Valve train upgrades
I'm pulling my parts truck apart and the fairlain GT 390 motor is in incredibly great condition. It's still getting a total rebuild but it's looking like I'll be saving a ton of cash on the machining.
I'm not looking to make a high rpm motor. I think 4,500-5,000rpm's would be my max. I'm thinking a summit street strip cam kit. It's specked between the eddlebrok performer and rpm kits. The pushrods look perfect but I havnt measured them yet. I'll take them to work to do that. I don't have a caliper long enough at home. I'm planning for a double roller kit, high volume oiler and maybe some of the oiling mods I have read about. Oh yea. I'll do some port cleaning. Not gringing away at them. Just cleaning them and gasket match maybe.
Any suggestions??

I'd lean towards the Edelbrock RPM manifold (7105) and also upgrading to an Edelbrock aluminum water pump. The basic recipe should also include a 600-650 cfm carb, headers, and dual exhaust using 2.25 or 2.5-inch tubing.
Other tidbits to consider includes electronic ignition, a phenolic carb spacer, and.... hehehehe.... a "small" shot of NOS.
