OIL MODS

Hi All,

I'm looking for advice to make my small block stroker last with the odd blast to 7500rpm over the 1/4 mile.

I've looked through the post from Guitar Jones. Is there anymore to be added?

Did 3 runs last year and ended up doing in number 8 bearing crossing the line just over 7000rpm

I had a precision high flow blue printed pump and full groove mains.
All drain backs were enlarged

Most of that stuff is BS. You need to spend all you time and effort on the inlet side of the pump. You can't make the inlet too big.

You need to at least tube the passenger gallery and block off the drivers side feed. Enlarge the feed to the mains to 9/32 maybe 5/16. I wouldn't use less than 85 pounds of pressure at max RPM and 100 wouldn't bother me.

You will get to a point where you need to correct the oil timing. I've never been able to decide when that happens. I know at 7500 you better have your **** wired tight. At 8000 you need to be all over it and at 8500 one little mistake and it's over.

You also need a high volume pump. You can't get too much oil to the rods to quickly when the oil timing is wrong.
