Hi there; I'm starting to do the ground work to build a stroker motor for a '70 Fastback. I plan on using a forged crank, with H-beam rods, Aluminum heads, w/ 60-64cc chambers, and 12-14 cc dished pistons. It's been many years since Ive been current with todays technologies. So here it goes....... What are the pros & cons of Stainless Steel Vs. T-7 Aluminum, Roller Rockers? Also, Which type of piston is better, Forged or Hyper? This motor will be primarily used on the Street, and Highway., So longevity, and reliability is most desired! Your input will be greatly appreciated!
