Started up the 318 in the son's 70 Duster tonight, and doesn't sound right.
Here are the details
1974 318 - stock bore, just honed since bore, round, and taper were within specs, crank ground and polished, .010 undersize on mains and rods, deck squared but minimal taken off, maybe .005
KB 167 pistons
eagle i beam rods
moly rings
Melling high volume oil pump
Comp XE256H cam
magnum heads from a 94 jeep 5.2
Chevy beehive springs
MP pushrods for the magnum conversion
crosswinds air gap manifold
Holley 4160 carb that probably needs rebuilt
electronic distributor and ecu
stock manifolds from a 75 Dart
So, finished buttoning up the coolant system, hooking up the guages, mechanical cheap sunpro gauges that were in the car. Started right up after fiddling with the timing then tried to set it at 10 degrees, but the timing mark isn't visible. Thought maybe I stabbed the distributor 180, pulled it and restabbed it, now the timing mark is visible but won't run and acts like it's 180. Turned the distributor 180 again and it will run, but sounds like something is knocking. Took a long piece of rod and used it as a stethoscope, couldn't hear any knock from oil pan, heads, valve covers, intake manifold, so might just be an exhaust leak I thought. When it first started up, oil pressure was about 45, noticed after it was running for 10 minutes or so while I was trying to find the knock sound, oil pressure was around 20.
So, looking for ideas on what to look at next?
Any ideas on why the timing mark is so far off that it seems to be out 180?
Any ideas on the oil pressure? What's normal for a melling high volume pump?
Pretty sure I remembered the plug behind the oil filter, but if I forgot it, I wouldn't have any pressure would I?
Been a long time since I built or dealt with a 318, from what I remember it seems like it's low on oil, but checked it and says it's full.
Sorry for the long post, wanted to try to provide all the info I could.
I can take a video and figure out how to post it tomorrow night, don't think the neighbors would appreciate me firing it up this late.
