| RE: Help with Cam Selection for 390 |

| I used flat tops with the 4 valve reliefs. I beleive the book states compression at 9.5. With these pistons you can run alot of lift. I ran a .572 lift with these pistons in another motor. I clayed it to check for clearance on the valves and it wasn't even close. Forgot to mention these were TRW forged. Just to throw another option at ya. Friend of mine used one of Lunatis Bracket Master II cams in his 390 and it sounds nice as well and runs strong also. Specs are .223 @ .050 with a 515 lift. Makes pretty good power. He ran 14.30's in a F100 pickup. Should make decent vacuum also. |
