    free 5.9 Magnum with rod knock

    So a few years ago I was given a 5.9 Magnum nearly complete. It was removed from a Durango because it had a "slight" rod knock. Is there a certain rod bearing that goes bad on these or is it just as likely to be any one of them. I'd like to tear into it but would love to start with "the bad...

    What happened to Lunati's cam card info on their site?

    I was trying to find the specs of the hydraulic roller I bought a while back. Found a link I had posted. But it took me to their main page and I had to look up the cam from scratch. When I got to the page for the cam, there was no tech sheet/cam card available. Why would they do that?

    Magnum bypass hose alternatives?

    So, this is about the fourth time counting three water pumps, but no pump this time. Not terrible for 165K miles but this time the nipple in the intake is fairly well corroded and not sealing well. This is probably going to involve pulling the intake. Is there any alternative? I'm thinking...

    Gasket kits sp Felpro differnces?

    I'm seeing several different part numbers for FelPro gasket sets. I'm going to be putting my '73 318 back in soon (hopefully), and I know I need to replace the pan gasket. Eventually I'll need the intake gaskets and the timing cover gaskets. Never hurts to have extra valve cover and...

    Lets talk about "freeze" plugs...

    ...or core plugs or expansion plugs or whatever... Since I've had the pleasure of having so darned many of them fail recently, my analytical mind has been set in motion. Here are my observations, thoughts and questions, in no particular order. Is cost the only reason the factory used...

    LA roller vs Magnum valvetrain...

    I opened a 5.2 Magnum and compared the lifter gallery to my roller 318. The lifters look the same and the retention spider looks identical. Are the pushrods the same length? Can I just swap the Magnum lifters and pushrods into the LA and get oil-through for use with Magnum heads? Are the...

    pushrods for mag heads on LA

    I have a 1976 318. I have a set of 2000 Magnum heads (and exhausts). I have a set of AMC style lifters. What length pushrods do I need? Stock LA? Assuming stock bore, how much compression increase will the Mag heads give me? This could be a home for my 272/454 cam, and the...

    Anyone use the Summit 1789 cam?

    Posted this on B body side, but thought there might be a higher percentage of SB guys over here- About two years ago I ordered a Summit 6900 cam. Today I opened the box and they sent the wrong thing. I really wanted a slightly smaller but more modern split pattern cam, but might try this...

    Help ID 273-4 valve covers

    I picked up two sets of these over the past several years. I didn't realize they were different depending on year. Can someone help me ID which years I have? Thanks.

    302 head air passages

    I've read lots of posts about the air passages under the exhaust ports on 302 heads. Mine seem to have half-moon like dimples, but no holes. Anyone else have this? They are from an 87 5th Ave running driving car. It had an air pump and a thin metal tube running along the top of the DS manifold...
