The depth of the sump im guessing is the same as the 302-2 pan? Also do you guys ever plan on making a front or mid sump pan to reach out and help those of us swapping these into the non typical chassis/suspension setups? Mainly asking because I have a 75 Dart and currently our best options are a stock front sump gto pan(significant kmember modification required) sikky mid or front sump pan(no experience with them yet), or have a completely custom pan made for upwards of $500-600. Keep up the great work, the added turbo drains are a great touch seeing as ill be needing one for my 7875 setup.
Yes, the sump depth of the 302-3 pan is the same as the 302-2 pan. I've not heard any mention of developing a front sump pan. That would primarily be explained by the fact that we develop new pans based on the need for them in our LS swap systems that we develop.
That's awesome, I'll be strongly looking into one of these.
Toddoky, without asking you to crack out your crystal ball, do you foresee these becoming a sold-out item? In other words.. are there only 10 on the shelf initially with limited production runs for the next while, or should there be good production to keep up with the masses? My background thinking.. I'm wondering whether I *need* to blindly purchase now before I pull the motor and take measurements of my shoddily-modified current F-body pan, or if there is production quantity to allow me to safely wait further into the winter deconstruction phase when I can then take some fitment measurements.
Another question, will the Holley site be offering a 2D side view technical drawing complete with the important height/length measurements, like is available for 302-1 & 302-2 (assuming there are notable dimensional differences between 302-3 and the previous pans)?
Hello Frojoe, there are quite a few units available as of today, but I have no way of gauging what the sales volume will be out of the gate since myself and others have been talking about the pan for a bit of time now, so there may be quite a bit of pent up demand.
I'm sure the marketing guys will eventually put up the dimensions of the 302-3 on the Holley website as they did for the 302-1 and 302-2 pans. I can tell you that the sump length and depth of the 302-3 pan is the same as the 302-2, and so is the depth of the front end of the pan.
Where they differ is in the the fitment details, the 302-3 has chamfered corners on the front corners of the sump and a larger front crank throw pop-out than the 302-2 to clear stroker cranks up to 4".
The transition ramp profile from the front of the pan to the sump was also carved back on the 302-3 to clear the steering rack on the Fox Body LS swap using the stock K-member. That extra clearance will also benefit other applications that we are currently unaware of.

Great, those details help to explain quite a bit.. thanks!
You are correct. I think you meant 1/16". I wonder how thick the casting is? Maybe add some weld on the outside and do some grinding on the inside. I will have to think about this. Sounds like an easy enough modification.

1/6th isn't much different than 1/8. Yes 1/16th"
I had to clearance my 302-2 pan a very small amount with stock stroke an Scat H beam rods. I check without a gasket and clearance for that. With the gasket everything will be good to go.
I don't know if the -3 pan will be the same thickness as the -2 pan.
Thanks for the tip Toddoky, just placed my order a few minutes ago before they become backordered. I have a feeling the inventory will sell quickly once people know it's available.
Also, not sure if anyone noticed, but it is actually cheaper than the 302-2 pan by $10 bucks?
Toddoky I did a bunch of MS Paint line measuring and eyeballing, and it all looks good for fitment, but before I do order one now I have a question.. would you be able to give the locating distance of the turbo drain ports referenced from the back of the pan? Like in the below picture.
Would the size of that drain be big enough for a Borg S480 turbo
You would have to ask the supplier of your turbo what they recommend. As shipped, you can run a 1/2" x -10 adapter in the bungs. If you need something larger, you can drill and tap the bungs for 3/4" NPT threads.
