High compression with low duration cam?
If I were to use a really mild cam say 210 degrees for my F23, would there be any problems if I had say 11.5:1 compression? Could there be too much cylinder pressure? I'm currently re-thinking my daily driver and wanting a low duration cam. I'm well aware top end will suffer, but that's not my concern. There aren't many high comression low duration builds so I had to ask.

hmmmmmmmmmm, well 11.5:1 isnt all THAT high. so im thinking it wont be a big problem. i wouldnt go back to a stock cam, id go somewhere in between what you have and stock.

11.5 is actually not that big of a jump in compression. You can even use a stock cam with that. However it wont give as good gains as a little bigger with more duration cam. Cylinder pressures wont be an issue.

11.5 is perfect for a mild cam, even a little big bigger of a cam is fine just make sure you have the fuel and timing to back it up with tuning because thats were ull see the gain. As far as the 11.5c, I ran a 12.5 poorman type r as a daily and got 28 to 30mpg lol. You should have no worry about that. If anything throw a h22 head on that block that's were you'll see the most gain instead of doing head work to that single cam head.
