Installing cam bearings. New front bearing has a notch perpendicular to the bearing, from one hole to the outer edge. Inward or toward cam thrust? In case anyone's interested, 74 block, original bearings, 2 thru 5 oil holes at 2 o'clock or 8 with the block upside down.

MeanGene, I might take you up on one of those carbs. It's still stuck. Pretty sure it's the plates rusted in the holes as there was evidence of mice. I'm going to try the CRC next. If that doesn't work, maybe some weak acid. Patience is wearing thin and if there's a bunch of corrosion in the bores, carb might be junk anyway.

I have this 4100 carb. This thing is complete and untouched. I want to use it on period correct 66 Fairlane GT S code. The only issue is the secondaries are stuck. Been soaking in Kroil for a week but no go. Any thoughts on this?  It's a really nice carb and I don't want to screw it up.  Thanks!

Ross, pin height and crowns are the same on all 8. It is a temp motor till we can come with something more exotic. I'll try to talk the owner into cutting the deck. Duck...Yeah,there is a slight difference in that area. 360 pistons AND rods on a 390 crank?

Thanks!!

Thanks,gentlemen! These heads came off wrecked trucks many years ago when salvage yards still had this kind of stuff and were in surprisingly good shape. The guides aren't perfect but not needing replacement. The valves are already ground and I plan on doing a slight lap on the exhaust to see how they look,retaining as much hardness as possible. The DIY thing always comes into play with me,not out of necessity but principle. Sometimes it pays off,sometimes not. Probably never use the heads anyway but it's something to do.

I have several sets of 70s truck heads in decent shape. I would like to touch up the valve seats. Been looking at Neway seat cutters. The videos look like it's a straight forward deal. I would appreciate any thoughts on this. Not trying to put any machinists out of work but local shops are backed up and would like to give this a shot. Thanks!
