Is a stock oil pan adequate for 550 hp goal and seeing occasional drag strip usage?
Yep. Weld a couple baffles in and go
Repro original style pan with baffle welded in.
In my opinion the OEM pan with the exhaust crossover cutout at the rear is very marginal for anything past stock, even with a baffle.
The minimum I feel should be TA replacement pan that does not have the cutout in the rear. This is important as it helps control the oil and holds more oil to start with.
Also baffles are a must..... not only a wide one at the rear, but also one in the front to help keep the pickup covered under deceleration.
I've built well over 1000 Buick oil pans and have never built one without baffles, front and rear. (except of course for the dry sump versions).
Examples of simple Buick oil pans......
Im going to order one from you for my 350 next year.
You need a mirror under your car when parked so you can admire that beautiful fab work....
The oil is the life blood of the whole motor so anything you can do to help the oil system do its intended job is worth it long term even if it does not add any overall power!
A pan with baffles and or a Crank scraper is worth atleast 5 hp above 4500 rpm .
Always remember this fact, good oil control means minimal air in the oil and oil being a liquid can not be compressed until air gets in it which can be compressed.
Once too much air gets in the oil it can not keep the highly loaded Rod bearings from riding on the Crank journals, or the Crank from riding on the main Bearings.
At that point it's burned and or spun Bearing time!
Thanks everyone. The modified pan will be the choice.
Lol I’m just wanting the steel one
Very true, what we’re doing with these 350’s and 455’s is WAAAAY beyond Buick’s original design
Steve Reynolds’s (SRE) Oil Pans and or oil pan modifications are “Second to None” in design as well as quality craftsmanship, ..... Period.
Thanks Larry..... appreciated.
Can those new TA pans be used in a 67 skylark? I know the frame and such are small on that series and I am concerned with clearance of a larger pan on this car.
Should be no problem from my experience. TA would know if they've had any fitment issues.
