    Ignition switch actuator busted

    I found one on ebay. Will it work on a '74 non-tilt? http://pages.ebay.com/motors/link/?nav=item.view&id=161736357037&alt=web

    rod knock when warm, good oil pressure. just replace bearings?

    By "warm" i mean after about 30 seconds of running. On an actual cold start it clatters horrendously for about a second until it gets preasure. http://youtu.be/O6hZi_zziVA

    rod knock when warm, good oil pressure. just replace bearings?

    So my newly-acquired 454 has a subdle rod knock, but it has good pressure and cold-starts quietly most of the time. I'm strongly considering pulling the earl pan, mic'ing the crank, and just changing the rod bearings according to wear with some vattozone .001 or .002 under bearings accordingly...

    my dirt cheap 454 build

    I'm basing the 10.8:1 with 33cc domes on the heads having about 119cc chambers like most machinists are reporting. I'll know for sure what pistons i need after I physically measure the chambers. If they're closer to 115cc as advertised, I'll use 25cc's and make 10.4:1.

    my dirt cheap 454 build

    Typically yea, but the 4/7 firing order swap puts the hot cylinders in front, allowing them to get coolant first, along with the .039 quench and singh grooves. It shouldn't ping in the summertime. Of it does ping, I'll just bump it down to 25cc domes. Im also putting huge E-fans on it and...

    my dirt cheap 454 build

    10.5 is not high compression. Plus, compression=efficiency anyway. I will eventually go with a roller cam when i can throw more money at it, along with EFI, lighter rods, etc

    my dirt cheap 454 build

    Heres an update on my build plans, since we can't edit posts here: - bowl work and singh grooves on the 781's (1975 castings), poly locks, 924's(probably) - 33cc domes (~10.6:1) - .039 gaskets - .02 deck shave to tighten the quench so it doesn't ping - dual plane, port matched - freshen then...

    my dirt cheap 454 build

    I know the term, "cheap," is relative, but I'm used to LSX engines..... So I got a K20 with a 454 that has a subtle rod knock. So I'm going to freshen it up and add dome pistons, a mild cam, air gap, ebay headers, rebuild the Q-jet, and do some mild work to the 781's that came on it. The plan...

    I'm the 2nd owner of a 74 K20 with a 454, my first old school project.

    My uncle bought this truck brand new. For a truck that has definitely been ridden hard and put away wet, it has minimal rust and dints. He installed the 454 in the 80's, and the 4speed/Tcase have been replaced somewhere along the way too, which are still tight, along with the front end. Ive...
