  • So I worked on the motor a bit yesterday - mostly I decided to leave the heads alone then simply blend the intake into the ports.

    the line illustrates about how much I need to take off. I have gaskets coming tomorrow (I don't need to shave the intake) then I'll blend and get to work assembling this little beastie

    • a question - how does FGZ fit into a 78 seat? it's like spandex only tighter for the larger of the species.....

          • talking a machinist yesterday (the one who shaved the heads and the intake) he suggested simply hogging out the holes
            the problem

            see the threads on the lower side? need to open up the hole so that doesn't happen
            grind grind grind

            looks like it worked

            I need to do a bit of minor port matching, but it worked (yay, saved $200 in machine work)

            • Wow. Those lined up nicely. Did you plan that?
              Of all the paths you take in life - make sure a few of them are dirt.

                          nowadays we validate spring - have to do it early so that if changes need made or a government agency is a bit slow it won't delay it.

                            • to answer the question of if these springs will work... no, 350# springs

                              modified my spring compressor to make it more useful.... and it is

                              • Good news, meh news..... good news is the springs on the iron heads are 485 lb springs


                                bad news is the locks are for 3/8 valves


                                and the aluminum valves are 11/32


                                I may come back later and do a mea culpa* when I should have swapped to brand-name 3/8 valves... but I'm not going to - I blow it up and those higher-compression pistons I was thinking I would upgrade to will become a necessity - remember, I'm at 10.5:1 compression and I want at least 12:1... that said, the hot rod swap meet happens before race season restarts so those valves could happen still.... good thing I'm using a reuseable head gasket

                                *which is me saying "convince me to simply update now"... I think it'll be fine as long as I don't use this in anger - but I think those chinese valves with 11/32 stems are almost a guaranteed boom.... though I've kept sketchier things together by just practicing a bit of restraint...
