Cost Effective Swap Pan.

That's how it seems to go. The Hummer H3 Alpha (5.3 powered) oil pan is the gmpp hotrod pan. It still hangs below the crossmember. Ok for stock height cars but no go for lowered stuff Imo.
 
The H3 muscle car pan isn't even worth swapping anyways. Its under .75" shorter than the pickup pans which hang down a lot. It still hangs down a lot and i'd rather not drop $200 on a pan with essentially no improvement.

Ive put 5k miles on my stock ride height 2+2 with a stock pickup pan, mostly out of happenstance since I put the $200 6.0 in it and expected to rebuild it but never did and it's sat in the car running for 3 years.

I feel like the ctsV is the best compromise between stock pans and cost and fit.

Any reports of the 302-1 holley pan fitting?

I might have to give this TSP pan a try since I want to swap pans this spring.
 
Guys, I ordered the TSP oil pan, I figured out the for less than 20 bucks you could also get it in black which fit what I am doing on this engine. I will let everyone know how it fits once installed. I am using the holley mounts and possibly their cross member depending on how it all looks when the engine is set in. This pan saves you about 145 bucks and allows you do still use the holley stuff if it in fact works
 
Bad news guys, the TSP pan does NOT fit. it is too wide in the front. Also looking back through the pictures posted earlier in this thread of the speedway pan, it looks similar to the TSP pan. So now i am off to spend almost 400 bucks on the holley pan 🙁.
 
So it could be said by conclusion that the 302-1 and speedway pan does not fit also? Thats the first I have seen that. Is it too deep in the front and hits the crossmember?

Thanks for falling on that sword.
 
I am pretty sure neither of them will. if you look at the 302-2 pan in the front, the pan stays in between the bolting flange while the TSP pan widens out to the edge of the flange everywhere that doesn't have a bolt hole. not sure if that makes sense. So as of now I would say that if you are going the holley mount way, the 302-2 pan is the only on that fits. Its a spendy pan but looking at the way the engine sits in the frame with the holley mounts, I really think the holley stuff is the best way of going as far as fit. Their whole setup is top notch if you can get past the cost of it all.

Correct, the 302-1 pan does not fit G bodies.
 
Cool, that makes sense. This tsp pan is flush to the outside of the gasket mounting surface and has scallops inward for the bolts, the holley pan has the vertical section flush to the inside of the gasket mount surface. That extra width is the issue.

So it looks like we are back to the 302-2 pan, or the CTS-v pan as the 2 options that fit.
 
So this is the part that hits the G body crossmember on the TSP pan (red square)?

I wonder how the height of the engine impacts this? I have a stock 00 truck pan in mine with home built mounts. Fits great up front just low in the back. Basically I bolted the engine to the trans, lifted the engine so it was centered and 1/2" off the inner tie rod ends at full steering lock and made some plates to fill the gap in between the stock SBC frame mounts and the LS block. If I remember right the thing that stopped me from going any lower on the front of the engine was the tie rods and that I wasn't close to the cross member but its been 3 years.

Do you think the engine raised 1/2" and not using the full holley system this pan could be made to work? Does the holley system just slam the engine much lower than other options?

Sorry for spamming this thread, just trying to find if its the holley mounts that make this pan not work or if it won't work at all.

Would you be able to measure the height of the holley mount like the picture below from the mount bolt center to the block mounting surface?

The truck pan I know works for me any many others, not sure about the holley mounts though. This TSP pan looks thinner up front so im curious as to why it hits.

This is my setup with home built mounts using a stock truck pan. I was able to drop my oil pan last winter to take the oil pump out and change the cam in the car.

I just wonder since when I had my pan off last winter for the cam change, I was able to remove the bolts and slide a 15mm gear wrench between the pan and the block to get it low enough to remove the oil pump pickup tube bolts and remove the pump. This TSP pan looks shallower in the front than the truck pan from all indications of measurements, so I'm curious. if I stuck my engine way high, which I doubt since others run the truck pan without issue and the fact that I have a M122 blower under the stock hood, or if its Holley putting the engine low, or if it's tolerances on the car itself.
