Chime in with suggested cam spec's 408 build
bullet also does make a great cam using ultra dyne lobes ....talk with tim at bullet who worked for harold berkshire who owned ultra dyne cams...harold was the best cam designer in the country imoa....he did r@d work for lunati and came up with the voodoo line of cams ...bullet bought the ultra dyne molds when they closed up and tim went to work for them ....i do not know if he is still there as the last custom cam i had him do was back in 2008....give then your build and the 40200731 specs and see what they say ...if you can get tim he will do you right ....very smart man
