      Ok so I got the motor out and ready to go to the machine shop 6 out of 7 pistons had broken ring thing that would have been the cause of my blow by haha

      I went with the .30 kB107 and changed the cam up my buddy had this one new in the box gave it to me for free so I’m going to use it it says heads will need work to work with the new valve springs

          You will love it. That's dam close to what mine is.
          KB 107s above deck 12 thou. Squaring the deck took way more than planned so comp ratio went from 10 to almost 11
          560 lift, 107 LSA.
          big valves
          Full internal ballance
          Tunnel ram and twin 4160, 460 cfm.
          4.88 rear and spool

          29X10.5X15 DOT drag radials

          100 percent "street" car.... runs all day on 91 pump swill. Transforms rubber into white smoke and fuel into smiles. (Unless your at the light next to me.)

              Oh, it's fun.

              I drive mine as much as I can. When I can afford new aluminum heads (cast iron now) I'll crank up the timing and realy let her eat.

              That is a similar build to what im doing. Mine is a gonna be a .30 over 360 im going with speedpro h116c. 9.2:1 compression. Ported 360 heads with stock valve size and a lunati voodoo 10300702 camshaft everything else is stock. Here is the card for that cam. Im not sure what to expect hp wise but it is a purely street car for weekend cruising so top hp isnt a major priority I want it to be reliable and dependable.

                  Lots a folks said 10.8 static compression is to much for iron heads on pump 91 but I can tell you it's not.
                  When I go aluminum heads I'm gonna push pump gas even more. In fact I wanna push it right to the edge and maybe just a little bit past..

                      I ran my 10.6:1 5.9 magnum on 91 pump gas. Never had an issue and it ran GREAT. Had several people tell me it wouldn't work, but I did it anyways since those were the parts I had. I pulled it apart and didn't see any signs of detonation so it went back together with aluminum heads.

                            A lot also depends on the cam and timing as well as the quality of fuel. When asked about compression and fuel, I’d rather error on the side of caution for the reader for no problems in his build than grab a few tiny hp he will never notice. Proceed at your own risk.
                            I thought the 4 cyl. were score dinner?!?!
                            Sorry about that.. blech!!!
