He Gang...good afternoon. I started pulling apart a perfectly good running 350 yesterday to try some experiments . I dismantled and washed all parts and today started buttoning up the saw. This is the first time I've sanded the cylinder adapter flat using a technique I saw on Youtube ( Thank you Mattyo!) I just took a small plate of 1/4 inch steel and a sheet of 320 sandpaper and sanded the flats until smooth.....I was amazed at how out of flat they were. I used Yamabond 4 to seal the bottom, and got a .300 squish with the gasket delete and popup piston for a 353. I used the stock cylinder as it was in great shape...I really hate taking out a good piston...I hope to find a use for it down the road! This was my first time doing a squish test, and I hope I got it right. I ordered some stainless intake clamps for a 372 that just came in a few days ago. I'm really all thumbs when installing the 346 metal clamps that lock in with a snap, and the 372 clamp is a nicely made screw clamp that looks a lot easier to install. I just took a pair of side cutters to modify the intake manifold and hope that this setup will seal OK. I hope to have it assembled tomorrow and take it for a test run. I have to believe that going from a dished piston to a popup and then a gasket delete should make a difference in power....will be fun to see how much!
