On a 500 Cad I narrow the rods so that there is .035 clearance for each pair of rods.

Make sure you have plenty of rod clearance and it should take care of your barren problem. I use to run a Pontiac motor and I was told it would seize up if I didn't. I run about .0020 rod clearance.

Oh yeah dont forget to use good rod bolts.

In the early or mid 70's buick changed to bigger oil galleries in the block. this helps a bunch. the front cover is different also.it has bigger holes in it. and get ahold of TA performance they specialise in buicks and sell the high volume pumps.

My dad found a 5/8 inch drill bit that we are using to drill out the oil passage in the block. The stock passage was a little under 1/2 inch, so this will improve flow considerably. I think this will be enough oil since I dont plan on spinning this motor over 5,000 rpm ever. I am also going to build a larger oil pickup tube. If I ***** this up (like break the bit in the block or punch through the casting) then I will go external with the line. Ill give you guys an update on how it all went when I am finished. Thanks for all your help!! I really appreciate it!!

I sucessfully drilled out my oil pickup line. My question is what I should make my oil pickup tube out of. I would like to use soft copper like you use for plumbing in your house because it is easy to work with and can be brazed easily. Will soft copper work as an oil pickup tube? Thanks in advance..
