What oil pump/pan do I need?
I am building a 383 for my 1987 Camaro that had a 305. I am using a 1997 350 block that came out of a 1997 1500 Silverado 2wd truck.
Will the 1997 oil pan fit in the 1987 Camaro?
The catalog lists different oil pumps for a 1987 Camaro 350 and 1997 1500 Silverado 350.
SBC uses melling M55
L31 truck uses melling M155

Keep the oil pan and pump designed for the block and modify the crossmember if required to make it fit.

I found of the difference between the melling M55 and M155 pumps. The M55 has a 5/8" diameter pick-up and the M155 has a 3/4" diameter pick-up.

I pulled the L31 truck pan out and took some measurements. Before I clean it up, Does anyone know if this will fit in the 1987 Camaro for sure?

It's the 4" deep section that might cause issues. That's the area of the crossmember that might need to be modified.

I was bored so I sanded and primed the truck pan. Still needs a top coat. Hope to find out if it will fit without mods. Lol.

Good idea to check. I know the eagle crank and rods had miles of clearance in the 1997 2 bolt 1 piece block.

I assume that you don't have the 305 pan anymore. Otherwise, you would have already laid the 2 pans side-by-side to compare.

Re: What oil pump/pan do I need?
IIRC (If I Remember Correctly), I think that pan will clear the K member. However the other area to watch out for is the "notch" or tunnel for the y-pipe to pass through between the pan and K member. You don't want your oil being cooked because the oil pan is sitting on the exhaust pipe.

Re: What oil pump/pan do I need?
I'll check out the links and research.
I have 2 vague pictures of the 305 oil pan. To me it looks almost the same as the 350 vortec truck pan. But I could be way off and like you said, the notch could be not correct. The bottom sump on the truck pan does look a bit larger.

Re: What oil pump/pan do I need?
It looks like the difference between the M55 and M155 pumps is the inlet diameter. M55 = 5/8", M155 = 3/4". Guys online are saying that the change occurred around 1994-1995. I have an M55 pump in my 4 bolt main 1997 L31 383 stroker, with a Kevko 2001 stock appearing pan and their pickup tube kit for it. I got rid of all the stock truck windage tray / main cap hardware mess, then ARP studded it and had it align honed. The truck pan was in no shape to be reused anyways.
