Hello everyone, been a follower of the HAMB for quite a while but have only just signed up. Im building a BB Olds 425 and have access to a new set of Jahns forged pistons, C-1171 H RP std, and have exhausted my searching for a catalogue which tells me the piston weights. I did read one of the Hamb posts where someone had a catalogue but at that point couldn't register in the group to find out. Gotta love bad internet. If anyone has a catalogue i could download or even a copy of the page with that piston information would be great. The pistons are still available but didn't want to miss out on the price. My email if permitted, is firstname.lastname@example.org, thank you, Marty.
