Which oil pan on a pontiac in a boat?
Looking for some knowledge/advise on what oil pan to run in my boat. 455+.040, TRW's, ported 670's, Nunzi hyd cam.
I currently have a stock baffled pan and wish to increase the capacity and/or install an oil cooler. Rear sump, as the engine faces forward just like a car. I have ~2" of clearance below the stock pan now. What have you run in a boat in the past? now? What are the best options? Currently i am seeing 6000rpm=70mph but hoping to bring that down since i still run stock rods. The rods will be replaced this winter. I have entertained the thought of adding a sump to the stock pan myself but i am not sure how easy/beneficially that will be. I will replace the melling 60psi pump with an LPI pump/pickup when i have the motor apart next opportunity.

Nice Boat! Talk to our "Down Under" Boat Racer or to Steve Barchek (who also has a Pontiac Boat).

Which oil pan on a pontiac in a boat?
Thanks Tom.
It was actually Steve that provided me with the contact info to purchase this boat a few years back (an acquaintance of his owned it). It never really occurred to me to ask him which pan but I will do just that. I will also contact "down under", thanks for that info. I hear so many horror stories about how hard marine applications are on the oil in these engines so I figured more/cooler oil can never hurt. Sent from my iPhone using Tapatalk

So what is the largest capacity oil pan out there for a pontiac? I see canton has a 7qt pan, i was hoping to get into the 10qt area but i assume that will have to be custom.
I think a cooler would be more beneficial anyways but not sure which ones are good etc.

If you have $$$$, Think that Moroso sells John Langer's "Bad Aze" Drag Race pan that has more capacity and works very well, I am told. (But worth calling Moroso to inquire).

A full length sump just about doubles capacity at stock depth and width... drop the depth another inch for more capacity and kick outs down each side could add up to @ 4 quarts or more. Twelve to sixteen qt system colud be possible.. Clearance and fastener access along with starter/oil filter, exhaust clearance need to be factored in. Baffling is important. I'd avoid any of the factory windage trays there are better stronger choices.

Thanks for the info Bruce. I cannot do full depth at the front as a small crossmember goes underneath the pan. I have closer to 3" of clearance between the boat and pan at the rear though and could increase the depth for about 2/3rds of the pan.
T money-I found them online but noticed no pontiac stuff, I will call them on monday. 69goat1- it's a 17ft and supposedly a biesmeyer hull although everyone that looks at it says it isn't. No one can id it either, most likely a one off deal most figure. It was built for circle racing and had a ford engine in it prior to the previous owner switching it over to pontiac.

they built my circle track pan, which worked great at a very reasonable price. They do marine applications as well.

Shaker455- qjets are working great, in fact the motor runs awesome. I have a few videos but they are not very good quality etc.
I am hoping to dyno the engine this winter, guesstimate is at 550hp. My 9.5:1 car engine puts down 435 (so 500 at the motor?) to the wheels so I figure at 11.8:1 this one should be a bit more. The two motors are very similar. J.c.you- thanks for the info, I will definitely talk to them. Sent from my iPhone using Tapatalk

I have a 19' kona jet boat with a tunnel rammed 496 BBC I built that is more fun than should be allowed by law... lol mine has seating for 6 but rarely have any more than just myself or myself and 1 passenger. Most folks are scared of 90+ on water...

Nice! I have only been 70 mph on water so far, hoping a little faster this year as I am re-gearing.

Awesome, some days I wish I had more seating (mostly for the ladies lol) but I rarely have two people in my boat as it is.
One thing they all ask for, an "oh crap handle" on the dash in front of the pass seat. I might look into that this year. Sent from my iPhone using Tapatalk

An oil cooler is an absolute must. they are very easy to install,just an oil line in and out and a water line in and out. Bigger capacity just means the oil warms up more slowly.10 qt. and a cooler will be fine.
I have a 66 Hallett V-Drive flat bottom with a 425 Buick nail head.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
