I was wondering if either of you guys run the oil line trick from the oil pressure port to the one by your oil filter? Do you have any other oil mods? I currently have the oil restrictors in place but thats it.

I always did on my clevelands. Not sure if it helped, but sure didn't hurt. Never had any bearing failures or oiling problems.I formed a 5/16 or 3/8 steel line for mine. This was before the big to do about braided steel lines, plus, I couldn't have afforded them then. Wife and 2 kids and making about 6bucks an hour in 1980. No wife now, no kids at home, but one dollar hungry rust bucket of a 64 Fairlane. She can spend money or make me spend money better than any woman ever could.

Nope, I never saw any point to it. Every motor that I have blown up due to lack of oil causing a bearing to spin, has been on the second throw. All that line does in my opinion (which might be wrong, but hey,  it's an opinion), is take oil away from the front of the motor which is the exact place that will run out of oil first. I run the restrictors, polish the lifter valley, radius thje oil return openings in the lifter valley, radius the opening for the oil filter and knock down all bumps in that passage I can reach, I have .0035 clearances on the rod bearings, they are machined in an oval shape, (they measure .0035 at the parting line, and .002 top to bottom, keeps the rod bolts from "pulling in" at high rpm and using the parting line like a scraper and wiping all the oil off the throw), liteweight synthetic oil, and the high pressure spring in a high volume pump with a deep pan.

I run it, don't have any real proof that it helps or hurts but a lot of people swear by it. The bearings in all the Clevelands I've put together have always looked good with it or without it, but I've always used the restricters and a Melling HV pump with the 100psi spring. One thing I did this time, (read it in something Dan Jones wrote)is put two cover plates on the pump, in case there is any flexing. It's probably overkill because the plates are pretty thick, but I had enough clearance so I tried it, other brand pumps may be thinner. I had a section of the paper gasket between the pump and the block blow out once, my block had the number 11 stamped on both sides of the main oil outlet. With no gasket the pump actally rocked back and forth on the high spots of the stamping, make sure you file any high spots down before mounting a pump, as extra insurance put a very thin layer of two part epoxe on both sides of the gasket. Also make sure to chamfer the oil holes in the crank, I grind a slot into the leading edge of the holes in the mains, it kind of funnels more oil through, I saw a picture of this done on Roush engines when they raced trans am.Roger
