Default RE: Looking for advise

This past winter I pulled the heads and did a valve job. I also put in a bigger cam. Removed all polution junk. New headers borla exhaust.
Here's the problem. After a little brake in time I must of gave it to much. I now have a rod knocking. The block is in the shop and I'm looking for some advise. I don't have a lot of cash left to go all out. What kind of things should I do to the block.

Fix the reason the rod is knocking.
Did the bearing spin? Or are they simply worn out from age and miles?
Is it a bad oil pump?
If the bearings were worn, remachine the crank and rods as needed and put it back together. Don't panic yet. It may not be very bad.

same as above. Though If you caught it soon enough (and your engine guy won't try to up sale you), you'll have minimal cost to get it going

1) The best bang for the buck is a good machining for the block and properly setting it up. $1500...but you are already 1/2 there.
2) Piston by far will give a little more strength and factor of safety $670
3) I have always gone for the coated bearings, but it is more about proper setup/clearances than anything
4) Stroker won't give you any more power, so keep this of the list

Hey how are U tuning it anyway?

Sorry about the late reply. I don't know what you mean on how are you going to tune it.
