• Finally !

    From Snag@21:1/5 to All on Fri Mar 25 22:46:14 2022
    Let's build a motor ! I finally got all my parts back from the
    machine shop today , tomorrow I start to assemble my 305 . Actually it's
    a 315 now , since it's bored .060" over , but the main thing is it's
    finally home and ready for assembly . I've spent the last couple of days port-matching my heads with the new Edelbrock Performer intake manifold
    and machining the tool to re-bush the loose primary throttle shaft of my Quadrajet - and installing bushings I machined in my shop . It's LOT
    tighter now ! Tomorrow I think will be crankshaft install day . I plan
    to plastigage every single bearing on the crank . I'm not taking any
    chance I can avoid on this build , I'm not going to get a chance to do
    it over .
    The particulars are :
    305 bored .060 over and flat top pistons instead of .080 dished for
    estimated c/r of 9.5:1 . These are the 601 HP heads , stock on the "H"
    motor .
    Elgin e-922-p cam , intake .444/288° ex .466/298° , lobe separation 112°
    and 214°/224° duration at .050" .
    Edelbrock Performer intake manifold w/stock Quad (full rebuild) (there's
    a 750 Holley waiting in the wings) and small/long tube headers .

    Backed up by a 700R4 with a shift kit , to a 3.42:1 rear axle .
    This is all in my '86 GMC 1500 LWB truck " Rojo Grande" .
    I'm so excited I could just shit !
