Comp Cams XR280r thoughts to given combo

With the milder cam, extra cubes and higher flowing heads I would think your combo is less tire friendly than mine. LOL
I plan on having the battery in the trunk. I am doing the American auto wire kit and the whole car will be re wired anyway.
My progress is very slow as time has not been on my side lately. The Edelbrock Performer RPM is not available til like August or something and not holding my progress up.
I think I am going to order the AR engineering timing cover, ATI stock pulley balancer, timing set and lifters soon.
Been debating the Torrington bearings on the timing set or not and BAM lifters or the 829s or? I've read the 829s are happy in stock lifter bores? Some of the more expensive can be loose? Experiences and people's lifter bores seem to vary on this one.
