Can anyone please tell lme what oil pan will fit a big block 68 or 69 Chevelle. The crate motors come with 6 quart pans which hit the frame crossmember. I do not wish to restrict the pan size to 4 quarts ( I know there are some tricks to run an extra quart ) I would like to run 6, 7 or 8 quarts on a new 502 and an older 454. Thanks RB

I am curious as to the concern about 4 quarts. What is the basis for this? Is there a concern about starvation during street use?
Since they originally put these on the 454, I was thinking I could go with similar for the new block. I am probably going with a new 502 in my 70SS and had planned to put in a pan they offer from chevy. I was thinking of bigger modified pan but worry about headers hitting these. I think I remember one being offered by Hamburger by Mr Gasket that was 5 quart?????
Any help from experts would also be appreciated.

Well, to be honest, I do not know as much as most of the people who post messages here, but I just kind of figured that as engines ge t bigger, so do the oil pans. I had a 6 qt pan on my LS 6 crate engine which I replaced with a 4 qt. pan, when it was seen to hit the frame crossmember, later I got a ticking sound, which does go away, and I was just never very happy with the whole situation. I figure for cooling as well as lubrication, bigger will be better...not talking huge just 6 or 7 quarts...the engine is not yet in the car, and it just feels like the right thing....others please let me have you opinions...you can never have too much information...Thanks again.....RB

Might look at it this way: Chevy sold these cars new with a 4 qt pan, providing a full warranty and knowing real well what some guy was going to do with an LS6/7 Chevelle. IMO, one of the keys to thinking about this situation is that chevy did not build/sell these engines with a high volume, high pressure oil pump. If you run one of these pumps, you would do well to consider a larger volume pan. A stock pump does not have near the problem pumping all the oil up into the valve covers/ valley area. More of the oil stays in the pan around the pickup where it's needed, not in the V/Cs where it's not. "Around the pickup" is worth remembering when you start looking at the aftermarket pans that have a widened floor. More floor area= more room for the oil to run away from the pickup.
Just a few thoughts.
