Hello, I have a stock 1989 LA 360 roller motor. Compression is listed as 8:1, HP is 190@4000, torque is 285@1600. Cam is pn P5249663- hyd roller with 250/264 duration, .385/.401 lift, and 108 CL. Heads are stock 308s. I've read some complaints that these motors could be prone to over scavenging, resulting in cherry-red manifolds. I'm planning to run a cooler plug, would I also be safe retarding the cam a few degrees? Application is a 1973 Charger with a 727 and CR20 converter (roughly 2400-2600 stall behind a 360). Haven't settled on rear gears yet, maybe 3.55s for the 8.25 axle. This is strictly a street build.

Thanks
