Has anyone had this trouble. My 302 runs great, but I've got a mechanical oil guage that when breaking hard or turning sharp and sometimes under acceleration, the guage inicates a drop in pressure momentarily until I level out. I added an extra quart (6 total) and it helped but it still does it, and I can't have fun when I'm worryin' about oil pressure. Any input?
what type of oil pump ???you may need to go after market deep sump pan if you have a high vol oil pump .....if its the factory engine wth high miles the drain returns in the heads may be pluged
Ther are no baffles in a stock pan at all. YOu can add your own pretty easy. You weld it in using some sheet metal. Helps keep the oil in the sump area instead of the rear part of the oil pan as you accelerate. This is good for daily drivers and drag racing. If you are doing road racing you will need a pan with baffles on the side as well. Edit......I would only recommend a half quart over fill. Past that your crankcase pressure raises too high and your PCV system will not be able to handle it. Resulting in blown seals/gaskets causing external oil leaks. Lance
Yea, I have a Melling pump, nothin fancy, but it still doesn't make much sense even if the pump was bad. None of the stock pans have baffles, but SBFs never have had a reputation for oil starvation. I may end up pulling the pan, but I'll keep looking for ideas. Anyone else?
SBFs never have had a reputation for oil starvation... Mine did when I had a Melling HV pump and a stock pan, thing would suck the pan dry at high rpm. Oil couldn't drain back fast enough. Put a stock volume pump back on, problem solved.
I run a melling in the new motor. 50# ar idle 60#+ at 3000 rpm. Never had a "slosh" or starvaton problem, standard pan.
Could have used your help a couple of threads back, Barry. I suggested the same thing and was basically told I did not know what I was talking about.
Yeah, it's one of those things that untill you see it happen for yourself it's hard to believe. A high volume pump should be in a high volume pan. For 99.9% of street driven cars a standard volume pump is more than enough, and probably for 90% of race cars, too. Blue printing even a stock pump can make a nice difference. When you think about it, the faster the engine spins, the faster the pump spins. So oil volume is going to increase with engine rpm anyway. I think too many magazines get caught up in trying to sell their advertiser's fancy products even when they're not needed. (This could open up a can of worms )
