The most important thing to keep in mind is that if you do these mods and use a HV oil pump you absolutely, positively must use an after-market oil pan. If you don't, you'll kill your engine from oil starvation. |
Keep it very simple.
Open and blend the feed hole from the oil pump into the block. Restrict the oil to the rocker arms with a Holley jet or a piece of round stock - something in the range of .070-.090 is normally adequate. I still like to roll the corner of the main bearing feed to match the hole in the bearing - no need to remove much metal - just detail them over. IMHO - Everything else is optional or in some cases of no value at all. |
