New member here, looking for advice. I have a bone stock 340 Swinger, all numbers matching, apart for a rebuild at 113,000 miles. I found 2 broken rings that can be cleaned up with a .020 overbore. I'd like to keep the compression at around 10.5-11.0 to 1. Piston recommedations? The heads are 915s just out of the shop from porting and intake matching. I also just scored a complete Crane retro roller set up with hydraulic roller lifters, custom pushrods and adjustable rockers. The cam is the 641 which is way too big for the street, but it's billet so I can have it machined down. Recommendations anyone? I was considering the beehive valve springs, too. My goal is to appear stock for minor car shows and friends, but have enough to scoot when I need to. Any advice would be appreciated.
