mostly street driven. 7000 max. picked everything up as a package and the whole rotating assembly is already balanced. i would have chosen different rods as well but it was too good of a deal to pass up.

thanks for all of the input so far guys. i think i'll leave that part stock from your input so far. any other oiling mods? i've ported the 90 degree adapter, more like smoothed it out, massaged the inlet to the block there too, and massaged the port on the main cap. the rockers are the ductile iron ones for w-2 heads.

Are you still up in the great white north...
I have the ream and stuff IF you wanted to go
that way that I can send you if you pay the
shipping... either way still do the main holes
with the 9/32 drill but.. thats about all you
need to do

Also... which W-2 heads do you have.. there are
a few versions.. the race ones have a milled flat
rocker stand that needs stands.. I have a couple
sets of the econo versions... long and a short
valve version that dont need the stands.. the long
valves are on my 416 right now in my street rod

I would never tube a block again. I don't know what kind of machinery you have available there but doing that by hand is a PITA. Worse yet is peening that tube never seems to work out well, the lifters do not move freely and with a flat tappet cam that is essential. If you really want to block the oil then bushing the lifter bores is the way to go.

Now having said that, it's a waste of money for what you have and are doing. I would block the oil to the drivers side galley though with a set screw.

Your best money would be spent on the oil pan and pickup. A 5/8 suction tube feeding the pump will do more than any other mods. You can also have the cam journals grooved to supply full time oil to the rockers.

I have a write up over on forabodiesonly.com in the small block engine section with some photos. I haven't been there in years but the thread is still a sticky.

You just peen the tube over and hit it with a paper roll. Takes 5 minutes. It's easier to do by hand if you drill it first then ream to size.

Like I said, it's easy enough to do by hand.
And getting the inlet as big as you can in important. 1 inch isn't too big.

Plenty of things you CAN do. Every little bit helps. Bush the lifter bores. Block the left galley (yes, even with the lifters bushed). Plumb oil to the main galley into both ends. Take the head oiling away from the cam bearings. Restrict oil to the cam bearings and the heads. Hand fit the pump to the main cap. Enlarge pickup to reduce restriction. Relieve/enlarge all oil passages.

The object of the exercise is to get maximum constant oil onto the crank and rods and minimize the amount of oil being sprayed around doing little or nothing. Most of this only requires time, some hardware and information.

wow! thanks for all the input. a lot of good ideas.
