I get distracted with other things.
Even though I changed the weight of oil and the pressure came up, I ordered a high volume pump from Summit. I was told that it would be coming from Ohio. A week or so went by and I got busy with other things. I called to see where the pump was and they said something went wrong with the order.
I figured I'd get back to this once I got a few other projects wrapped up. I've rebuilt the front suspension in a 72 Duster, done some things around the house and shop and worked on the 2007 truck....
One of the reasons that I posted in this thread last night was because I am thinking about this project again.
When I had the engine out, I had considered the option of installing a roller camshaft. I had a solid flat tappet cam and matching lifters in the shed, a set that I had ran before when I had the 727. I pulled it because it was a bit too racy for my combination.
I was then (and still am) nervous about the reliability of a flat tappet setup. Having a known good cam in place was the one advantage that swayed me. The high initial cost of converting to a roller also swayed me. I knew this Lunati was wilder than what I wanted but it was a safe choice. Most of the guys that I know have been okay with their flat tappet setups but it still digs at me.
This week a buddy brought over a 1990 360 that he didn't want or need. It is a factory roller cam version before they went to the "Magnum" 5.9 design. It got me thinking more about the swap to a roller cam in the 440-495.
One thing I'm going back and forth with is the lifters....solid or hydraulic?
One of the things that make a hydraulic tempting is that with no valve lash, it would run much quieter.
Yeah, I know....these are hot rods and they make noise. I don't mind most of it, in fact I love exhaust rumble and a bit of cam lope. It is the clickity-clack of valve lash that sometimes annoys me. I've heard that even the hydraulic roller setups have clatter. If that is due to the lifters, wouldn't a solid roller also have clatter but be simpler and cheaper?
