ford 3U D4TE 3.78" crank = 63.8 lbs (10/10 and snout is down at 1.375")
