yep, Melling is a great pump and have been for years, and so far appear American made, mine was anyway.
USMC,
sorry, I didn't answer about the Cloyes timing sets. Good quality, you shouldn't have any problems with them. Cloyes are China made now tho.
Don't get too crazy on the cams. Contact Comp, Doug Herbert or other cam manufacturers on choices and possible computer upgrades because of cam upgrades.
I mentioned Doug Herbert as a cam choice mostly because the respect I had for his father Chet, and figured the nut don't fall too far from the tree. Chet was a cam designer back in the days of my racing, 60's, 70's and he was very helpful in cutting cams for you or recommending cams. He was the first I believe to make the roller cam. He based it on the Harley's he was racing at the time, setting many salt flat records. His health deteriorated and was in a wheel chair for most of his life, but still an advocate for making engines go faster.
Actually let me upgrade a little more, I know getting kind of windy.
On the topic of camshafts. Please remember that an engine upgrade is a combination of all parts involved, they have to match for the performance desired. So its based on the intake through and to the exhaust. The modular engines actually already have a pretty good cam and heads. And that cam will flow all the air those heads can use, without boost. Upgrading cams to more lift and duration "most generally" moves the torque and power curve upward in the RPM range, which is really not want you want in a heavy town driven rig. And with todays fuel injection can mess with computer controls and mellow out that NASCAR sound we would like to think we want. My recommendation after years of building engines is leave the cams alone. You will spend thousands and in this particular engine not get much if any results.
