building a mild Daily driver 318

Try telling that to my 360. It goes 7200 for 11 years and at up to 11.2 Scr on nothing but 87E10.
My KB107s are .005 up out of the hole, and although the current gaskets are .039s, It has run with the .029s as well.It has never run less than 32* power-timing, and is happy at up to 36*. I have run 3 different cams in it with the same results; no detonation.

In any case my comparo had nothing to do with horsepower whatsoever.

I assume you have a high dollar, aluminum head, large cam 360 to be able to run on 87 octane fuel with those pistons. I doubt it is helpful to suggest this build, without careful choices, to make it streetable. Certainly not what I'd ever build and not a mild daily driver. You can build a "mild daily driver 318" a lot easier and a whole lot cheaper. Horsepower numbers are from NHRA factored numbers to give approximate gains for known combinations. Steetable and factory High Performance, so relatively mild. Finally, if you put your heads, cam, and valvetrain on a similar prepped 318 it would pull past your 7200, which is what I was saying.
