Having some issues with the 383. We have 383 stock heads, stock intake, Carter AVS and running a comp cam xtreme energy hydraulic roller (230-236 at 50). Running stock ignition. The motor diesels when we shut it off.
We are not sure if the dieseling is a problem based on the timing or based on the fuel. We suspect there may be a hairline crack in the base of the carter AVS. Initial timing is about 15 and total of 34.
We also noticed that when the car idles warming up on choke the RPM seems to climb steadily until we manually kick the throttle down off the fast idle cam.
