K1500 Oil Filter clearance.
I did not want to reinstall the 90 degree oil filter adapter, so I needed to find a shorter oil filter. However, I needed to account for the lower capacity smaller filter which would in turn require less oil in the pan to prevent overfilling and frothing.

I was able to use the 51069. Hope this helps someone else. See photos. Basically I need 4 less ounces per 5 quart oil change.

Awesome job volfan72! Really clean install and the truck looks great. I’m finishing up my 94 Sierra RCLB Smeding 383 install with Sniper. I had a 350 that I built in it run with the Sniper previously but cracked the starter mounting ear off of the block and decided to go 383 and a performabuilt 4L60E. This has been a little over a year in the making now but I’m also dealing with a 275K mile Michigan truck so I’m having to do some rehab along the way. I’m the original owner so I guess I’m just a little attached to it otherwise a southern truck would have saved me some grief along the way.

my engine dynoed at 426 hp / 475 lb-ft and I’m anxious to get it running. I’m running long tubes with 2-1/2” collectors. Previous 350 ran short tubes.

If the 90 degree adapter takes the large diameter filter how much do you want for it? Even if it doesn't take the big filter I'm interested!

I like where you put the coil, I'll move mine there. I have mine over where the cruise control module was.

I have an adapter and bolts on eBay for $29 + shipping. There are several of them listed by various sellers but I think I have mine listed at the lowest price. It was on my old donor engine. Forgot I still had it and just saw it in a box of parts so I figured I’d list it.

Best of luck. Hope it goes well. I completely understand the emotional attachment to things.
