383 oil pan/pump suggestions looking for some suggestions on a new oil pump, pan , and pickup.
My new motor is a forged LT1 383 that will have around 9:1 compression and be SC. I need the above items for it and have no idea where to start looking. the car will have around 600hp+.

My builder sourced me a kit from Moroso.
Oil pan #20185 (5.5 Qt capacity - LT1 specific pan)
"Blueprinted" HV racing pump #22111 (I've heard someone claim this is in fact a Melling M55HV built for Moroso)
Pickup #24213 (specific for both above mentioned pumps)
I'll add that this PAN went right on without any modifications - my builder liked it b/c he said it came already notched/designed to fit the LT1 F-Body. I'm running 6 liters of oil in this thing (6.3 Qts) and have got outstanding oil pressure (right from the very first crank of the new motor). I can't help think back to my old 355 setup when my oil gauge would read between 0kpa and the 1/4 mark at idle while at operating temp. Only under WOT did the gauge SLOWLY reach the 3/4 mark and then the minute I would let off the gas the pressure would just dive. FYI on my gauge the top mark or 4/4 reads 550 kpa - not sure what the US gauges read... Anyways, with my new 383 and Moroso setup my engine at idle while at operating temperature just barely dips below the 1/2 gauge mark. The instant I touch the throttle (and I don't mean WOT or even a 1/3 jab, but just touching the gas) the oil pressure sticks right at the 3/4 mark for as long as I'm giving it the least bit of throttle. And if/when I open her up it just stays at the same 3/4 mark. Only when the car has come to a full stop and engine is back to idle will that gauge slowly come down just below the 1/2 mark.

I use the same pan. pump and pick up and it all fits and works well. I was scared of Canton because some of the older ones had leaking issues. The Moroso fits very nicely and no leaks...And its already clearanced for a stroker crank.

My main engine has the moroso pan on it and my spare has a canton. I cant see any difference in performance between the two and niether one leaks a drop. The only reason I switched to the moroso was at the time the canton pans were on back order. As far as a pump I auctually use a Low Volume pump and cut the spring to get 45-50 psi at 7,000 w/ 0-20 Mobil one in it. These are drag race only engines if it were a street engine I would use a standard volume pump. Whatever you do buy a good name brand pump and if it comes with a paper in the box warning about performance use send it back and get something else. There were a bunch of pumps out there that were breaking due to a change in casting design/thickness. They still make those pumps but include a little paper in there warning not to use them in a performance application.
