A few questions here for the experienced: I've been going back and forth about putting in a new cam. If I do, would I need to put in new lifters and remeasure for new pushrods? I already have nice 1.5 roller rockers from Crane. I know I would have to take off my oil pan and timing chain cover again but that's not a big deal, it's just time! The engine ran great when I removed it from the car so I'm hesitant to mess with a good thing. Thoughts?[/QUOTE]
It does my heart good to see you building a sbc. Keep up the good work!
If it's a flat tappet cam best to change lifters with. A roller cam you can just swap bumpsticks (though I'd make sure I had no doubt about the lifters). Either way it's best to check your contact on the rocker to stem. A little thing we used to do was trim the corners of the timing chain cover where the ends of the rubber oil pan seal sets. Just radius enough so you can pull the timing cover with the oil pan still on.
