Planning a new 383 build that is now going to be a 400

The long side of the angle will have multiple holes to raise it on the engine stand. I will post a pic later once I have it on the engine stand!
I think I am going to make the pan, add so fluid volume and also add a stiffening frame to protect the pan! The cast aluminum is delicate and could get damaged easily!
 
please post detailed clear pictures as you do the mods.
btw, I love the fact, you took the time to fabricate,
and use a custom transmission mount/fixture.

Thanks Grumpy! There is more to come! I liked Rick's idea, I wanted a more solid mounting with bolted fastening.

I drew out a template for the tranny pan and I am going to have a peer at work cut out a piece of 3/16 or 1/4 inch plate for a retainer to go around the mounting surface of the pan and then going to build a frame to strengthen the bottom portion of the tranny. That will be after I deepen the sump of the pan to hold a larger volume of fluid. The section to the right is the area I am going to deepen for more fluid. I will also put in a drain plug in a easy access location. I am going to take off the lip on the outside perimeter of the pan and the retainer will also serve as a good clamping for the gasket between the pan and the tranny case.

Also, before I go back and do the rebuild/modify of the tranny, I plan on installing the empty case in the BulletNova and get the change in tranny mount location modified so I can easily install the built tranny in the car later!
 
be aware the shallow section of the trans pan is there to clear things like ,
exhaust pipes,frames, cross members, trans mounts, etc, so look over your application,
it may or may not require that shallow area, the trans was used in several applications and cars and ,
your car/truck may not need the shallow area.
 
Clever! I like your trans mount!
Don,t forget to add a bung for a temp sending unit also on your new pan build. Keep up the great work!
 
yes thats also a good idea! as would be mounting an aux trans fluid cooler.
Remember to check clearances, youll want too,
keep a minimum of 4"-5" of ground clearance under the transmission pan,
with two guys in the car

I already have one, go back in my thread, it’s a Deraile cooler that’s going to mount in radiator core support. I don’t remember what page it’s on but it’s there.
It will have direct air flow while traveling down the road. It’s somewhere close to when I was fabricating the shroud.

I missed that one sorry... The Deraile cooler is a nice one too!
 
Have you considered adding some fins to help cooling and stiffen the pan even more?

I'm thinking I will like the price of your pan a whole better than mine !!! ;)

The pan isn’t going to be the stiffener, I am going to build a frame over the pan itself, that will stiffen the case. The frame will be built after I deepen the pan!

I will look at that Grumpy, I may wait till after I have relocated the tranny mount to revamp the pan. If I can deepen it there also I can reduce it some. I am looking to increase the amount by 1 1/2 - 2 quarts, give it more to cool a little better.

OK, I'm really intrigued by your comment. I'm wondering how you will you did this? The Turbo Buick
guy might be interested in you plan.

Are You talking to me Rick ?
Turbo Phil no longer hangs with us.
Last I knew he wanted to Turbo charge a 4.8 LS.
Phil was unbiased. Any Engine would do.
He Likes Fox Body Fords. Ultra light. Dirt cheep at least back then.

It's Bob's project.

The Grand Prix sits lower than the Corvette. Did not say the springs. All sat low.
Truck Deep Turbo 400 pan on now.
Had A Moroso Fabricated Race deep pan on. Liked it. Catch once in awhile.
When I worked in Joliet I took the Gp to work. Caught a speed bump curb one day.
Put a scratch in the pan and leaked.
Fabricated sheet metal dents.
Crazy Ed and me talking. Did all sorts of Race fab projects with him. Covered on Digital Corvette and Grumpy seen all. Some on my website.
Bought another TH400 Moroso Race aluminum Fab pan. Put away. Want to put a skid plate on it.
1/4 inch thick sheet aluminum TIG welded on. Ed has a Miller TIG Dynasty.

Brace and protect. Can't hurt anything.

The template I drew out will be the base for the frame. That’s going to be like some of the flat rails you see that bolt on top of the sheet metal to clamp a oil pan to the block. The difference is mine will have a frame made from 1 inch wide flat bar. I will draw a picture so you can visualize it! There is a small turned up lip on the pan that I plan on removing to accommodate a wider lip for the stiffener. There will be some welding that will cause warping, this is the purpose for using studs to make sure it seals up good!
 
7F8E1DB5-2D61-4028-81F9-401D2B216E07.jpeg Hey guys been gone awhile. About to start on the tranny pan and I am going build a set of custom headers also. I am not satisfied with the Midlength headers I’ve got. I am Going to buy a set of prefab weld up headers and see if I can’t do it without using a header flange just use up a strap to seal the headers to the exhaust system. With the header flanges I will probably be dragging the ground, so I plan on getting the header collectors up in the sub frame to protect him. I just recently acquired a TIG (dry rig) welder set up, all I need is a bottle of argon and weld rod to do some practicing. Then on to the tranny pan and headers.
