Finally hit the track with my sons new engine

View attachment 1715104276 we just finished dealing with a few issues in a new build we did for my sons 1970 Duster. It’s a .030 over stock crank 360 with. 600 lift roller cam and a set of open chamber 340 Edelbrock heads I had laying around that I ported and a 340 Victor intake I ported. The engine also has a set of JE flat top pistons. It’s has a 727 transmission and caltracks wilth 4.10 gears. Yesterday it ran a 6.58 and a 6.56 and today ran a 6.54. Pretty satisfied so far and I hope he can go a few rounds in tomorrow’s race
Good day, what is the duration and LSA specs on that cam?
