New to Mopars. Recently installed a 408 crate engine in wife’s Duster. At first I thought there was an exhaust leak. But after checking all connections to include header flange to head
I believe the noise to be in the heads. I hear a ticking/clicking at 1800 Rpm that resembles an exhaust leak. I don’t believe it to be detonation .
Take the engine above or below that figure (1800RPM) and it becomes inaudible at least it seems
It’s a 4spd with 3.55 it spends a lot of time in this operating range on the mostly two lane roads in my area
Hot oil pressure is around 40-45psi at that RPm. I think the camshaft is Comp Cams Nostalgia Cam Type: Flat Tappet
