Any one interested in the oiling mods I did?

sending oil somewhere is one thing, how much volume blows out is what matters. the size of the passages going up to the cam bearings are not very important, what is important is what happens at the end of the passage. like your thumb on the end of a garden hose. the oil blowing out is very restricted by most cams, except at 2 and 4 with those old cams with a groove. X amount of oil is pumped into the main galley, "the fix" takes oil from the main galley and sends it to the rockers = taking some oil away from the mains. maybe the mains get the proper volume that they need.

I would think that opening up the passages in the block from the pump into the main galley would have more than adequate volume to feed the entire engine. The claimed advantage of the external line to feed the rockers is that the feed to the rockers is full time instead of the pulse oiling that the stock setup uses. Also the path the oil takes to the rockers is much more direct with less severe turns. Also if the block is tubed or the lifter bores are bushed there is much less leakage at the lifters and this volume is available to everything else that is fed from the main galley. Chrysler has been very supportive of their racers for many years and I personally do not think they would recommend oil mods that do not work. Sizilagy is an engineer at Chrysler who wrote the stroker small block book. I cannot believe that he would recommend this oiling mod if it were going to hurt the main bearing. My engine failure of 2 and 4 main proves that sending excessive volume to the rockers via the cam grooves takes the volume away from the main bearings and imho Sizilagys mod is valid for this reason.
