    connecting rods without oil skeeters

    I was assembling my 318 shortblock yeaterday, and I noticed that half of the rod caps didn't have the oil skeeter holes for the opposite piston in them. I've never encountered this before, and find it strange. The rods have not been resized as far as I can tell, and the engine was running before...

    302 heads on a 360 magnum block

    Hey guys, i gots another question for the experts. In adding up the numbers on building another 318 shortblock to replace the one that i blew, i just cant keep myself from going back to this idea: What IF i picked up a 5.9 magnum engine from the auto salvage, with say maybe a 100k miles or so...

    I think i broke it!

    So a little backround first: Got a 65 Valiant that ive been working on for approximatley 8 yrs or so. I transplanted the original, great running, never been rebuilt, 90k original mile 318 from my 73 challenger into the car. It would have remained just that way but my buddy broke 2 bolts off in...
