|    Finally !    |

      From: Snag_one@msn.com               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 !       --       Snag        My rights don't end       where your fear begins .              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
