How much space should I look for when checking my pan to oil pump pickup?
I am doing this with clay, and want to make sure to get it right.

 

I just put it up a lil higher than it looks like it should and then set the pan down on it w/o the gasket. that way when the gasket is there it will be around an 1/8". Thats how i've heard to do it and did it that way myself. but i'd also wait to see what the guru's say.

 

Anybody? I am trying to tackle this today. I have a little more than 1/4 inch right now.

 

In my LT1 setup for road racing, Wayne Calvert ( www.waynecalvertengines.com ) used the stock "biscuit", leaving the rolled bottom edge about 1/8" off the bottom ot the pan. The screen is another 1/8-1/4" above that.

He brazed the tubing together and then brazed the tube to the pump. I'm using a Canton 242T pan.

 

I am also using the canton 242T. I have a 10% overdriven melling select, with a pickup to match the canton pan. I had somebody mention that 5/8ths was a good measurement with clay, but that seems too big of a gap between pickup and pan. My only deal is I do not want to get too close to the bottom.

I guess I will go with 1/4 inch and hope that is where I need to be.

 

With my stock volume pump and canton 242t pan the closest I could get it was 1/2" off the bottom. I would have liked to shoot for ~3/8" but all i could fit was 3 washers under the bolt on the pickup.

 

I got 1/4" but using an 8 1/4" pan......the pickup/pump was made together so I used it like it was
