Typical Oiling Modifications

[79mopower]

well this is going to be my first r3 so i don't know much about it. and i am planning to run the 4.18 crank so i didn't think my rpm would be that high. plus on top of everything all the oiling mods would not be done by me, i don't have that kind of experience to run a drill through my block. is there any way to send my block to you so you could do all the necesary mods? i would pay for everything, i just want it done by someone who has experience with it. thanks

I wish I could help you out. But, I just don't have time with all the projects I have now. And, I am getting to the point in life where I can offer advice more than actually doing------In other words I am getting too old and tired.


I understand your apprehension at putting a drill bit to the block. But, all you are doing is improving what is already there. It's really not hard---just takes patience. GO FOR IT!!!!!!!!!!

well thanks anyway, i will try to show my engine builder some of these pics. So maybe he can do them while putting the shortblock together........i'm really sorry to bother you about this but what are your thoughts on the
P4876791AC race block? i don't have any 48 degree parts so i went with 59. Nobody around here is really heavy into mopars, and i am just getting into these cars. again sorry to bother i just got a lot of questions and can't find any answers.

It's not a bother at all---I'm just getting to the point where I can't get as much physical work done now as I did a few years ago! Show your engine guy the write up, if he has questions have him call me. Send me a PM, I will send my phone #.

was it common to have a main feed from the galley that necked down from 9/32 to 1/4 with the 9/32 being drilled approx. 2" from the main toward the galley? I am about to do the oiling mod's that you speak of in your post ,,after running this 360/408 combo for a year at the drag strip I pulled it down for a inspection and found some bearing's that I didn't like,mostly rod's and feel that the mod's would help this situation,, one question, what size restriction would you reccomend for the cam bearing's this motor has a solid roller and push rod oil's so I only need enough to lube the bearing and the oil passage has been plugged to the head at the head.

[sanborn]

Most passages from the mains to the right side galley is only 1/4" or 17/64". The real problem is many are not drilled completely. I would drill the total passage to 9/32".

Be sure and slot the main bearings to match the block. Your rod bearings will thank you!

If you are oiling through the push rods, you don't need a cam bearing oil hole larger than .080"---I know some that only use a 1/16" hole.
