Thanks for the response guys! Would you consider this a full race or 3/4 race cam? Sorry I'm new to engine building, especially with the flathead! Thanks-Gabe

I had that cam in my sedan. 255” motor, 4” crank with 2x2. Ran great sounded amazing but not a ton of low end. I’ll try to post a video if I can figure it out…

**edit** my apologies! I miss read your question and you were asking about the 6015 cam- my post was for the 6014 cam. There is a video below anyway!

So much depends on what your engine is. A cam will tend to be a lot tamer in a 276" engine as opposed to a 239".

Thanks for the response, that motor sounds great! I have a bone stock '37 21 stud flathead and would like to install a cam, dual carbs...basic hop up parts. I'm assuming this would be too radical of a camshaft?

Thanks Gabe

That is a lot of overlap for not much lift. I expect a cam with equal duration but a lot more lift would make more power, and idle about the same. Or you could get a cam with the same lift but less duration and get similar power but a nicer idle.
