I'm using Hughes roller lifters and

Didn't notice the date in the corner of #5 is 2014 so that is probably why the link is broken.
Be careful of tight clearances on old mopar blocks, I have seen spun main bearings from tight clearances and that is a block killer. When making a lot of torque and power the block will get some twist and the mains will get out of line. If you have a tight clearance the crank will rub the bearing pushing the oil out and will get hot and grab the bearing and it's all over. I would rather run the mains and rods a little loose and run a heavier oil and good pressure 60 psi at 6000 rpm. I have never lost a bearing in any small block even at 7500 rpm.
TANKS I'LL HAVE TO CHECK THE CLEARANCES using alu molnar rods and forged crank
link number 8 gives lots to think about
