The trick is to find a matching pair at the auto parts store, either both with 5/8 tube size, or both with 3/4 tube. A high pressure pump is generally a good idea, but if your donor engine has lots of miles, sometimes the extra pressure is "too much" for an aged motor, and will cause oil leaks and excessive oil related issues, usually leading to leaving clouds of blue smoke from standing starts.

I am a big fan of high volumn pumps over high pressure pumps.But I guess that is a whole different thread. :-k

I agree whole heartedly, but sadly, most parts houses do not know the difference.

I had a few problems running high volume oil pumps with the V8 swap pan. The higher volume pumps would suck the sump dry of oil as soon as the engine rpm went over 4000 rpm. I had to install a shimmed stock pump to avoid this condition. A solution for my engine combo would be to add some more oil capacity to the sump area. One other problem is that the high volume pump positions the sump pickup lower in the pan. The pan I used was not deep enough and I had to modify the pickup tube when I used a high volume oil pump. If you are fabricating your oil pan you can make sure that it will accomodate the extra depth and volume that a high volume oil pump requires.

Yepper Stan.LOL-you take out the passenger seat(the wife might leave ya) and put the tank there.So now you have plenty of room for the tank and you made a statement who really wears the pants in the family. :-k


Oh yeah that"pants in the family"thing works until she takes ya to court and gets 1/2 of everything you own van included and takes the tank back out and puts the seat back in.Well as the world turns. :muhaha: :yawinkle: :muhaha:

Nothing is too wild when they are still just ideas...good idea on the dry sump. Lots of room under the van for a 6 quart or larger oil reservoir. I was just going to add onto the sides of the pan sump area to give it some more oil capacity.
