The R5 program I was involved in used 3 squirters, 1 aimed at the exhaust pocket, 1 at the plug, 1 swept along the pin axis between the pin bosses as the piston moved from BDC to TDC. Squirter sizes were between .018"-.024".
I think 3 might be a tall order to fit inside the R3. I'm either shooting from the pan rail or snaking a tube along the webbing into the cylinder. I was going to aim at one side of the pin/piston bottom and angle the jet so it swept to the other side during the stroke. What is your opinion one using one and where to aim?

If you can position the squirter to sweep the pin and the exhaust pocket area, that's about the best you can do with one squirter, lot of heat in that exhaust pocket with a turbo. Make sure your piston guy puts at least a .090" or more lower radius in the valve pockets and a .500" or more radius between them. High hp/heat wedge stuff likes to crack between the valve pockets.
Thank you. I appreciate your info. Luckily I run a dished piston without reliefs. So in theory, the heat shouldn't be isolated to a particular area, but should dissipate evenly through the smooth dish?

I have a couple of R3 blocks that have the piston oiling. Just a small hole through block to an oil passage. I blocked mine off as they would not have been a good deal on a drag race motor with low tension rings. Bill
Hi Bill,
I have an R3 as well. Do you have a pic of where the holes are located?
Thanks, Craig
Craig, I'll try to take some shots over the weekend and post them. Thanks, Bill

Yes, no pockets at all is even better.

Photo attached, this is shot from the top of #7, the black dot is the plugged oiler.

Don't think I have. The block I had looks just like the above picture posted.
Career best 8.02 @ 169 at 3050# and 10" tires small block power.
