Will the Diamond Stripper fit under a stock Chevelle oil pan? If not, can anyone recommend a windage tray that will fit under a stock oil pan?

TIA

Anyone know?

Rich, not that this really helps you. I just installed one on my 400 small block. It was supposed to fit according to 1 tech at Milodon. I had to get the die grinder out to make it work.
Like I said, really doesn't help you other than a word of caution on what the manufacturer says.

I haven't seen any claims by the manufacturer one way or another. I'm hoping someone has had some real world experience on the BBC version as you've had on the SBC version which can help me decide whether to go that route or not.

i guess you can say im kinda a believer in "trying" to get as much hp as possable out of my bbc's engines.....and i use the louvered windage trays in the bottom end..they run about 25 bucks from almost any given source, i also run the crank scrapper about 10 bucks...a lot of folks dont have the patients for this "trick".....and i also run a rear oil pump baffle that sit between the oil pump and main cap........ with just alittle tweaking everythng fits under the stock oil pans of my bbc's......

the rear baffles need a little triming back so the oil pan sits down in the right position, the windage tray needs alittle tweaking of the hands to fold the sides in just alittle...plus a ballpen hammer to "dimple" the oil pan for the studs, the extra stud has to be cut off..once the windage tray is in place and tightened.......i cut the extra threads off and dimple the oil pan.......the crank scrapper can take hours to fit......all of this helps with keeping oil off the crank...specially if the clearences are just boarder of the within limits of clearences.........of course the tighter the motor is down low the less effect this stuff has (that would seem logical).......

i dont have back to back track times to verify all of this work .but i will say the bbc's i have been building within maybe the last 8 years or better (since using this stuff) sure seem to rev quicker then before. i have built a few engines for friends without this stuff in there's because of there serious lack of funds and they just dont seem to rev near as fast.....after building so many engine over time you kinda know "how" they should respond........and to me i dont think its a mental thing because they are not in there.....its just seems they dont rap as fast.......
