Built my own oil pan and made it dimensionally like a 8 quart moroso.going to buy the pick up tube and screen from moroso and should work great.

Cool deal. You will get many suggestions, I run a S475 tial MVR gate, turbosmart racegate BOV , had Kevin from CSU built me a blow thru.
The turbo car will not like all that gear you have, while you are working on your oil pan, do not forget an oil return from the turbo. 10 an return is recommended with no up bends.
Keep the photos coming, good luck, it is a blast!

Do you have that much ground clearance for the pan?

Block looks good, like the piston coatings.

[v869tr6]

Looks like a lot of nice parts, cool to see another turbo Pontiac!
How much power are you planning, pictures of the car and plans for the chassis?

[Curious George]

Looking good so far. I wish I took more photos as mine was going together. Going in the Catalina?, agree on needing a gear change. You'll be closer to 6.0 soon and very driveable.

Noticed the stock dip stick tube. I'd like to see how you make that work with the splayed caps. I don't think the inner tube will fit and a stock wind age tray won't either. Looks good though, I'm doing a 433 but with a 671.
Keep the pics coming!

Got a 3.89 gear that I've run for years and still in perfect shape.may have to go to a 3.70 or 3.50.can the turbo return line run into the front cover at the fuel pump hole or should I go into the front of the pan.thinking that it should exit above the oil in the pan.I did lower this car a little by cutting a coil and a 1/4 out of the front but I think the pan will be ok.it rode nose high and I had to get it down.no dropped spindles for this car that I know of.I was a ford senior master tech at the time and aligned it myself.didn't know about the dipstick concern I'm going to have.I'll look at and see what's going on.Butler tells me 800hp with 12 to 15lbs boost.I'd be happy with that.I'll be conservative and will take some time to sneak up on that number.there's going to be a learning curve.bought this car from a old man for $800.he got it from his sister who was the original owner.it's always been in my home town.the old man painted it with a brush and house paint.it still has the house paint on it.couldn't find a gear and I put a 9in ford in it out of a 75 merc.moser axles,detroit locker and Daytona support.had a driveshaft made with thicker tube.made my own driveshaft loop.poly bushings,boxed lower control arms.I've got the instant center at about where my knees are at sitting in the car.pinion angle 2 degrees down.no cage or roll bar.interior is completely stock.made my own trans crossmember.removed front swaybar.made front suspension limiter. 400 trans was built by me with tci kit kolene steels and I think Kevlar bands,govenor is tricked out too.would love to do a 4l80e.More pics tomorrow

As long as the oil return lines are down with no up turns or curves. My turbo is mounted on the passenger side so I went to the front right of the pan.
I used a 8an line to my oil pan for a dip stick. while you are building you pan you can weld a bung in for it. My canton pan had a bung so I used it. Now my dipstick can not blow out because the an fitting holds it in.

[oethel]

This is it.I was loading it up to go to the track.my number has always been P400

[oethel]

Thanks JSPONT I'll consider all of that

[JSPONT]

No problem, I have been thru my learning curve already!!!
Here is my dipstick set up, I did make it shorter than the photo. I copied this idea from another person on another site.

[PONTIAC LARRY]

awesome sleeper I like it !

[Curious George]

I wanted to use fuel pump hole for return also, but like JSPONT my turbo is on passenger side and couldn't get it there without having part of the line level so I too went to the right front of the pan. People had me a little paranoid about the return part of the setup so I went way overkill with -16 line, but it works lol.

[Tom Vaught]

Basically you have gravity feed now back to the fuel pump, Lol!

Always keep a couple of good fuel tank vents on the car when you do that, because every
cup of fuel returned to the tank will have air trapped in the fuel.

The EFI guys say, if you push the fuel forward thru a 3/8" line, then send it back to the tank with a 3/8" fuel line because the engine will always consume some of the fuel and you basically just have a loop circuit up to the fuel pump regulator and back to the tank with the engine robbing some of the fuel during the fuel loop.

I plan to use the fuel pump hole as a vent for the bottom end on my Firebird, I drilled and tapped the other side of the front cover for a 1/2"npt and will have a -12 oil return.
With 800 HP the body will likely want to roll from all the power, I would think you would want that front bar back in and likely a rear bar too.

Thanks for this post, I forgot the inner dipstick tube on my engine, thankfully the engine is still on the engine stand and if I wreck the pan gasket taking the pan off I have another gasket set.

[oethel]

Short block about done.still working on pushrod length and i've got some idea's on the headers

[oethel]

Sorry bout the upside down pics.didn't know how to get em right side up.
