I recently began testing on my little 360 street engine and thought I would share a couple things.
The basic rundown for initial testing is;
Stock low mileage77 bottom end, small valve j heads with decent valve job,8.75 to 1 ( for now).
I started testing with an M1 dual plane, MP 450/455 hydraulic cam, 670 Street Avenger,1 5/8" generic headers.
This engine is not very exciting,but is a basis for future improvements.
After dialing in timing and jetting,it makes 360 lbs-ft torque and 310 horsepower.
I am running a stock truck style oil pan,standard oil pump, and started doing some oil testing.
The engine pulled well up to 5500 with the pan filled to one pint below the add mark . I added one pint to bring it up to the add mark,no change. One more pint to bring it above that mark,and the engine starts to lose poor hard above 5000.
It also starts losing a little pressure when coming off the high rpm,then settles back down,must be foaming the oil.
No windage tray,15/40 Rotella
More to come as time allows.

Interesting stuff. Can't wait for the next "installment".

This will be fun. Thankyou for taking the time to do this. I loved that cam back in the day. What RPM are you starting the pulls at? J.Rob

I am pulling it down to 2000 and the torque is good right out of the gate. I need to adjust the capacity valve and start a little lower.
I would like to at least start low enough to see where the torque starts to climb. Basically 350 lbs-ft from 2-4000 rpm with little variance.

What changes do you have in mind? I would be curious how a real manifold like a RPM would do on that combo

Intakes,cams,headers carburetors,and whatever else I come up with. Doing some oil viscosity testing first.

i would love to see what happens with the pint over but with a windage tray added.

Most likely will run a tray,and possibly some other oil system mods. Will be interesting to see if it does much with a relatively low rpm engine.

Did a little oil testing today, I started out with Rotella conventional15/40. Consistently made 360 lbs-ft and 305 hp.
I then switched to Rotella synthetic 5/40 oil and ran it at the same oil and coolant temps. Consistently made 366 lbs-ft and 309 hp.
I also adjusted the dyno water brake to allow me to pull the engine down to a lower rpm.
At 1500 rpm,it makes 305 tq and dips to 290 at 1800, then rises quickly to hit 355 by 2200 rpm.
I plan on doing more oil testing at a later date but need to work on some testing for an article so it may be a couple weeks.

The smallblock REALLY needs a crank scraper by it`s design and crank location in the block.

Glad to share,hopefully some things I share will help somebody.

As far as trays are concerned,I have a couple designs and ideas to try eventually.

I`ve read anywhere from 10-30+ hp w/a tray and good pan. Cool thing is you get to play with this stuff and see what your results are..............have fun.

Effects of pans, scrapers and trays will be different on dyno than on the track.

Maybe so but you can`t tell me the small block won`t pick up at the track w/good oil and windage controll...........that`s what the tray was designed for....Racing not dynoing..........

My point: measuring the effects of some oil control mods may be hard to see on the dyno but very effective under the dynamics of 1/4 mile racing.

Since I have already seen windage problems on this engine,I have no doubts we can see results on the dyno. The problem will only be worse at the track.
Most testing that ever shows improvement on the dyno ends up tested at the track later. But who is going to pull their pan and swap trays for back to back track testing on the same day?

Maybe but didn`t you read his results of TOO much oil?

I have seen airation problems in very mild small block combos.
