Reply to "New Engine/Low HP"

panteradougMember

I think that you are seriously undercammed here.
You should be looking at somewhere around a 250 degree duration @ .050. The lift is less important . .578 lift should be fine. With 377 cubes you could easaly go to 256-260.
Overlap probably should be kept to around 72 degrees.
You are opening the door wide enough but you aren't leaving it open long enough.
It's good for 6000rpm on a 351, less on a 377. 5650 is about right.
300 hp is all that profile is going to give you.
Also that's a 300hp intake manifold as well.
There isn't anything wrong with the engine other then that.
