I installed this cam straight up

Do you have good fresh air circulation? Big air cleaner, nothing blocking cool air flow?

Ya, I have a real nice big K&N

You don't know how much I appreciate your thoughts. My car is getting some floor work done on it right now. As soon as I get it back I'm going to run a compression test. All spark plugs removed and throttle wide open. That should tell me where I'm at as far as static compression. This distrbutor I have is going back on the machine and get the curve re-set.

"High volume pumps are for increased demands on the oil system such as higher RPM usage, racing, remote filters and or coolers, etc." where extra oil is needed.

this is what i believe would be the only reason you would need a hv pump. if it moves the oil so fast at 50 mph@50 lbs. of pressure that it cant cool the oil i don't know. it is JMO that if you have a tight motor with the proper clearances then a hv pump wont make no dif.

this is a statement i made on this thread last week and I got calls from 1/2 way around the world telling me how crazy i was so I decided to ask somebody that should know so I e-mail MELLING OIL PUMP CO. and ask them if you had a properly clearanced motor going down the rd. at 50 mph@2500 rpms and had 50 lbs of oil pressure, i told him I said it wouldn't make no dif. if you had a reg. oil pump or a hv pump, the oil pressure would stay about the same and this was his answer.

You are correct, use the standard pump.
The HV pump will have only a minor increase in pressure.

minor to me means not enough to make a dif.

I think most of the time (myself included) we just think we need a HV pump. I wonder if your running down the road at....say 2200rpm and your oil pressure is 50 lbs w/ HV pump and you have a stock oil pan. I wonder how close you are to running the sump dry?

with the same pressure no dif. ive just been in formed a hv pump carry a higher pressure spring than a stock pump if thats true then were not talking about the same thing. im talking about a reg. pump and a hv pump with the same pressure spring in them. if its got more pressure its gonna move more oil, but the size of the pump dont make no dif. at 2200 rpm.
